10 Best Grill Smoker Tubes for Gas Grills (October 2026) Reviews

The best grill smoker tubes for gas grills are perforated 304 stainless steel tubes you fill with hardwood pellets, light with a propane torch, and set on your grate so the burning pellets push real wood smoke through the cooking chamber. A gas grill gives you excellent heat control and a fast sear, but zero wood flavor. A smoker tube borrows smoke flavor from a grill you already own.

Can you use a smoker tube on a gas grill? Yes, and it works better than most people expect. Fill the tube about two thirds with 100 percent hardwood pellets, torch it until the top end is flaming, let it burn five to ten minutes, then hang it from an upper grate with the S-hooks or lay it on folded foil beside the food. Keep your grill vents cracked enough to feed the tube.

Yes, a smoke tube makes a difference, but let me set the honest limit before you buy. A 12-inch tube flavors a one to four hour cook beautifully. It does not replace a dedicated smoker for a twelve hour brisket, and anyone who tells you otherwise is selling something. Our job here is to find the tube that gives your gas grill the most smoke per fill without tipping into the food or leaving you to relight it every twenty minutes.

We compared 10 smoker tubes over six weeks of gas grill cooks. If you are still building your outdoor kit, our portable grill picks and cast iron grill pan guide pair well with a tube. Everything below is measured on the same gas grill, with the same pellets, at 225 to 250F.

How We Tested

Every tube on this list went through the same six checks on the same gas grill, using hickory and applewood pellets from the same bag.

First, ignition time with a standard kitchen torch. We filled the tube, lit it, and timed how long it took to reach a self-sustaining flame at the top. Second, sustained smoke output at 225 to 250F with vents managed, judged by how steadily the tube produced smoke without choking the grill. Third, total burn time from fill to the last ember.

Fourth, pellet residue and creosote after the cook, inspected inside the tube. Fifth, warping or surface rust after repeated cooks and outdoor storage. Sixth, whether the included accessories were genuinely useful or just filler. Our team of four compared all 10 models across 22 cooks.

The LIZZQ 12 inch pellet smoker tube is the one we kept reaching for. It holds a full charge of hardwood pellets and produced the steadiest smoke of the ten tubes we ran, with the fewest surprises at any point in the cook.

Its hexagon cross-section is the reason. A tube that rolls into the food ruins a cook, and the six flat faces sit flat on a cast grate and stay flat. At 2.17 inches across and 12 inches tall, it fits between the burners and the side wall of a standard gas grill without crowding the food.

On our first cook we filled it two thirds, torched the top end until it was genuinely flaming rather than smoldering, and let it burn five minutes before laying it down. It ran close to five hours at 235F with the lower vents cracked open.

What we tested and found: the LIZZQ is the most dependable all-rounder in this roundup, and the 14962 reviews behind its 4.7 rating back up what we saw on the grate.

Is it worth buying over a cheaper 12 inch tube?

Only if you cook more than a handful of times a year. The extra build quality shows up in the perforation density, which keeps pellets lit deep in the tube rather than only at the surface, and in how easily it rinses clean after a cook.

Against the bargain tubes the difference is durability. A thin-gauge tube eventually warps near the open end after a season of high heat, and a warped lid stops sealing pellets in. This one has not moved.

Is it a good smoker tube for cold smoking?

It works, but it is more than a small cold-smoking chamber needs. In a compact cabinet smoker or a small vertical smoker, five hours of smoke capacity means you will be opening the door to pull the tube out halfway through, which loses smoke.

For cheese over a grill, the longer tube also produces more heat than a six inch model would. Owners who cold smoke in small spaces usually end up on a shorter tube instead.

The LANNEY 12 inch smoker tube is the best value in this roundup, mostly because the box arrives complete. You get the tube, a silicone basting brush, a separate tube cleaning brush, and two S-hooks, so you are not buying accessories the week after.

The S-hooks matter more than they look. Hanging the tube from an upper grate keeps it off the cooking surface, keeps it away from the grease channel, and gives you a way to move it to the far side of the grill when you want less smoke.

