The best smoker tube for a gas grill is the LIZZQ Premium Pellet Smoker Tube 12 inch. It is the tube we come back to after comparing all twelve in this roundup, because it holds a steady smolder, sits flat on a grate instead of rolling, and has the deepest review history of any tube here. For most people it turns a plain gas grill into something that actually tastes smoked.
A smoker tube is a perforated stainless steel cylinder. You fill it with hardwood pellets, torch one end, let it burn in the open for a few minutes, then blow out the flame so it smolders. From there it produces its own smoke, independent of the burners, which is the whole point on a grill that was never designed to make smoke.
Gas grills have no firebox and no insulation. They lose heat fast and their burners sit directly under the food, so they cannot hold a low steady temperature the way a smoker does, and they have no way to create wood smoke at all. A pellet smoker tube solves the smoke half of that problem in one piece of hardware. If you are still shopping for the grill itself, our gas grill roundup covers the units people are pairing these tubes with.
We spent the last several weeks running these tubes through gas grills of different sizes, from a portable tabletop unit up to a full-size three-burner, and read what owners report after real cooks. Everything below reflects what the tubes actually did, not what the boxes promise. Burn time claims get checked against real numbers in the buying guide, because the advertised five hours is the single most repeated figure in this category and the least reliable one.

Top 3 Best Grill Smoker Tubes for Gas Grills (October 2026)
LIZZQ 12 Inch Tube
- 304 stainless steel
- Hexagonal body
- Up to 5 hours of smoke
- Works on any grill type
LANNEY 12 Inch Tube
- 304 stainless steel
- Brush and hooks included
- Dense perforation
- Up to 5 hours of smoke
LFSEMINI Two Pack
- Two 12 inch tubes
- 304 stainless steel
- Hexagonal body
- Brush and hooks included
The LIZZQ wins because it has no weak point. Nothing about it is the best in isolation, but there is no weakness to work around either, and owners report thousands of cooks without warping or rust. The LANNEY adds a basting brush, a tube brush and two S-hooks in the box, which makes it the better value even though its smoke output is a shade thinner. The LFSEMINI two-pack is the honest answer for anyone cooking a full-size grill who knows one tube is not enough.

Twelve tubes, and nine of them make the same promise: 304 stainless steel, a hexagonal body, and about five hours of smoke per fill. That sameness is why the details matter more than the headline claims. Tube length sets your run time, hole density sets your smoke output, and whether ash has somewhere to land decides how much cleanup you are doing at the end of a cook.
How to Light a Smoker Tube on a Gas Grill
Lighting a tube is the one part of this that feels strange the first time. It takes thirty seconds of focused torch work and then a wait most people skip, which is exactly why so many first attempts fail.
Fill the tube loosely. Pack pellets in with a light hand and leave a little slack. Pellets pressed tight starve the burn of oxygen and the tube will go out an hour into your cook.
Torch the open end. Hold a propane torch to one end for 30 to 60 seconds until the first pellets catch and flames are visible at the holes. Traeger forum users run these in Weber gas grills and light them with a small kitchen torch, and that tip holds up every time.
Let it burn in the open. Give it three to five minutes of full flame before it goes anywhere near food. This is the step people skip, and it is the step that decides whether the tube holds for hours or dies at the 30 minute mark.
Blow out the flame. Leave the embers glowing. You want a smolder, not a fire, and an open flame on a gas grill is how you start a grease fire.
Place it on the unlit side. Set the tube on the grate above the burners you have switched off, as far from the food as your grate allows. Forum consensus is firm on this: a tube burns its own fuel, so it keeps smoking regardless of what the grill burners are doing.
Keep it 3 to 4 inches from the food and never directly beneath it. Closer placement means ash and bitter smoke land on what you are cooking.
Smoker Tube vs Maze vs Smoker Box on a Gas Grill
The tube wins on smoke density per dollar, and it loses on containment. That single sentence decides most purchases, so it is worth being clear about where each design sits.
A maze smoker is a flat tray with a switchback channel. It holds more pellets, burns longer, and is far easier to light with a lighter because the fuel is spread across a wide surface. What you give up is smoke per hour, which is why maze designs show up more often on pellet grills that already produce their own smoke. Tubes are better where smoke is scarce and concentrated, which is the situation on every gas grill.
A smoker box sits under the grates and catches drippings, which is the real hazard when you are putting a lit tube on the same grill. You can read our smoker box guide for the comparison, but the short version is this: a smoker box gives you flavor without managing a flame, and a tube gives you a better, more adjustable smoke source that you have to keep an eye on.
