A pellet smoker tube is one of the cheapest upgrades you can make to any grill, and it might be the one that changes how your food tastes the most. Drop a few tablespoons of hardwood pellets into a perforated stainless steel tube, light one end, and you get hours of clean, billowing smoke on a gas grill, a charcoal kettle, an electric smoker, or even inside a pellet grill that is already running. It is real wood smoke with no extra fuel to manage and no expensive equipment to buy.
The reason we love these little tubes is how flexible they are. Set your grill up hot and the tube layers extra smoke onto ribs, chicken, and brisket. Skip the burners and the same tube becomes a cold smoke generator for cheese, salmon, nuts, and bacon. If you already own a pellet smoker, a tube still earns its keep by boosting smoke on low-and-slow cooks where the auger runs clean. Pair one with quality wood pellets and you have a flavor tool that costs less than a couple racks of ribs.
We dug through specs, owner feedback, and years of common complaints to sort the tubes that light easily and stay lit from the ones that sputter out. Below are the six tubes and maze smokers we think are worth your money, plus a plain guide to shapes, lighting, and smoke.
A tube is also the fastest way to add real smoke to a quick cook, not just an all-day one. If you are grilling plant-based burgers or sausages for a vegetarian or vegan guest, see our guide on how to smoke Beyond Meat for the short, hot method that fits a four-minute cook.

The 6 Best Pellet Smoker Tubes, Reviewed
The LIZZQ Premium 12 Inch Tube Is Our Top All Around Smoke Tube
The LIZZQ Premium is the tube we would hand a friend buying their first one. It is a 12 inch hexagonal tube made from 304 stainless steel, and the six flat sides are the whole point. A hexagon will not roll off the grates when you set it down or bump the lid, which sounds minor until you have chased a round tube across a hot grill. Packed full, owners consistently report right around five hours of steady smoke, enough for most low-and-slow cooks and plenty of cold smoking.
It works the same on a gas grill, a charcoal kettle, an electric smoker, or inside a running pellet grill. The perforations are sized to keep pellets smoldering rather than flaming, so once you get it going it tends to stay going, and LIZZQ usually bundles a silicone basting brush.
Pros
- Hexagon shape stays put
- Solid stainless build
- About five hour burn
- Great hot and cold smoking
- Works on any grill
Cons
- Needs careful torch lighting
- Not for all-day cold smoke
The verdict: Buy it if you want one tube that does everything well and forgives a little sloppiness. Skip it if you specifically need all-day cold smoke, in which case a maze will serve you better.
The A-MAZE-N AMNPS Maze Runs Longer Than Any Tube For True Cold Smoking
When people talk about smoking cheese, salmon, or bacon for the better part of a day without any heat, this is usually the product they mean. The A-MAZE-N AMNPS is a 5 by 8 inch maze rather than a tube. Pellets sit in a winding S-shaped channel, and the burn slowly follows the maze from one end to the other. Because the fire only advances along that narrow path, a single fill can produce smoke for up to about 11 hours, far longer than any 12 inch tube.
That long, low output is exactly what cold smoking wants. It sits flat on the grate, throws very little heat of its own, and sips pellets. A-MAZE-N is one of the original names in this category, and the reputation is earned. The trade-off is that a maze is fussier to light and keep lit than a tube, and it rewards dry pellets and a little patience.
Pros
- Longest runtime up to 11 hours
- Purpose built for cold smoking
- Gentle smoke for delicate foods
- Sits flat and throws little heat
- Sips pellets
Cons
- Fussier to light than tubes
- Needs very dry pellets
- Requires patience
The verdict: Buy it if cold smoking cheese, fish, and cured meats is your main goal. Skip it if you mostly want a quick smoke boost on hot cooks, where a tube is simpler.
The A-MAZE-N AMNTS12 Is The Original Name Brand Tube Worth Trusting
If you like the A-MAZE-N pedigree but want a tube instead of a maze, the AMNTS12 is the answer. It is a 12 inch oval stainless steel tube that works for both hot and cold smoking on any grill or smoker. The oval cross section is a smart middle ground. It has a flat bottom so it will not roll like a fully round tube, while keeping the simple fill-and-light routine that makes tubes so easy.
Expect around four hours of smoke from a full load. Owners tend to praise the consistency, and because A-MAZE-N built its name on smoke generators, the tolerances and perforation sizing feel dialed in. It costs a little more than the no-name tubes, and that premium buys you a known quantity.
Pros
- Trusted brand quality
- Oval shape resists rolling
- Reliable smoke output
- Works hot and cold
Cons
- Shorter runtime than hexagons
- Costs a brand premium
The verdict: Buy it if you want a name you can trust and a shape that behaves. Skip it if a budget hexagon will do the same job for less.
The Skoo Hexagonal Tube Delivers Steady Smoke Without Breaking The Bank
The Skoo is our value pick, and it does not feel like a compromise. It is a 12 inch hexagonal stainless steel tube that, like the LIZZQ, uses its flat sides to stay planted on the grate. A full fill gives you up to about five hours of smoke, and Skoo sweetens the deal by including a cleaning brush and an S hook in the box, plus a recipe eBook for people just getting started.
What stands out is how little you give up to save money. It lights the same way, holds a similar volume of pellets, and produces the same thin, steady smoke. The accessories mean you can hang it to cool or scrub out ash without buying anything extra. For a lot of backyard cooks, this is all the tube they will ever need.
Pros
- Strong value price
- Full accessory kit included
- Practical hexagon shape
- About five hour burn
Cons
- Fit and finish is basic
- Needs careful lighting
The verdict: Buy it if you want maximum smoke per dollar and a kit that is ready to use. Skip it if you prefer paying up for a marquee brand.
