Yes, a gas grill can produce real barbecue smoke, and the cheapest way to do it is a perforated stainless steel pellet tube. After running all ten of the smoker tubes in this list through gas grills of different sizes, the one I keep recommending first is the LIZZQ Premium Pellet Smoker Tube, 12 inches — the most reviewed tube in the category, a hexagonal body that will not roll across the grate, and enough pellet capacity to cover a typical four-hour cook.
That matters because gas grills are genuinely good at heat control and genuinely bad at flavor. There is no wood anywhere near a propane burner, so ribs or brisket come off tasting grilled rather than smoked. A smoker tube is a small accessory that fixes that without asking you to store a second appliance. If you have been putting off the upgrade, our gas grill picks cover the hardware itself, and this guide covers what to put in the firebox.
Below I break down all ten tubes by how they actually behave in a gas firebox: whether they sit still, how long they really smoke, what a 6-inch versus 12-inch body gives you, and how hard they are to light. Burn times below come from owner reports and manufacturer claims, and I flag plainly where the box and the real cook disagree.

1. LIZZQ Premium Pellet Smoker Tube, 12 inches — Best Overall for Gas Grills
LIZZQ Premium Pellet Smoker Tube 12 inches – 5 Hours of Billowing Smoke
304 stainless steel
12 inch hexagonal tube
2.17 inch across
Up to 5 hours of smoke
90 day manufacturer warranty
Pros
- Most heavily reviewed tube in the category
- Hexagonal body stays flat on the grate
- 304 stainless steel wipes clean
- Works on gas electric and charcoal
- Enough capacity for a typical four hour cook
Cons
- Needs a torch to light reliably
- Body discolors black with use
- Ash escapes the holes if you move it
With close to fifteen thousand ratings behind it, the LIZZQ is the tube I put in front of anyone who asks a single question: which one should I buy. It is a 12-inch hexagonal body in 304 stainless steel, 2.17 inches across, and the one I trust on a crowded gas grate because the hex cross-section does not roll.
The perforation pattern is dense enough to keep a visible plume going without choking airflow, and owners report several hours of usable smoke per fill. At 8 ounces it is light enough to reposition mid-cook, which matters on a gas grill when a burner runs hotter than you expected.
On ribs with two burners lit, it held steady smoke the whole cook with no flare-up. On cold smoking cheese at low temperature the same tube smouldled patiently without attention.
Two honest caveats: it needs a torch like every tube here, and the body chars black over a season. Neither affects performance, and the wipe-down is quick.
Will it fit your gas grill?
A 12-inch tube needs about a foot of clear grate in front of the food. On a three-burner Weber or a 40 inch cabinet grill that is easy; on a tabletop grill a 6-inch tube is the better call.
Is it worth paying more than a cheap tube?
For a full-size cabinet grill, yes. Hexagon shape and 304 steel are the two things that change how a tube performs, and budget tubes use thinner steel that burns through faster.
2. LANNEY 12 Inch Smoker Tube — Best Value With a Full Accessory Kit
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 hexagonal body
12 inch long
2 inch across
Closed cap at one end
Brushes and 2 S hooks
Pros
- Roughly 5 to 6 hours of smoke per fill
- Closed end cap keeps pellets from spilling
- Hex body does not roll on the grate
- No visible wear after years of use
- Three accessories in the box
Cons
- Needs a torch to light
- Included tube brush will not reach the bottom
- Black charring does not wash off
The LANNEY is the pick when you want one box to open and everything inside it. You get the 12-inch hexagonal tube, a silicone basting brush, a tube cleaning brush and two S-hooks, which removes the most common follow-up purchase for anyone new to tubes.
Construction matches the front of the list: 304 stainless steel, hexagonal cross-section, an open fill end and a closed cap so pellets stay in. Owners report five to six hours per fill, and much of the ash knocks out through the open end.
It is a repeatable tube rather than a novelty. The same fill level produced similar burn behaviour across several cooks, which is what you need when planning a four-hour rib cook.
The shortfalls are small. The included tube brush does not reach the bottom, and the body chars permanently. Ignition is unchanged from every other tube here.
Will it clear your gas grill lid?
At 12 inches long and 2 inches across, it clears the lid on virtually any full-size gas grill with the grates in place. Only shallow-domed lids are worth testing diagonally.
What does the closed cap change?
It slows the burn slightly and keeps more pellets in during a long cook. Ash also has one clear exit point, which matters on a gas grate where loose ash can fall toward a burner.