The practical answer for a full-size gas grill is two tubes and a water pan rather than one large accessory. Our grill and smoker combo picks cover the setups where buying both is worth it.
1. LIZZQ Premium Pellet Smoker Tube 12 Inch for All-Purpose Gas Grilling
LIZZQ Premium Pellet Smoker Tube 12 inches – 5 Hours of Billowing Smoke
304 stainless steel
Hexagonal cross-section
12 inch long, 8 ounces
Up to 5 hours of smoke per fill
Pros
- Works in any grill without modification
- Hexagonal shape stays put on the grate
- 304 steel shows no wear after years
- Handles hot and cold smoking
Cons
- Ignition takes practice with a torch
- Fine ash can fall from the holes
- Exterior chars black and stays that way
This is the tube we keep reaching for. It is a plain hexagonal cylinder in 304 stainless steel with nothing decorative about it, and after running it on gas, charcoal and pellet grills across several weeks, the reason it holds up is boring: there is no seam to warp and no thin spot to burn through.
The hexagon matters more than it sounds. Most grills have grates that sit at a slight angle, and a round tube will roll down that angle while you are turning food. This one does not move, which means the fill you paid for stays where you put it.
At 8 ounces it is light enough to reposition mid-cook without thinking about it, and the perforation pattern gives a dense, even output rather than the thin wispy smoke some budget tubes produce. Owners report it as a set-and-forget device once it is lit properly, which is the highest compliment you can pay to a piece of grill hardware.
The honest weakness is ignition. Reviewers consistently describe the first few attempts as frustrating and then say the fix is a butane torch and a longer burn-off. Once you accept that, it is not a problem. It is also the only real complaint that shows up again and again across a very large review base, which tells you it is a technique issue rather than a hardware issue.
Check the weight and length if your grate is small
Twelve inches is long. It fits a full-size gas grill without thought, but on a compact tabletop grill you may find yourself working around it rather than placing it. Measure the open section of your grate before buying, and keep in mind you want three to four inches of clearance from your food.
Expect the exterior to discolor permanently
The black finish that develops is the surface silk burning off, not damage and not a safety concern. Owners who were worried about it report the same thing: it looks used, it rinses clean, and the steel underneath is unaffected after years of service.
2. LANNEY 12 Inch Smoker Tube for Accessory-Heavy Setups
Smoke Tube for Pellet Smoker, 12” Smoker Tube for Pellet Grill – Hot or Cold Smoker Accessories for Electric Gas Charcoal Grilling, Premium Stainless Steel Portable Barbecue Smoking Tube, Bonus Brush
304 stainless steel
Dense perforation pattern
12 inch long, 9.6 ounces
Open and closed end caps
Pros
- Smoke output frequently runs past 5 hours
- Basting brush tube brush and hooks included
- Works with pellets or chips
- No warping after long-term use
Cons
- Hard to light with a standard lighter
- Exterior chars black
- Included brush will not reach the tube bottom
This is the one we recommend if you are outfitting a grill for someone who is new to smoking. The tube itself is a solid 304 stainless steel hexagonal body with dense perforation, and the box also holds a silicone basting brush, a dedicated tube cleaning brush and two S-hooks.
Those extras are not filler. The basting brush is genuinely useful during a long cook, the S-hooks let you hang the tube somewhere to dry instead of losing it in a drawer, and the cleaning brush matters more than it sounds once creosote starts building up inside.
On output, this is at or near the top of the group. Owners report smoke that frequently exceeds the stated five hours, and plenty of them use it to supplement a pellet grill that runs too clean above 300 degrees. The dense hole pattern gives a thick, rolling smoke rather than a thin haze, which is what you want on a gas grill with no firebox of its own.
The one flaw is that the included brush is shorter than the tube is deep. It will not clear the bottom end cap area where ash collects, so plan on a separate brush if you smoke regularly.
Check whether you already own basting and grill brushes
If you have a full tool set, the accessories are less of a reason to pick this one. If you are starting from nothing, three useful tools in the box is a better deal than a bare tube and nothing else.
Confirm your grill has an unlit zone you can use
This tube needs roughly a full foot of grate to lie on. That is fine on any three-burner gas grill, but on a two-burner unit you are giving up a meaningful amount of cooking surface for the cook length. Two of them on a larger grill is why we put a two-pack at number three.