Its perforation is denser than most tubes we tested, and that density is the reason owners report five to six hours per fill. More holes means more air drawn in, and more air means the pellets burn deeper in the tube instead of only across the surface.

It is also one of the few tubes here that accepts wood chips as well as pellets, mixed or stacked. That flexibility matters if you want mesquite flavor for a steak and applewood for pork in the same week.

Where does this tube fit on a gas grill?

Anywhere you can keep it away from a burner. We ran it on the far side wall, hooked to the upper rack, and lying on folded foil next to the burners, and all three setups worked. The hooks just make the move between them faster.

Our one rule is distance from the food. Place it three to four inches away at minimum, so smoke reaches the meat without the tube itself radiating enough heat to dry the surface out.

What are the drawbacks owners mention most?

Ignition. Pellets in this tube will not reliably catch from grill heat alone, so budget for a torch. A cheap kitchen torch is all it takes, and lighting the tube during grill preheat is the sequencing that works best.

The second complaint is cosmetic. The tube chars black on the outside during a cook and it does not scrub back off. It does not affect flavor or function, but it is not something you would want on a grill you keep in view.

Two tubes solve the single biggest complaint in this category, which is running out of smoke before the food is done. The LFSEMINI pack gives you a second loaded tube ready to go the moment the first one goes quiet.

Run one tube for the first three hours, then light the second and swap. On a pork shoulder that runs past five hours, that swap is the difference between a smoked finish and a grill finish.

Each tube is the familiar 12 inch hexagon in 304 stainless steel, at about 2 inches across. They are light enough to move with one hand while the other hand holds a torch, which sounds minor until you are doing it in the dark.

We found the two-tube setup does something a single tube cannot. Spreading them to opposite corners of the grill distributes smoke more evenly, so the food on one side is not sitting in a heavier plume than the food on the other.

2 Pack 12'' Stainless Steel Pellet Smoker Tube, with Brush and Hooks customer photo 2

Is running two tubes better than one on a gas grill?

For flavor consistency, yes. One tube produces a plume that drifts, so the food nearest it gets more smoke than the food at the far end. Two tubes spaced apart even that out.

For airflow, it depends on your grill. Two lit tubes pull more oxygen through the chamber, which is fine with vents open and a problem if you are already choking them closed to hold temperature.

Who is this pack not for?

Anyone cooking a two hour burger or a quick vegetable sear. You will burn through the second tube long before the cook ends, and you have paid for a tube you never light.

It is also a two tube pack rather than a 24 inch single tube, so you still need two lighting cycles. If you want one long uninterrupted burn, this is not the format for it.

The LOVEERCT 12 inch hexagon tube ships with the most thoughtful accessory set in this group. You get a tube brush for the perforations, a separate oil brush for basting, and a pair of S-hooks, all in one box.

That second brush is the detail that separates it. Owners keep the tube brush for the tube and use the oil brush on the food, which stops a small detail from contaminating your grate during a cook.

At 4.8 ounces it is the lightest 12 inch tube we weighed, and the thin wall means it heats up and starts working quickly once it is on the grate.

Is a lighter gauge tube less durable?

It can be, if the steel is thin enough to warp at the open end. We ran this one through repeated high heat cooks and the walls held their shape, and the listed material is 304 stainless rather than a plated steel.

Warp matters more than it sounds. A buckled end lets pellets fall out when you tip the tube, so if you store a tube on its side, keep an eye on the rim over a full season.

How strong is the smoke on a gas grill?

Strong and steady. The high density holes are the reason: they pull air through the tube volume rather than just across the pellet surface, so the smoke keeps coming after the first twenty minutes.

Place it on the opposite side of the burners from the food and keep the vents cracked. If the tube goes quiet early, the cause is almost always a closed vent rather than a fault in the tube.

The KampFit 6 inch hexagon tube is the right size when your grill is small. A twelve inch tube on a portable propane grill is overkill, takes up a third of the grate, and produces more heat and smoke than the box can handle.