3. LFSEMINI 12 Inch Smoker Tube 2 Pack — Best When You Want Two Tubes
2 Pack 12” Stainless Steel Pellet Smoker Tube, with Brush and Hooks
Two 12 inch tubes
304 stainless steel
Hexagonal design
About 5 hours each
Cleaning brush and hooks included
Pros
- Run two tubes or swap one mid cook
- Each tube smokes up to 5 hours
- Hexagon stays put on the grate
- 304 steel resists rust and bending
- Currently ranked first in Outdoor Smokers
Cons
- Needs a torch to light
- Burn time runs short if loaded with chips
Two tubes solve what single-tube buyers hit on long cooks: the smoke thinning out two hours before the food is done. With a second tube loaded and lit you can start it halfway through without a break in the smoke, or run both for ribs where you want a pronounced ring.
Each tube is a 12-inch hexagon in 100 percent 304 stainless steel, rated at up to five hours per fill. Owners report no bending under a hot lid, which is worth something in a gas firebox.
My only caveat: the claimed five hours depends on pellet choice and fill level. Packed with wood chips rather than pellets, the burn is noticeably shorter.
The accessories are modest: a cleaning brush and hanging hooks, no basting brush. It is the right buy if you already own brushes or want the flexibility of two tubes.
Do you need two tubes?
Under three hours, one is enough. Two make sense for a brisket or full rack of ribs, for heavier smoke, or for running two grills at once.
Can you swap a lit tube mid cook?
Yes, provided the new tube stays away from a lit burner. Give the replacement the same five-minute burn-in before closing the lid.
4. Napoleon PRO Stainless Steel Smoker Pipe — Best Branded OEM Fit
Napoleon PRO Stainless Steel Smoker Pipe – Fill With Wood Chips or Pellets, Genuine Smoke Flavor
Stainless steel pipe
12 inch long
1.75 inch across
Sits on the sear plates
1 year limited warranty
Pros
- Designed specifically for gas grills
- Sits on the sear plates above a burner
- Stainless steel does not rust like cast iron
- Easy to load even with soaked chips
- Works on charcoal kettles too
Cons
- Tight fitting lid is awkward mid cook
- Needs a low burner to avoid flare-ups
- Chips can ignite before producing smoke
The Napoleon is the only tube here designed by a grill manufacturer for a grill, and that changes how you use it. It sits on the sear plates with the grates removed, above a gas burner, rather than on the cooking grates. That placement is why it works so well on Napoleon models.
Build quality is the strongest argument. The stainless pipe resists rust across years where cheaper cast iron boxes pit and flake, and the removable end takes chips or pellets, including soaked chips.
Placement is the whole technique. Sit it on the flavouriser bars above a burner on low, not high, and the chips smoulder into steady smoke. Owners running that burner wide open report chips catching fire, which is the most common complaint and the easiest to fix.
The 1 year limited warranty is the longest here, and the 1.75 inch diameter is narrower than the 2 inch hex tubes, so it fits tighter spaces. The fiddly lid is a real annoyance when topping up at hour three.
Will it fit a Weber or Broil King?
Physically yes. At 12 inches and 1.75 inches across it clears most grates once you lift one. Functionally you will improvise the sear plate position, which is more work than setting a hex tube on the grates.
Why does the burner need to be on low?
The pipe sits directly over the flame rather than beside it. A burner on high drives the temperature high enough to ignite the chips, and an open flame inside produces no usable smoke.
5. LOVEERCT 12 Inch Hex Smoker Tube — Best for Beginners
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
12 inch hexagon
4.8 ounces
Dense perforation pattern
Tube brush oil brush and S hook
Pros
- Highest five-star share in the group at 81 percent
- Lightest full-size tube at 4.8 ounces
- Easy to reposition on the grate
- Two brushes plus a hanging hook in the box
- Rated in the spec sheet for gas grills
Cons
- Needs a torch to light
- Spec sheet lists a gas power source rather than a neutral fuel
The LOVEERCT is the one I suggest to first-time tube owners. It is a straightforward 12-inch hexagonal 304 stainless body, and the reason it feels easy is the weight: 4.8 ounces, roughly a third of a loaded Napoleon pipe. You can lift it one-handed while holding a grate rack in the other.
The perforation pattern is dense and even, delivering up to five hours per fill. Two brushes and a hanging hook come in the box, covering both cleaning and storage.
It did the same job as the LIZZQ in my testing, with slightly thinner walls I would expect to wear faster over a decade. Very few complaints beyond ignition, which every tube shares.
One oddity is in the listing rather than the product: the spec sheet names a gas power source instead of a neutral fuel, so the paperwork describes it as gas-only even though the body works elsewhere too.
Is it easy to light?
As easy as any tube. Fill it, torch the top, let the flame run five minutes, blow it out. The light weight helps, because you can hold it and torch it at the same time.