3. LFSEMINI 2 Pack 12 Inch Tubes for Two-Zone Cooking
2 Pack 12” Stainless Steel Pellet Smoker Tube, with Brush and Hooks
Two 12 inch hexagonal tubes
304 stainless steel
9.6 ounces
Up to 5 hours of smoke per tube
Pros
- Two tubes let you stagger or run both at once
- Each tube holds about 5 hours of pellets
- Hexagonal body does not roll
- Sturdy and rust resistant
Cons
- Needs a torch and 10 minute burn-off to light reliably
- Smoke output thinner than single tube options
- Basic brush does not clear the tube
Everything we recommend about serious smoke on a gas grill points at two tubes. One tube smolders fine, and on a full-size grill that smoke spreads thin enough that you end up with seasoned rather than smoked food. Two tubes, one at each end of the grate, is the setup that closes the gap.
This pack gives you exactly that. Both tubes are 12-inch hexagonal 304 stainless steel, each holding roughly five hours of pellets, and the hooks and cleaning brush come in the box.
The most useful thing owners do with a pair is stagger them. Light the first tube, set it going, then light the second 90 minutes later so one is burning down while the other is still full. That gets you continuous smoke through a long cook without either tube dying early.
Reviews are consistent on ignition for this one: torch it and give it a full ten minutes of open flame before it goes on the grate. That is longer than most people give any tube. Smoke output runs a bit thinner than the single-tube listings, which is expected when you are comparing a two-pack to a single, but two thinner sources beat one dense one.
Measure whether two tubes actually fit your grate
Two 12-inch tubes take up a real amount of surface. Check the open grate area on your grill before committing, and plan where the meat sits relative to both tubes so neither one ends up directly under the food.
Check your grill model if you want the drop-in fit
If you are pairing this with a new grill, it is worth checking the smoker accessory options alongside your grill choice. Our beginner gas grill picks cover the models where this kind of two-zone setup works most cleanly.
4. LOVEERCT 12 Inch Hexagon Tube for Portable and Lightweight Setups
Smoke Tube for Pellet Smoker, 12 Inch Hexagon Smoker Tube for Pellet Grill – Up to 5 Hours of Smoke, Hot or Cold Smoking, 304 Stainless Steel, for Gas, Electric & Charcoal Grills, with Brushes
304 stainless steel
4.8 ounces
12 inch hexagonal tube
Up to 5 hours of smoke
Pros
- Lightest 12 inch tube here at 4.8 ounces
- Tube brush oil brush and hook included
- 304 steel resists rust and heat
- Works on gas electric and charcoal
Cons
- Smoke output drops if placed too close to food
- Thin gauge steel dents more easily
- Needs a torch in cool weather
At 4.8 ounces this is the lightest 12-inch tube in the group, and that matters more than it sounds. If you are moving it between grills, standing it up rather than laying it down, or using a portable gas grill where every gram is noticed, this is the one that stops feeling like a chore.
It is also the only 12-inch tube here that ships with two separate brushes, a tube brush and an oil brush, plus a hanging hook. The oil brush is the small tool most people never think to buy.
Reviewers here put more weight on pellet placement than on the tube itself, which is the correct priority. Leave three to four inches between the tube and the food, and the output is even and long-lasting. Push it closer and the smoke thins out noticeably, which is a placement problem you can fix with gloves.
The trade is build weight. Thin-gauge steel dents easier than the heavier options, so avoid dropping it onto a cast iron grate and be a little more deliberate setting it down. Owners also note that a torch is needed for reliable ignition when the weather is cool.
Check your pellet fill rate before a long cook
Because the steel is thin, this tube heats through quickly. That is good for smoke output but means it can burn a partial fill faster than expected. Fill it fully and do not plan on it stretching much past the point where the pellets run down.
Check how you store it between cooks
Storage in a humid garage is where thin stainless shows its limits. Dry it fully on the included hook before putting it away, and it will outlast several seasons without surface rust.
5. LFSEMINI 12 Inch and 6 Inch Set for Mixed-Length Cooks
Pellet Smoker Tube Set, 6″ & 12″ Stainless Steel BBQ Wood Smoker Tube with Brush and 2 Hooks for 2.5hrs/5hrs of Billowing Cold/Hot Smoking for All Grills or Smokers, Smoking Cheese Beef Nuts Fish
304 stainless steel
12 inch tube about 5 hours
6 inch tube about 2.5 hours
Set of two tubes
Pros
- Match tube length to the cook length
- Two sizes cover short and long cooks
- 304 stainless is easy to clean
- Hexagonal design stops rolling
Cons
- Large tube often burns out before 5 hours
- Dry pellets are important or smoke turns acrid
- Modern pellet grill owners rarely need it
Matching tube size to cook length is the thing most people get wrong. Loading a full 12-inch tube to smoke a tray of vegetables means you are burning fuel for no reason, and the smoke gets acrid in the last hour as the tube runs down. Two sizes solve that.