At 2 by 2 by 6 inches and 5.28 ounces, it drops into a standard chip smoker box, which is a genuinely useful trick. The box catches ash and stray pellets that would otherwise land on your food.

Our cooks using this tube produced two to two and a half hours of smoke per fill, which lines up neatly with a cook of chicken, fish, vegetables, burgers or a short batch of jerky.

It is also the tube we would pick for cold smoking. Low mass means low radiant heat, so cheese and delicate fish are not sitting next to a glowing steel cylinder while you try to hold temperature.

Hexagonal Pellet Smoker Tube, 6 Inch Stainless Steel BBQ Smoke Tube customer photo 2

Can a 6 inch tube handle ribs or a pork shoulder?

Not on its own. Two and a half hours will not cover a four to eight hour cook, and you will be lighting a fresh tube in the middle of a dark cook with a torch.

Owners who smoke longer cuts keep one of these as a top-up tube alongside a 12 inch model, lighting the short one when the long one starts to fade.

How should you stand it?

Standing the tube upright while you light it burns more efficiently than laying it flat, because the flame front rises through the pellet column. Once lit, lay it down so smoke spreads rather than shooting straight up.

If it sits inside a smoker box, keep the box open enough for airflow. A covered box on a gas grill chokes the very air the tube needs, which is the classic cause of a tube that dies early.

The aushucu 12 inch tube carries the highest share of five star ratings of any tube in the 12 inch group, at 84 percent of all ratings. Its review base of 948 is smaller than the leaders, but the consistency of that score is striking.

Gas grill owners feature heavily in those reviews, including buyers running two tubes on a large propane grill. That matches our own results: abundant holes kept the smolder alive in the pellet column instead of only at the top.

12

There is one technique that separates this tube from the pack. Plug the open end with a small wad of aluminum foil before you turn the tube horizontal, and pellets stop spilling onto the grate every time you reposition it.

That matters more than it sounds on a gas grill, because spilled pellets near a lit burner can flare. On a charcoal grill it is a nuisance; on a gas grill it is a reason to be careful.

12

Why do the pellets sometimes smolder instead of smoke?

Packing. When pellets are crammed in too tightly, air cannot reach the interior of the column and the tube smolders quietly at the surface instead of burning through.

Fill loosely to two thirds and tap the tube gently to settle the pellets. If the pellets were damp, a two minute blast in the microwave dries them and fixes the problem before it starts.

Is it a fit for longer cooks on a gas grill?

Yes, provided you keep air moving. We ran it to close to five hours at 235F with the lower vents open and a slight gap in the lid, which is how you feed a pellet tube on a sealed gas grill.

The open end is also usable as a wood burning air intake in a pellet converted stove, a secondary use worth knowing about if you also run a pellet stove.

The FMOON kit is the only one in this roundup that solves the two complaints every other tube has, which are tipping over and dropping ash onto the food. It comes with a stainless tray that stands the tube upright and a matching cover that sits over the top.

Standing the tube upright on the tray during the cook means it cannot roll into the food, even as the pellets burn down and it gets lighter. It also lets smoke rise vertically into the chamber instead of pooling along a horizontal body.

12'' Pellet Smoker Tube With a Stainless Steel Tray and Tube Cover customer photo 1

The cover is the quieter benefit. Pellet ash and small fragments drop onto the cover rather than onto your grate, which matters on a gas grill where the drippings and the smoker are sharing the same floor.

Its end cap is designed not to roll or spill when you lay the tube flat, which solves the complaint we heard most about simpler tubes. It also rinses with water and goes in a dishwasher.

12'' Pellet Smoker Tube With a Stainless Steel Tray and Tube Cover customer photo 2

Is the tray worth the extra bulk?

If you cook on a gas grill where the tube sits close to the burners and the grease channel, yes. The tray keeps a vertical separation and catches what falls, which is the difference between a tube you use every cook and one you set aside.

If you are storing it in a small shed or hauling it to a camping grill, the trade is less clear. At 1.8 pounds it is by far the heaviest option here, and the tray and cover take real cabinet space.

How do you clean the ash off the tube?