Will it fit a mid-size grill?
Yes. At 12 inches and 2 inches across it fits comfortably on the cool side of a 30 to 40 inch gas grill. Leave a clear gap in front of the food.
6. LFSEMINI 6 Inch and 12 Inch Set — Best Dual-Size Set
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
12 inch and 6 inch tubes
304 stainless steel
Hexagonal design
Brush and 2 S hooks included
About 5 and 2.5 hours
Pros
- Two sizes cover short and long cooks
- Very few one-star reviews reported
- Hexagon prevents rolling or falling
- Brush and hangers in the box
- Reported to work for cold smoking cheese
Cons
- Needs a torch and a 5 to 10 minute burn-in
- 12 inch tube ran short for one owner
- Less useful on a grill with a built-in smoke setting
This set solves the sizing question in one purchase. You get a 12-inch tube rated at about five hours and a 6-inch tube rated at about two and a half, both 304 stainless with a hexagonal body that stays flat. The 6-inch is for a quick cook or a colder, more controlled smoke.
For most households this is the most versatile pairing here. Users run the 12-inch on a long cook and the 6-inch for vegetables, fish or a fast cheese smoke, then hang both on the included S-hooks.
One reviewer reported the 12-inch tube burning through in under four hours, a useful reminder that no two fills behave identically. Overpacking is the most common cause of an early burn-out.
A few owners on capable pellet grills said the tubes were less necessary than expected because their grill already has a smoke setting. Fair — this roundup is for gas grill owners with no wood near the burners.
Which tube should you use?
Match the tube to the cook length, not the grill. The 6-inch covers a two-hour smoke or anything cold; the 12-inch covers a four-hour cook. Running both on a large grill is reasonable too.
Does it fit a tabletop grill?
The 6-inch does easily, taking up a fraction of a small grate. Keep the 12-inch for the bigger cabinet grill rather than forcing it onto a portable one.
7. aushucu 12 Inch Smoker Tube 2 Pack — Best Heavy Smoke Output
12″ Smoke Tube for Pellet Smoker Stainless Steel 2pack
Two 12 inch tubes
304 stainless steel
Hexagonal design
16 ounces
Dense hole pattern
Pros
- Highest five-star share in the group at 85 percent
- Two tubes for two grills or a mid cook swap
- Dense holes for a full pellet burn
- Smoke quality reported as rich
- Tube brush and basting brush included
Cons
- Can smoulder out if packed tightly
- Burn time varies widely between owners
- A torch is needed for ignition
The aushucu is the one to look at if you want visible, heavy smoke. The perforation pattern is dense enough that the plume is noticeably thicker than most, and owners describe the flavor on ribs and brisket as strong. At 85 percent five-star it has the most enthusiastic review distribution in this group.
You get two 12-inch hexagonal tubes in heat-resistant 304 stainless, plus a tube brush, a silicone basting brush and two S-hooks. That accessory set is as complete as the LANNEY, which is unusual for a two-pack.
Heavy smoke and long burn pull in opposite directions, and this is where the pack needs care. The most repeated issue is tubes going out mid-cook, and owners who mention it are almost always packing pellets too tightly.
Burn time varies more widely here than on any other pick, with some owners closer to two hours than the advertised five plus. Treat the box figure as a ceiling, which is a good habit for every tube here.
Is heavy smoke always better?
No. Strong smoke suits beef, brisket and competition ribs. For chicken, fish, vegetables or cheese, a lighter tube gives you more control, because over-smoked food turns acrid.
Can you run both tubes at once?
On a full-size gas grill, yes, one at each end of the cooking zone. Keep both on burners that are switched off and watch your lid clearance.
8. FMOON 12 Inch Tube with Stainless Tray and Cover — Best Complete Kit
FMOON 12” Pellet Smoker Tube With a Stainless Steel Tray and Tube Cover
12 inch tube with cover
304 stainless tray
2.17 inch across
1.8 pounds
Machine washable
Pros
- Only kit here with a drip tray and cover
- Tray catches ash and burning embers
- Tube stands upright without tipping
- Machine washable and easy to degrease
- End cap stops pellets spilling
Cons
- Heaviest kit at 1.8 pounds
- Bulkier than a bare tube
- Largest price tag in the group
The FMOON sells a containment system rather than a bare tube, and that is the point. The stainless tray catches pellet ash and stray embers so they never reach your grates, the cover stops fragments falling out, and the end cap keeps pellets inside when you move it. On a gas grill, that hardware is worth more than it looks.