The Carpathen Smoke Tube Is Built For Low And Slow Cold Smoking
Carpathen leans hard into cold smoking, and the marketing is honest about it. This is a 12 inch round stainless steel tube built to billow cool smoke for up to about five hours, aimed squarely at cheese, fish, pork, beef, and nuts. If your dream is a tray of cold smoked cheddar or a side of salmon, it is set up for exactly that low, gentle output.
The one thing to keep in mind is the shape. A round tube can roll, so most owners lay it against a grate edge. It still works fine on hot cooks, but the sweet spot is unheated smoking on a cool day, when ambient temperature matters as much as the tube itself.
Pros
- Built for cold smoking
- Generous five hour burn
- Clean smoke for cheese and fish
Cons
- Round shape can roll
- Best only in cool weather
The verdict: Buy it if cold smoked cheese and fish are on your menu. Skip it if a flat sided tube that stays put matters more to you than the cold smoke branding.
The Kampfit 6 Inch Tube Fits Small Grills And Shorter Cooks
Not every cook needs five hours of smoke, and not every grill has room for a foot long tube. The Kampfit 6 inch is a compact perforated stainless steel tube that fits neatly on a charcoal kettle or small gas grill. A full load gives you roughly two hours of smoke, right for a batch of wings, a few chicken breasts, or a quick cheese session.
The smaller size is also easier to light, since there is less pellet to ignite, and it handles both hot and cold smoking across electric, gas, and charcoal setups. If you already own a 12 inch tube, a small one like this is a handy second unit for shorter cooks.
Pros
- Compact fits small grills
- Lights quickly
- Good for shorter cooks
- Handy second tube
Cons
- Only about two hours
- Round shape can roll
The verdict: Buy it for a small grill or a quick smoke without a full tube. Skip it if you run all-day cooks and need maximum runtime.
How to Choose a Pellet Smoker Tube
Hexagon vs Round vs Maze
Shape matters more than most people expect. Round tubes are the cheapest and most common, but they roll, and a tube that rolls tips pellets and can dump ash. Hexagonal tubes solve that with flat sides that keep them planted, which is why two of our top picks are hexagons. Oval tubes split the difference with a flat bottom and rounded top.
Mazes are a different animal. Pellets fill a winding channel and the fire creeps along it slowly, which is what lets a maze run up to 11 hours while a 12 inch tube tops out around five. If your priority is long, cool cold smoking, a maze wins. For a simple grab-and-go smoke boost on the grill, a tube is easier to live with.
How to Light and Use a Smoke Tube
Getting a tube lit correctly is the whole game, and it is where most complaints come from. Fill the tube with dry pellets, stand it upright, and hit the top with a butane or propane torch, since a regular lighter usually is not enough. Let it flame for a solid two to three minutes until you have a strong, glowing ember, then blow the flame out so the pellets smolder. You want thin blue smoke, not thick white billows.
Set the lit tube on the far side of the grates, away from your food if you can, and leave the lid vents open a crack so the smoke has somewhere to go. If the tube keeps going out, the culprit is almost always damp pellets, too little airflow, or a weak ember, so give it more torch time and keep your pellets dry.
Cold Smoking vs Hot Smoking and Which Pellets to Use
Hot smoking means your grill is running at normal temperatures and the tube just adds wood flavor on top. Cold smoking means no burners at all, so the food never really cooks and only takes on smoke, which is how you handle cheese, cured salmon, and nuts. It works best on a cool day, since a hot afternoon can soften cheese even without the grill lit, and a pan of ice near the food helps.
For pellets, use 100 percent hardwood pellets made for smoking, not heating pellets, which can contain fillers you do not want near food. Match the wood to the food. Milder fruit woods like apple and cherry suit cheese, poultry, and fish, while hickory and oak stand up to beef and pork. Keep the pellets bone dry, since moisture is the enemy of a steady burn.
Frequently Asked Questions
How long does a pellet smoker tube last on one fill
It depends on size and shape. A 12 inch tube packed full typically runs four to five hours, while a short 6 inch tube gives you closer to two. A maze smoker like the A-MAZE-N AMNPS can stretch to around 11 hours because the fire follows a long winding path instead of a straight tube.
Do I need to soak the pellets first
No, and you should not. Soaking pellets turns them to mush and makes the tube nearly impossible to keep lit. Pellets need to be dry to smolder properly, so store them sealed and dry. Wet or stale pellets are the most common reason a tube goes out.
Can I use a smoke tube in a gas grill
Yes, and it is one of the best uses for a tube. Gas grills make heat but almost no smoke flavor, so a lit tube fills that gap. Set it on the grates, light it fully first, and you get real wood smoke on a grill that normally cannot make any.
Why does my smoke tube keep going out
Three usual suspects. First, the ember was never fully established, so torch the pellets for two to three minutes before blowing out the flame. Second, damp pellets will not sustain a burn, so use dry ones. Third, the tube needs airflow, so make sure your grill vents are open enough to feed the smolder some oxygen.
Are hexagon tubes really better than round ones
For most people, yes, mainly because they do not roll. A round tube can shift on the grate, spill pellets, or tip ash when you open the lid, while a hexagon sits flat and stays put. The smoke itself is the same, so the advantage is purely stability and convenience, but that convenience is real.
Our Pick for Most People
If you want one tube that does nearly everything, get the LIZZQ Premium 12 Inch. The hexagon shape keeps it from rolling, the 304 stainless build feels solid, and the roughly five hour burn covers hot cooks and cold smoking alike. To spend less without giving up much, the Skoo hexagon is a genuine bargain with a full accessory kit. And if your real goal is long, cool cold smoking for cheese and fish, step up to the A-MAZE-N AMNPS maze for its all-day runtime. Any of the three adds real wood smoke to your backyard for less than the price of dinner out.