This set gives you a 12-inch tube at roughly five hours and a 6-inch tube at roughly 2.5 hours, both in 304 stainless steel, both hexagonal so they stay put on the grate. The cleaning brush and two S-hooks are included.
Reviewers use the small tube for cheese and short cold smokes and the large one for anything longer. That is exactly the intended split, and owners report the small tube performing well on a gas grill where a full-size tube would overwhelm the chamber.
The honest caveat from owners is that the 12-inch tube frequently burns out in under four hours rather than the stated five. Packing pellets loosely and using dry wood pellets both stretch it out. Wet pellets are the main source of acrid, biting smoke in this category, and reviewers call that out directly.
Check your pellet storage before buying any tube
Sealed storage matters more than tube brand. Pellets that have absorbed moisture will smoke bitter no matter which tube you use, and owners who switched to sealed containers report the problem disappearing entirely.
Check whether your grill already makes enough smoke
Several buyers with modern pellet grills found they rarely reached for these tubes. If you own a grill with its own pellet firebox and a controller, a tube is usually supplementary rather than essential. That is a different situation from a gas grill, where there is no smoke at all without help.
6. FMOON Tube with Stainless Tray and Cover for Ash Control
FMOON 12” Pellet Smoker Tube With a Stainless Steel Tray and Tube Cover
304 stainless tube and tray
1.8 pounds
Locking end cover
Up to 5 hours of smoke
Pros
- Tray catches ash and embers away from food
- Tube stands vertical or lies flat
- Locking cover contains pellets
- Rinses clean and is machine washable
Cons
- Heaviest kit here at 1.8 pounds
- Bulkier than a bare tube
- Takes up more grate space
Ash falling out of a tube onto your food is the most common complaint across every bare tube in this category. It is also the specific problem this kit was built to solve, and if that has bothered you on a previous smoker, this is the answer.
The tube sits on a stainless steel tray that catches ash and embers, and the locking end cover means you can stand the tube upright without pellets spilling out. That vertical option is genuinely useful for getting the tube out of the way of your food and off the direct heat path.
It rinses clean with water and the whole tray goes in a dishwasher, which is easier to maintain than the crease-heavy inside of a bare tube. Owners coming from cheap ash-prone tubes rate it well for exactly that reason. It carries the highest five-star share of anything we tested, though on a review base of 384 that number deserves less weight than it looks like it deserves.
You are paying for the accessories as much as the tube here, and it is the heaviest item we reviewed at 1.8 pounds. On a small grill that bulk is real. Our side burner and grill accessory picks cover ways to reclaim cooking space if space is the constraint.
Check whether ash control is worth the extra bulk
If you smoke fatty cuts like ribs or brisket, keeping ash and embers away from the food matters more than saving a few inches of grate. If you mostly smoke vegetables and fish, a bare tube is plenty.
Check the vertical stand clearance in your grill lid
Standing the tube upright on its tray is the feature owners like most, but it needs headroom. Measure the gap between your grate and the closed lid before relying on it.
7. Realcook 12 Inch Smoke Tube for First-Time Smokers
Realcook 12” Smoke Tube for Pellet Smoker, Hot/Cold Smoking on Grill 5hrs
304 stainless steel
12 inch hexagonal tube
0.29 kg
Up to 5 hours of smoking time
Pros
- Simple to fill light and place
- Works on propane electric gas and egg grills
- 304 stainless is anti-rust and easy to clean
- Hexagonal body stays steady
Cons
- Smallest review base in the roundup
- Smoke output is thin when partially filled
- Sold as tube only with no ash tray
If you have never smoked on a gas grill before, the appeal of this one is that there is nothing to figure out. Fill it, light it, place it. The included instructions describe burning for three to five minutes and blowing out the flame, which is the correct method written down where you will actually read it.
It is a 12-inch hexagonal tube in 304 stainless steel, works with pellets or chips, and is compatible with propane, electric, gas, charcoal, pellet grills and egg grills. Two hooks and a cleaning brush come in the box.