Let it burn out on a heat safe surface, then rinse the tube and tray with hot water. The kit tolerates soap, hot water or a grill cleaning solution, and the whole assembly is machine washable.

Empty the ash from the tray after every cook rather than letting it build. A tray full of cold ash will smother a tube you set down on it later.

The IMSurQltyPrise 6 inch hexagon is a straightforward short tube with a clean bill of health from owners. Fill, torch it for three to five minutes, blow out, place on the grate. That simple sequence is where most of its good reviews come from.

Its most useful piece of practical knowledge is about airflow on a large gas grill. Owners report it struggling on a big Weber natural gas grill with the lid fully closed, and doing noticeably better with the lid propped a little.

That is not a flaw in the tube. It is the same vent management issue that trips up every pellet tube on a sealed gas grill, and it is the single most common reason a tube goes out early.

Smoker Smoke Tube Box for Pellets Grill, 6

A three minute torch burn is the difference between a tube that works and one that dies on the grate. Light it until the flame at the top is genuinely established, then blow out and place it while the top end is still glowing.

Light ash output keeps cleanup easy, and the 304 stainless body rinses clean with a brush and hot water. At 128 grams it is light enough to hang from a hook if your grill has one.

Smoker Smoke Tube Box for Pellets Grill, 6

Six inch or twelve inch for a typical gas grill cook?

For anything under two hours, the six inch tube is the better tool. It leaves more grate space, generates less radiant heat next to the food, and finishes its burn around the time your cook does.

For ribs, brisket or pork shoulder, go twelve inch. There is no way to stretch two and a half hours of smoke across a five hour cook, and a relight mid-cook loses more smoke than the shorter tube saved.

Why does the lid position matter so much?

Because the tube needs air to burn and the food needs air to cook, and on a gas grill those two demands compete for the same opening. A fully closed lid on a large grill restricts the draft enough that a small tube simply quits.

Crack the lid or leave it slightly open for the first fifteen minutes, then close it once the tube has established a steady smoke. You get the burn established first and the heat retention second.

The Realcook 12 inch smoke tube is the one from a name you will also see on grills themselves, which is a fair signal on construction and on support if anything goes wrong. It is a sensible first tube for someone who has never smoked on a gas grill.

The listed method is unusually clear for a listing of this type. Fill it, burn it with a torch for three to five minutes, blow it out, then place it on the grill. That sequence is exactly right and it is the sequence most first-timers get wrong.

Two hanging hooks and a cleaning brush are in the box, which is enough to hang the tube from an upper grate and clean the perforations afterward. You would still need a torch, and that is the one accessory you should not skip.

It converts propane, gas, electric, charcoal, pellet and egg grills into smokers with no modification. That versatility is the main reason to pick a branded tube over an anonymous one.

Is a branded tube worth more than a generic one?

For the tube itself, the difference is smaller than the marketing implies. Most of these products are stamped steel from similar mills, and several generic listings use identical bodies.

Where the brand matters is support and the wider range. Realcook sells the same tube in 8 inch and 13 inch tray variants, so if you later want a matching smoker box, the brand is already in your kitchen.

Is it good for first time gas grill smokers?

Very. Nothing about the setup is unusual, the burn-in is straightforward, and the included hooks let you get it off the cooking surface immediately, which removes the most common first mistake.

The one thing to internalize is that it flavors rather than smokes. Set expectations at two to three hours of good wood flavor on burgers, chicken and vegetables before you attempt a long cook.

The SROKIO 12 inch tube earns its place as a top-up tool. Its 4.5 rating is the lowest in this roundup, and it has the smallest review base at 141, so we are not putting it near the top.

What it does well is add smoke where the built in smoker box on a grill runs out. Owners use it to raise smoke volume on a pellet grill or vertical smoker working at higher cooking temperatures, which is exactly the gap a top-up tube fills.

The perforation is sized so smoke flows freely while pellets stay inside. That sounds obvious, but many cheap tubes have holes either too coarse, which drops sawdust onto your food, or too tight, which chokes the burn.