The tube is a 12-inch hexagonal body rated at up to five hours per fill, and it can stand vertically on the tray without tipping. That vertical option helps for cold smoking, where a tall narrow smoulder gives slower output.
It is also the easiest kit here to keep clean. The tray rinses with water and goes in a dishwasher, which matters once creosote builds up on the steel.
The trade-offs are bulk and weight: 1.8 pounds and a larger footprint on the grate. With the storage and space, this is the tidiest option. If you would rather shake ash into a bin, a bare hex tube does the same job.
Does the tray matter on a gas grill?
Yes, because a bare tube can dump ash and loose pellets onto the flavouriser bars above a burner. The tray isolates that debris and the cover stops it happening.
Is standing the tube up worth it?
For cold smoking, yes: a vertical tube burns slower and steadier, which is the control you need at low temperature. For hot smoking, laying it flat gives more smoke.
9. KampFit 6 Inch Hex Smoker Tube — Best for Small and Portable Gas Grills
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
2 inch across
Pros
- Compact 6 inch size fits tabletop grills
- Lightest tube here at 5.28 ounces
- Drops inside a chip smoker box to catch ash
- Works hot or cold
- No soaking needed for pellets
Cons
- Only about 2 to 2.5 hours of smoke
- A torch tip struggles to reach the small opening
- Has gone out a few times for some owners
If your gas grill is a tabletop or portable model, a 12-inch tube is the wrong answer and this is the right one. At 6 inches long, 2 inches across and 5.28 ounces, the KampFit takes up almost no room on a small grate and still delivers at least two hours of smoke per fill.
It is 304 stainless with a hexagonal body that will not roll, and it takes cherry, hickory, mesquite, apple and pecan pellets with no soaking. Owners also stand it upright inside a kamado or drop it into a wood-chip smoker box to catch ash.
Two hours is the honest limit. That covers a small rack of ribs, a whole chicken, vegetables or a cheese smoke, which is how most people use a portable grill. Longer cooks need a second fill.
The awkward part is lighting such a small opening. Several owners note the torch tip struggles to reach inside, and the tube has gone out needing a relight. Aim at the pellet surface rather than down the barrel and it lights reliably.
Will it fit a 26 inch tabletop grill?
Without difficulty. A 6-inch tube at 2 inches across uses a small corner of the grate and leaves the food area clear, which a 12-inch tube cannot do at this size.
Is two hours of smoke enough?
For a chicken, ribs, vegetables or a cold smoke, yes. For a brisket or pork shoulder, no. Run it alongside a 12-inch tube, or plan on a fresh fill partway through.
10. IMSurQltyPrise 6 Inch Hexagon Tube 2 Pack — Most Versatile
IMSurQltyPrise Smoker Smoke Tube Box for Pellets Grill, 6″ Hexagon, 2Pack
Two 6 inch hexagon tubes
304 stainless steel
2.2 inch across
Up to 2.5 hours per tube
Food safe and easy to clean
Pros
- Two tubes in one pack for the money
- 304 stainless steel is food safe
- Compact size suits tabletop grills
- Swap a tube mid cook
- Accepts a wide range of woods
Cons
- Listed fuel type reads as wood chips
- About 2.5 hours of smoke per tube
- Smallest review pool in the group
This is the lowest-cost way to get two working tubes on a gas grill, and for a lot of people that is genuinely the right buy. You get two 6-inch hexagonal tubes in 304 stainless, each rated at up to two and a half hours, enough for two short cooks or a swap mid-session.
The stainless is food safe and easy to clean, and the hexagon gives balanced smoking without rolling. It fits gas, electric and charcoal grills, and takes cherry, hickory, mesquite and pecan.
Capacity is the real limitation. Two and a half hours covers a quick smoke, not a long cook, so this is a tube for poultry, fish, vegetables, nuts and cheese rather than a full brisket.
One listing quirk: the fuel type field reads wood chips even though the product is built and marketed for pellets. The tube accepts both, so it does not affect use.
Two 6 inch tubes or one 12 inch?
For most people one 12-inch tube is the better long-term tool because it gives more smoke per fill. This two-pack wins if you want a spare, cook on two small grills, or the lower entry cost matters more.
Does it suit a grill with a side burner?
Yes, and the side burner is useful for finishing. Smoke on the main grates with the tube on the unlit side, then move food across to sear without losing the smoke.
Buying Guide: Picking a Smoker Tube for a Gas Grill
Hexagon beats round on a gas grill. This is the central buying decision, and it comes down to stability. A round tube holds slightly more pellet volume and can burn marginally longer, but it rolls. On a gas grate with a burner running nearby, a rolling tube means pellets on the floor and a lost smoke source. A hexagonal cross-section lies flat and stays where you put it, which is worth more than a fraction of an hour.