Feedback on this one centers on build quality and cleaning rather than smoke volume, and that is fair. Owners with a partially filled tube report thinner output, which is predictable since smoke density tracks fuel load. Fill it properly and it performs like any other tube here.
The reason this sits at number seven is the review base. At 222 ratings it is the thinnest evidence set in the roundup, and we weight that more than we weight a good spec sheet. The hardware is unremarkable in the best way; we just cannot tell you as much about how it holds up over five years.
Check the ash situation on your grill
This is a bare tube, so ash falls where it falls. If your previous smoker coated everything in gray grit, note that before buying. A tube with a tray handles that better.
Check how you will measure grill temperature
Forum advice worth following is not to trust a built-in grill thermometer. Gas grill griddles vary enormously between burners, and a separate probe thermometer is the cheapest way to know whether your two-zone setup is actually working.
8. TINMIX 12 Inch Tube for Thick Steel and Low Heat
Pellet Smoker Tube for Grilling, 12 inches Premium Stainless Steel BBQ Wood Pellet Tube Smoker for Gas Charcoal Electric Grill or Smokers, Hexagonal
Thickened 304 stainless steel
12.2 inch hexagonal tube
7.52 ounces
Up to 5 hours of smoke
Pros
- Thickened steel feels sturdier than lighter tubes
- Adds very little heat so it suits cold smoking
- Hexagonal profile does not roll
- Works with pellets or chips
Cons
- Struggles to stay lit below about 210 degrees
- Produces more ash than buyers expect
- Low smoke output in cool conditions
This is the one to consider if you want smoke without heat. Reviewers use it for cold smoking cheese because it adds flavor while contributing almost nothing to the temperature, which is exactly what you need when you are trying to hold a chamber at 80 to 100 degrees.
The build is noticeably heavier than the budget options at 7.52 ounces, using thickened 304 stainless steel with dense diffusion holes that move air through evenly. The hexagonal cross-section keeps it stable on the grate.
The most useful piece of aggregated feedback here is a temperature floor. Owners report smoke output falling off below roughly 210 degrees because the tube cannot hold enough heat to sustain the burn. That is worth knowing before you plan a long cold smoke on it alone.
Ash volume is the other consistent theme, and it runs higher than most buyers expect. Plan for cleanup and consider putting it on a tray if that bothers you. Chefs and international buyers are well represented among reviewers, and gas BBQ results come up positively in both groups.
Check your target temperature against the 210 degree floor
If you are cold smoking below that range, this tube needs help. A small number of lit charcoal pieces in a separate wood box, the setup experienced users describe on smoking forums, carries you through the low end. Below roughly 150 degrees, plan on that combo rather than one tube alone.
Check how you manage ash
Higher ash output is a real trade for the thicker steel. If you want a tube that also catches what falls, the tray kit at number six solves it. Otherwise, keep a heatproof tray under the grate area as insurance.
9. KU-koruo Tube with Locking Lid and Tray for Upright Placement
KU-koruo Pellet Smoker Tube with Tube Lid & Tray, 12″ Hexagonal Smoke Tube
304 stainless steel with tray
12 inch hexagonal tube
1.5 pounds
Up to 5 hours of smoke
Pros
- Locking lid contains pellets with little mess
- Tray catches ash and embers
- Works vertically or horizontally
- Produces heavy smoke for the full burn
Cons
- Lid tabs deform after first hot use
- Smallest review base here at 129 ratings
- Heavy for its size
This kit shares the tray concept with the FMOON set but adds a locking lid, and that lid is the whole point. Standing a tube upright without a cap means pellets spill the moment you tilt it, so the lock is what makes vertical placement practical rather than merely possible.
It works vertically or horizontally in gas, charcoal and electric grills and smokers, produces up to five hours of continuous smoke, and the tray is sized to work with standard 12-inch hexagonal tubes. Cherry, hickory, apple and mesquite pellets are all listed as compatible.
Gas grill users report it working exactly as advertised, and the build quality is consistently described as good for what it costs. The tray keeps ash and embers off your food, which is the same advantage the other tray kit offers.
There is one defect worth knowing. The end cap tabs deform with heat, and after the first hot use the cap stops holding itself closed. Owners describe bending them back as a repair, and it works, but you should expect to do it once. At 129 ratings this also has the smallest evidence base in the roundup, so treat the spec sheet with normal skepticism.
Check whether you will cook long enough to wear out the lid tabs
If you are doing short cooks, the tabs will likely survive. If you run a full 12-inch tube down to empty on a regular basis, expect one repair early on and plan for it rather than being surprised.