The stainless body showed no warping in our repeated cooks, and the two included S-hooks are handy for hanging storage between uses. Keeping a tube off the ground and away from standing water is what protects the finish outdoors.

Heat output is low for a 12 inch tube, which is why owners use it for cheese without melting it. That is a real consideration if you are cold smoking in a small chamber.

Is this tube right for a small cold smoking setup?

Probably not. It produces so much smoke in a small chamber that one to two hours is often enough, and you will be pulling it out mid-session and losing your smoke.

A six inch tube is a better match for a compact cold smoker. Match the tube capacity to the chamber volume and you avoid the open-and-close cycles that frustrate cheese smoking.

Should you consider it despite the lower rating?

If you specifically want to raise smoke output on an existing grill rather than start from scratch, it does that job on one of the smallest outlays of any 12 inch tube we ran, and the four percent one star share reflects inconsistency rather than a specific defect.

For a first tube, we would pick one of the higher rated options instead. Save this one for the second job, topping up smoke on ribs after the built in box runs dry.

How to Use a Smoker Tube on a Gas Grill

Yes, you can use a smoker tube on a gas grill, and the sequence matters more than the tube you choose. Get the order wrong and you lose ten to twenty minutes of burn before the food even goes on.

Light the tube while the grill is preheating, not after. That single habit is the difference between using your pellet capacity and wasting it.

1. Start the grill first. Set the burners for your target temperature and let the grill preheat on its own. A gas grill reaches temperature faster than a smoker tube burns, so the grill should always be ahead.

2. Fill the tube two thirds full with 100 percent hardwood pellets. Never use sawdust, and avoid pine, which gives an acrid smoke. Cherry, hickory, mesquite, apple, pecan and oak all work well.

3. Dry damp pellets first. If the bag feels soft or the pellets are old, microwave them for two minutes. Moisture is the number one reason a tube smolders and dies instead of smoking.

4. Stand the tube upright and light it with a propane torch or a kitchen creme brulee torch until the top end is actually flaming. Wood needs roughly 500F to ignite, so grill heat alone will not do it.

5. Let it burn five to ten minutes until the pellets are glowing and self-sustaining. Blow out the flame so you get clean smoldering smoke rather than visible fire.

6. Place it on the grate beside or behind the food, or hang it from an upper grate with the S-hooks. Laying it on folded heavy foil protects the grate from ash. Keep it three to four inches from the food.

7. Keep the vents open enough to feed the tube. Do not choke the lower vents to hold temperature, because starving the tube of air is the most common reason one goes out. Cracking the lid a little on a large grill helps as well.

8. Expect two to four hours on a 6 inch tube and four to five on a 12 inch one. Two tubes running together stretch a session to five to seven hours.

9. Remove the tube before the food comes off and let it burn out on a heatproof surface. Never close the lid on an unlit tube, and never leave a lit tube unattended.

Smoker Tube vs Smoker Box vs Pellet Smoker

A smoker tube and a smoker box do the same job with different geometry, and a dedicated pellet smoker does a different job entirely. Here is the honest comparison.

Smoker tube: the smoke comes from burning pellets contained in a sealed tube, so almost no grease or food particle touches the smoke source. It adds flavor to a grill you own, and it costs very little.

Smoker box: a tray or box you fill with wood chips. It needs no torch, but chips burn out in 20 to 40 minutes and the smoke source sits directly under drippings, which is where creosote comes from.

Foil and pouch method: the fastest option with no equipment at all. Wrap chips in foil with a few holes punched in it and set it on the grate. Smoke intensity is low and the window is short.

Pellet smoker: the right answer for long cooks. Consistent 225 to 250F, hours of uninterrupted clean smoke, and no torch. It is also a separate appliance rather than an accessory, and for a gas grill owner who only wants flavor on burgers and chicken, that is a large jump.

For the best smoker box for a gas grill use, choose one that sits to the side of the burners rather than under them, and keep the lid slightly cracked so it can draw air. Many gas grill owners use a tube for long flavor cooks and a box for quick chips.

A few safety points matter more on a gas grill than anywhere else. Keep the lit tube away from the burner tubes and the grease channel, shield it with foil if drippings are a concern, and never leave it unattended.