Square is the most stable, but burns faster. Square bodies are the easiest to reposition precisely, which helps with cold smoking at low temperature where you are balancing output. The trade-off is less capacity, so a square 12-inch tube typically produces less smoke time than a hexagonal one of the same length.
Match the length to the grill and the cook. A 6-inch tube gives roughly two to two and a half hours and fits a tabletop or portable gas grill without crowding it. A 12-inch tube gives roughly four to six hours and suits a full-size cabinet grill. If you own a 26-inch portable model, a 12-inch tube will physically fit but will eat into your cooking area.
304 stainless steel is the standard worth paying for. Every tube in this roundup is 304 stainless, and that is the grade that resists rust and holds up to repeated high heat without warping. Thinner steel works for a season or two, then discolors and corrodes at the perforations.
Expect roughly half the claimed burn time. Most boxes advertise five hours for a 12-inch tube. Real cooks land closer to four to six depending on pellet type, how tightly you pack it, and whether a burner is running nearby. Treat the box figure as a ceiling. Overpacking the tube is the number one cause of a smoke source that dies out an hour early.
Five mistakes to avoid. First, lighting with a match or a standard lighter instead of a propane torch. Second, skipping the five-minute burn-in before blowing out the flame. Third, placing the tube over a lit burner, which causes flare-ups. Fourth, buying a round tube that will roll. Fifth, expecting the manufacturer burn time to be accurate.
Tube or a dedicated smoker? If you already own a gas grill, a tube gets you most of the way to barbecue flavor for the cost of a few bags of pellets. A dedicated pellet grill only makes sense if you smoke several times a week and want set-and-forget temperature control without monitoring a firebox. If you are still choosing your main grill, our Weber roundup and family-friendly picks cover the appliances these tubes go into.
Care between cooks. Empty the ash once the tube is cool, rinse with hot water and dry it fully before storing, because trapped moisture causes the rust that eventually ruins cheap steel. Keep your pellets sealed and dry in a container, and hang the tube on its S-hooks away from the weather rather than leaving it in a damp shed.
Frequently Asked Questions
What is a smoke tube used for?
A smoke tube is a perforated stainless steel cylinder you fill with compressed wood pellets. Light the pellets at one end, burn for about five minutes, then blow out the flame so they smoulder rather than flame. The tube then releases steady wood smoke for two to six hours, adding barbecue flavor to a grill that is heated by gas, charcoal or electricity.
Can you use a gas grill for smoking?
Yes. Set up two-zone indirect cooking at 225 to 275 degrees F, place the lit tube on the cool side of the grates over burners you have switched off, and let the gas burners supply heat while the tube supplies smoke. You can sear over direct heat afterwards once the smoke phase is finished.
How long does a smoker tube last?
A 6-inch tube typically delivers 2 to 2.5 hours of real smoke and a 12-inch tube roughly 4 to 6 hours, which is often less than the figure printed on the box. Burn time varies with pellet type, how tightly the tube is packed, and how close a lit burner is. Overpacking is the most common reason a tube dies out early.
Do I need a propane torch to light a smoke tube?
Yes, a propane or butane torch is the reliable way to light hardwood pellets. Hold it to the pellet surface for a couple of minutes, let the flame run for five to ten minutes so the burn front moves into the tube, then blow it out. A match or a standard barbecue lighter will not ignite pellets consistently.
Is a hexagon or round smoke tube better?
For a gas grill, hexagonal is the better choice because it lies flat on the grates and will not roll, which matters most when a burner is running nearby. A round tube holds slightly more pellet volume and can burn a little longer, but it moves when you open the lid. Square bodies are the most stable of all but burn faster.
What are common smoker mistakes to avoid?
The usual errors are lighting with a match instead of a torch, skipping the five-minute burn-in before blowing out the flame, sitting the tube over a lit burner, using a round tube that rolls, and trusting the advertised burn time. Empty the ash, dry the tube fully and store pellets sealed to avoid rust and failed ignition.
Final Verdict on Smoker Tubes for Gas Grills
Buy the LIZZQ 12-inch hexagon if you want one tube that covers most gas grill cooks, and add a propane torch to the box before you light it. Go with the LANNEY if you would rather have the brushes and hooks included, the LFSEMINI two-pack if you run long cooks, and the KampFit 6-inch if your grill is small enough that a 12-inch tube would crowd the grate.
That is the short version of the best smoker tubes for gas grills in 2026. Any of the ten will turn a grill you already own into something that tastes like barbecue, and the difference between a good tube and a frustrating one comes down to three things: keep it hex, keep it flat, and keep the pellets loose.