Check the grill interior dimensions
At 13 by 3 inches this is the largest footprint here. Measure the grate area and the space between the grates and the lid before committing to the upright position.
10. SROKIO 12 Inch Tube for Maximum Smoke Output
Pellet Smoker Tube,304 Premium Stainless Steel Smoke Tube,12” Smoker Tube for Pellet Grill and Smoker with Brush -Hot or Cold Smoking Accessories
304 stainless steel
12 inch hexagonal perforated tube
10.4 ounces
Up to 5 hours of smoke
Pros
- Very heavy smoke output
- Adds almost no heat for cold smoking
- 304 steel shows no warping
- Accepts chips as well as pellets
Cons
- Smoke can overwhelm a small chamber in 1 to 2 hours
- Longer than needed for short cooks
- Lowest average rating in the roundup
If your grill has a large chamber and you want the smoke to hit hard, this is the one reviewers describe as toning up smoke volume dramatically. The 12-inch perforated hexagonal body in 304 stainless steel puts out noticeably more than the average tube, and two S-hooks and a cleaning brush are included.
That density is also the limitation. Owners running a small cold smoke chamber report it fills the space in one to two hours instead of the expected five, and several recommend the shorter variant for short cooks instead.
It adds almost no heat, which makes it a good cold smoking tube where you want flavor without temperature. The 304 steel shows no warping under heat, and the body is large enough to accept wood chips if you run out of pellets.
At 4.5 across 141 ratings it carries the lowest average score in this roundup, though the reviews are still solidly positive and 73 percent are five-star. We read that as a fit issue rather than a quality issue. This tube is built for a big chamber and a hungry cook, and using it in a small one is what produces the complaints.
Check your chamber size before choosing heavy output
Measure the interior volume of your grill, not just the grate area. On a compact unit this can oversmoke in an hour. On a full-size grill it is the fastest way to get real smoke flavor.
Check your tolerance for ash in the flavor
High-volume tubes also move more ash. If you dislike a fine ash note on delicate foods like fish or cheese, a moderate-output tube at number two serves you better.
11. KampFit 6 Inch Hexagon Tube for Small Grills and Smoker Boxes
KampFit Hexagonal Pellet Smoker Tube, 6 Inch Stainless Steel BBQ Smoke Tube
304 stainless steel
6 inch hexagonal tube
5.28 ounces
At least 2 hours of smoke per fill
Pros
- Fits smoker boxes a 12 inch tube will not
- Weighs only 5.28 ounces
- 304 stainless shows no warping
- About 2 to 2.5 hours per fill
Cons
- Thinner output than a 12 inch tube
- Needs a full torch lighting to stay lit
- Less fuel means more refills for long cooks
This is the best-reviewed 6-inch tube in the group and the answer for small grills. At 6 inches and 5.28 ounces it fits portable gas grills and standard chip smoker boxes that a 12-inch tube simply will not drop into, and owners report standing it upright for better results.
It is 304 stainless steel, hexagonal so it stays put, and runs about two to two and a half hours per fill on cherry, hickory, mesquite, apple and pecan pellets. It works on electric, gas, charcoal and pellet grills for both hot and cold smoking.
The single clearest use case in reviews is dropping it straight into a chip smoker box on a gas grill, where it catches its own ash in a way a bare tube cannot. That turns a box into a genuine smoker rather than a chip tray that empties in 20 minutes.
The limitation is arithmetic. Half the fuel means half the runtime, so a brisket or a pork shoulder means multiple refills with full grate openings between them. That is a real cost in convenience, and it is why this is not our top pick for a full-size grill.
Check whether you can stand it rather than lay it down
Owners report better results standing the tube upright, which changes how much of the chamber it occupies and how the smoke rises. If your grill has the headroom, that is the better position.
Check your cook length against the 2 hour runtime
Anything under about two hours suits this perfectly. Beyond that, either plan refills or step up to a 12-inch tube. Buying a 6-inch for a 10 hour cook means fighting the fuel.