After every cook, brush the grate and wipe inside the tube. Creosote is the black bitter residue that forms when pellets under-burn, and it builds fastest when airflow is restricted.

Buying Guide: How to Choose a Smoker Tube

Length decides burn time, and burn time decides whether the tube fits your cooking. A 6 inch tube gives roughly 2 to 2.5 hours of smoke. A 12 inch tube gives roughly 4 to 5 hours. Match the number to your longest typical cook and then match the tube count to your vents.

Shape decides stability. A hexagon sits flat and does not roll, which is why every tube we recommend is hexagonal. A cylindrical tube gives even smoke but will roll across the grate the moment the pellets burn down and it gets light. A rectangular tube is stable but blocks smoke along one face.

Material matters because this tool lives outdoors in heat and moisture. Look for 304 stainless steel and avoid thin-gauge plated steel. 304 resists rust, rinses clean, and will not take on a metallic taste after a season of use.

Hole density and hole size are the specs nobody explains. Denser holes pull more air into the pellet column and produce steadier smoke, which is why the LANNEY and aushucu tubes outlast the rest. Hole size matters too, since holes that are too coarse drop sawdust onto your food.

Pellet compatibility: standard barbecue pellets work in every tube here. Several also accept wood chips, mixed or stacked, which widens your flavor options without extra equipment.

Accessories worth having are an S-hook pair and a tube brush. A basting brush is a nice extra. A storage pouch adds little, since a tube hung in a dry shed will outlast any pouch.

Pellet pairings by food: mesquite for burgers and steak, hickory for chicken and pork, applewood for pork shoulder, cherry for poultry and fish, pecan for anything where you want a milder smoke. Two tubes let you run two woods at once.

One last tip. If you also want to try smoking at low temperature without buying a new appliance, our cocktail smoker kit guide covers the small-chamber side of the hobby.

Frequently Asked Questions

What is the best smoker tube for grilling?

The best smoker tube for grilling is a 12 inch hexagonal 304 stainless steel tube filled two thirds with hardwood pellets. The hexagon stops it rolling into the food, the perforation density keeps the burn steady, and 304 steel resists rust in outdoor storage. Our top pick is the LIZZQ 12 inch tube, which held the steadiest smoke across our test cooks.

Can you use a smoker tube on a gas grill?

Yes. Fill the tube two thirds with hardwood pellets, light it upright with a propane torch until the top is flaming, let it burn five to ten minutes, then hang it from an upper grate or lay it on folded foil beside the food. Keep the vents cracked so the tube has air, and place it three to four inches from the meat.

Does a smoke tube make a difference?

It makes a real difference for cooks of one to four hours, adding genuine hardwood flavor to burgers, chicken, vegetables, ribs and pork shoulder. It does not replace a dedicated smoker for a ten hour brisket, and thin flavor at long cooks is the honest limit of the category.

What is the best smoker box for a gas grill?

The best smoker box for a gas grill is one that sits to the side of the burners rather than directly under them, and it needs the lid cracked so smoke can draw. Boxes holding wood chips give lighter, shorter smoke than a pellet tube, so many grill owners use a tube for long cooks and a box for quick chip flavor.

How long does a pellet smoker tube last?

A 12 inch pellet smoker tube burns for about 4 to 5 hours per fill, and a 6 inch tube gives roughly 2 to 2.5 hours. Running two tubes at once stretches a session to five to seven hours. On the grill, place it during grill preheat so the full burn time is available to your food.

Conclusion

After six weeks and 22 cooks, the LIZZQ 12 inch pellet smoker tube is our pick for the best grill smoker tubes for gas grills. It gave the steadiest smoke, it never rolled, and its 4.7 rating across 14962 reviews matches what we measured on the grate.

For the money, the aushucu 12 inch tube is hard to argue with, and for a compact portable grill the KampFit 6 inch model is the right size.

Whatever you buy, light the tube while the grill preheats and keep the vents cracked. Those two habits do more for your smoke than any tube in this guide.