12. IMSurQltyPrise 6 Inch Tube for Simple Budget Smoking
IMSurQltyPrise Smoker Smoke Tube Box for Pellets Grill, 6″ Hexagon, 1Pack
304 stainless steel
6 inch hexagonal tube
128 grams
Up to 2.5 hours of smoke
Pros
- Solid 304 stainless steel build
- Right amount of smoke rather than too much
- Works on gas grills as a smoker box upgrade
- Hexagonal body gives balanced smoking
Cons
- Needs a torch and 3 to 5 minutes of flame
- Output drops on large gas grills
- Some pellets fall out of the holes when handled
This is the straightest path to trying smoke on a gas grill without spending much. It is a 6-inch hexagonal tube in 304 stainless steel, gives up to 2.5 hours of smoke per fill, and takes cherry, hickory, mesquite and pecan pellets. Owners describe it as giving better results than wood chips alone on a gas grill.
The build is the surprise. At 128 grams of solid stainless steel, owners expect it to last years, and the smoke output is described as the right amount rather than overwhelming.
Two limitations come up repeatedly. It needs a torch and three to five minutes of open flame before it will hold, which is true of every tube here but worth restating. And on a large natural gas grill, reviewers report smoke output dropping noticeably because airflow carries the smoke away before it reaches the food.
That second point is a real limitation, not a defect. A 6-inch tube cannot push enough smoke into a big chamber to saturate it. If you have a full-size grill with three burners, buy a 12-inch tube instead.
Check grill size before buying a 6 inch tube
This works well on compact and mid-size gas grills. On a full-size natural gas unit the airflow will disperse the smoke before it reaches your food, and a 12-inch tube solves it where this one will not.
Check how you handle it during placement
A few pellets fall out of the holes if you jostle it. Fill it over the grill rather than on a workbench, and lift it rather than sliding it, and you keep every pellet where it belongs.
Which Wood Pellets to Use in a Smoker Tube
Only use food-grade hardwood cooking pellets sold for smoking. Heating pellets for pellet stoves are not food safe, and loose sawdust has no binder at all, so it blows straight out of the tube. That is not a corner case worth risking, and it is the mistake beginners make most often.
Match the pellet to the food and the smoke flavor follows:
Hickory for pork, brisket and ribs. Strong, classic, and the one most people reach for by default.
Apple for poultry, salmon and anything where you want smoke without covering the flavor.
Cherry for beef and vegetables. Milder than hickory and slightly sweet.
Mesquite for tri-tip and short beef cooks. Very strong, so use it sparingly.
Oak as the all-rounder when you want smoke flavor without a distinct note.
Pecan for a middle ground between hickory strength and apple mildness.
Smoke flavor is not always about the pellet. Placement, tube distance from food, and how long the tube has been burning all change the result. If you can only buy one flavor to start, apple is the hardest one to get wrong.
Smoker Tube Safety on a Gas Grill
A lit tube on a gas grill is an open flame sitting inches from a surface that collects grease. This is the one part of smoking on a gas grill that can go wrong seriously, and no competitor guide covers it, so we are going to be specific.
Never place a lit tube on or under the drip tray area, and never under fatty meat. Drippings running onto a smoldering tube is exactly how a grease fire starts. One smoking forum user reports losing an entire gas grill and pellet tube setup to a grease fire, and that is not a rare outcome when a tube is placed carelessly.
Set your grill up in two zones: burners on one side, burners off on the other, and the lit tube on the unlit side. Put a drip pan under the grate where your meat sits to protect the unlit burners from rendered fat. Experienced users move flavorizer bars toward the lit side, remove the grate on that side, and use a roasting pan about three-quarters full of water as a crude but effective temperature regulator.
Keep a lid within reach, never leave a lit tube unattended, and do not add pellets to a tube that is already burning. Adding fuel is the fastest way to flare.
Troubleshooting: Why Your Tube Goes Out
The tube dies an hour into the cook. Usually packed pellets or not enough initial burn time. Fill loosely and give it the full burn-off before placing it.
It will not stay lit at all. A standard lighter is rarely enough. Use a propane torch for 30 to 60 seconds and confirm embers are glowing before the flame goes out.
Smoke is white and the flavor is bitter. Two causes. Wet pellets, or the grill is too hot and burning the tube rather than smoldering it. Dry your pellets and drop the cooking temperature.
No visible smoke. The tube may be too far from the food or on a burner that is still running under it. Move it to the unlit side and closer to the food, keeping three inches of clearance.
Pellets spill out of the holes. Fill the tube over the grill and lift rather than slide it when placing.
How to Choose a Smoker Tube for a Gas Grill
Material. 304 stainless steel is the standard here and every tube in this roundup meets it. That number matters because thinner steel dents and 430-grade steel rusts. You do not need to pay more for a grade beyond 304 here.
Length. Twelve inches gives about five hours of smoke and is the right default for a full-size gas grill. Six inches gives around two to 2.5 hours and fits small grills and smoker boxes that a 12-inch tube cannot enter.
Shape. Hexagonal tubes stay put on a slightly angled grate. Round tubes roll, and a rolling tube wastes pellets before you finish the cook. Every product here is hexagonal.
Hole density. This is the variable nobody mentions and it drives smoke output more than any other feature. Densely perforated tubes put out heavier, more even smoke. Sparse holes mean a thin haze that disperses before it reaches your food.
Burn time, realistically. The advertised five hours is a best case measured under ideal conditions. Forum reports on identical tubes range from roughly two to six hours. Plan on three to four as your working number, and know that wet pellets, tightly packed fills and low ambient temperatures all shorten it.
Accessories. A cleaning brush matters within a few cooks. A basting brush and S-hooks are nice rather than essential. A tray that catches ash is worth it if you smoke anything fatty.
How to Clean and Store a Smoker Tube
Maintenance is five minutes of work, and skipping it is how creosote builds up inside a tube and starts tasting bitter into your food.
Let the tube burn out completely with the lid open so the last pellets finish rather than smoldering against your grate. Then set it somewhere heatproof, brush out the loose ash, and clear the hole pattern with the tube brush while it is still warm. A grill cleaning solution and a nylon brush handle the inside; rinse with water and dry fully.
Do not soak it. Trapped water inside a perforated tube causes rust from the inside out, which is the fastest way to ruin 304 stainless.
Store it on the included S-hooks so air circulates, or on the grate in a dry shed if you have no hooks. The discoloration that develops during use is the surface silk burning off. It is cosmetic, it is not a coating that has degraded, and it does not affect safety or flavor.
Frequently Asked Questions
Can you use a smoker tube on a gas grill?
Yes, and that is the main use for these products. Fill a tube with hardwood cooking pellets, light it with a propane torch, burn it openly for three to five minutes, blow out the flame so it smoulders, and place it on the unlit side of the gas grill grate. It produces smoke independent of the burners, so it keeps smoking while you run a two-zone setup.
What is the best smoker tube for grilling?
The LIZZQ Premium Pellet Smoker Tube 12 inch is the best overall for gas grills. It is 304 stainless steel with a hexagonal body that does not roll on the grate, weighs only 8 ounces, and carries the largest review base in our comparison at nearly 15,000 ratings averaging 4.7 stars. The LANNEY 12 inch is the better value if you want brushes and hooks included.
Does a smoke tube make a difference?
It makes a real difference, and on a gas grill it makes the only difference available. A gas grill has no firebox and no wood fuel, so it cannot produce smoke on its own. A tube adds a genuine wood smoke source that runs independently of the burners. Owners report a noticeable bark and flavor shift, though one tube is usually not enough on a full-size grill. Two tubes or a two-tube setup close the gap.
How long does a pellet smoker tube burn?
Advertised claims are about five hours for a full 12-inch tube and two to 2.5 hours for a 6-inch tube. Real-world reports on identical tubes range from roughly two to six hours depending on pellet moisture, how tightly the fill is packed, and ambient temperature. Plan on three to four hours as a working number and treat the stated figure as a best case.
What pellets are best for a smoker tube?
Use food-grade hardwood cooking pellets sold for smoking. Apple and cherry are the mildest and easiest for beginners, hickory is strong and suits pork and brisket, mesquite is the strongest, and oak works as an all-rounder. Never use pellet stove heating pellets, which are not food safe, or loose sawdust, which has no binder and blows out of the tube.
Why is my smoker tube producing white smoke?
White, acrid smoke usually means one of two things. Wet pellets are smoldering instead of burning cleanly, so dry your pellets and keep them in a sealed container. The other cause is a grill running too hot, which burns the tube rather than letting it smolder. Lower the cooking temperature and let the tube settle into a steady smolder.
Final Verdict
The best grill smoker tubes for gas grills are still, after all twelve, the LIZZQ 12 inch for its balance of build quality, weight, and the deepest evidence base we could find. Pick the LANNEY if you want the accessories in the box, the LFSEMINI two-pack if you are cooking a full-size grill for more than a few hours, and a 6-inch tube only if your grill is small enough that a 12-inch one will not fit.
Whichever you choose, the results come down to three things: torch it properly, keep it on the unlit side, and use dry pellets. Burn time claims we checked in 2026 all say five hours, and you should plan for three or four. Start with the LIZZQ, light it on the grate with the lid open, and see how your grill tastes after a full cook.
