A pellet grill’s biggest strength — a clean, tightly controlled fire — is also why it can taste less smoky than a stick burner, especially above 300°F. A smoke tube fixes that by burning its own pellet charge independent of the grill’s auger, adding smoke on demand whether the grill is running hot or completely off. We compared the tubes and mazes worth buying in 2026 on burn time, shape, and what each one is actually built for.
Quick Answer
The LIZZQ Premium Pellet Smoker Tube, 12” is the best all-around pick — hexagonal 304 stainless steel that won’t roll off the grate, with a manufacturer claim of 5 hours of smoke per fill for hot-and-fast cooks that need a smoke boost. For long cold-smoking sessions like cheese or nuts, the A-MAZE-N AMNPS 5x8 maze is the better tool: its switchback tray design is rated for up to 12 hours versus roughly 4 hours for a straight 12” tube, because the smolder travels a longer path. Both burn standard food-grade hardwood pellets — the same ones you’d load into your hopper — not pellet-stove heating pellets or loose sawdust.

LIZZQ is the tube most pellet-grill owners land on first, and the hexagonal shape is the reason: a round tube rolls the second your grill isn’t perfectly level, and most grates aren’t. Fill it snugly (not compressed) with hardwood pellets, torch one end for 30-60 seconds until it catches, let it burn with an open flame for about 5 minutes, then blow it out so it smolders. The 5-hour claim is the manufacturer’s ceiling — real-world reports on forums like Smoking Meat Forums range from roughly 2 to 6+ hours depending on pellet moisture and airflow around the tube, so treat it as “most of a long cook,” not a guarantee you can set and forget past dinner.
2. A-MAZE-N AMNTS 12 Tube Smoker — Best From a Dedicated Smoking Brand
A-MAZE-N AMNTS12 Oval Tube Smoker
- Made by A-MAZE-N, a brand that builds nothing but cold- and hot-smoking accessories.
- Oval profile, expands for loading and compresses back down for a snug pellet pack.
- Rated by the manufacturer for roughly 4 hours of smoke — shorter than LIZZQ's claim, reflecting the smaller fill volume.
- Regular price around $21, per current retail listings.
A-MAZE-N built its reputation on the maze/tray design below, but its tube line is worth knowing about specifically because it’s a shorter, hot-cook-oriented burn rather than an attempt to match LIZZQ’s 5-hour claim. If your typical use case is adding smoke to a 2-3 hour hot-and-fast cook rather than a full overnight brisket, the shorter fill is a feature, not a shortcoming — it’s less unused fuel left in the tube when the cook is done.
3. A-MAZE-N AMNPS 5x8 Maze — Best for Cold Smoking
A-MAZE-N AMNPS 5x8 Pellet Maze Smoker
- Switchback maze tray, not a straight tube — the S-pattern burn path is what unlocks the long runtime.
- Manufacturer-rated for up to 12 hours, roughly 3x a straight tube's claimed burn.
- The standard cold-smoking tool for cheese, nuts, salt, and bacon — grill stays off entirely.
- Street price commonly runs $23-$35 depending on retailer and current promotions.
This is the tool for a genuinely different job than the tubes above. A straight tube is built to add smoke while the grill is otherwise running or briefly off; the AMNPS maze exists so you can cold-smoke cheddar or almonds for hours with the grill lid cracked and no heat source running at all. The longer switchback path is the entire trick — more physical distance for the ember front to travel means a longer burn from the same footprint of pellets, which is why A-MAZE-N’s own maze outlasts its own tube roughly 3-to-1.
4. LIZZQ Premium Tube, 12” (Set of 2) — Best for Big Grills and Long Cooks
LIZZQ Premium Pellet Smoker Tube, 12" (Set of 2)
- Same hexagonal 304-stainless tube as the single, sold as a matched pair.
- Run both simultaneously on a large-capacity grill, or stagger them to roughly double effective smoke time.
- Makes sense on grills with 800+ sq in of cook space, where one tube's smoke output can feel thin.
- Same ~5-hour-per-tube manufacturer claim as the single unit.
Two tubes solve a problem one tube can’t: on a large grill, smoke from a single 12” tube can dissipate before it reaches food at the far end of the grate. Running two — one at each end, or one lit a couple hours after the first — keeps smoke output more even across a full-size brisket-and-ribs cook, at a cost that’s rarely more than a few dollars over buying two singles separately.
Tube vs. maze — which one do you actually need
| Straight tube | Maze / tray | |
|---|---|---|
| Burn time | ~4-5 hours (manufacturer claims) | Up to 12 hours |
| Best use | Boosting smoke on a hot or medium cook | Cold smoking (cheese, nuts, salt) with no heat |
| Footprint | Long and narrow, easy to tuck to one side | Wider, needs a flatter open spot |
| Refill mid-cook | Simple — relight the far end | More fiddly to relight a maze mid-burn |
If you’re deciding between the two for a first purchase: buy a tube if your goal is “my pellet grill food doesn’t taste smoky enough,” which is almost always a symptom of cooking too hot rather than a real grill defect. Buy a maze instead if the goal is dedicated cold smoking, where the whole point is smoke without heat for hours at a time.
How to light and run one
Torch one end of a filled tube for 30-60 seconds until the pellets catch and hold a small flame, let it burn openly for about 5 minutes to establish a solid ember, then blow the flame out so it smolders and smokes rather than burns. Pack pellets snugly by tapping the tube, not by forcing them in — over-compressed pellets restrict airflow and can snuff out early. Keep the tube away from direct grease drip and standing moisture in the tray, both of which will kill a smolder faster than anything else. If it goes out partway through, that’s a packing or moisture issue, not a defect — empty, dry, and relight.
Use the same food-grade hardwood pellets you’d load into your grill’s hopper — hickory, oak, cherry, apple, mesquite, or a blend. Skip pellet-stove heating pellets, which use different binders and aren’t rated food-safe, and skip loose sawdust, which burns roughly twice as fast and far less predictably than a pressed pellet. Our best wood pellets for smoking guide covers which hardwoods to buy for the tube itself, not just the hopper.
Where a tube fits in your setup
A smoke tube is a five-to-thirty-dollar fix for pellet grilling’s one real flavor complaint, and it belongs on the same short list as the other genuinely useful add-ons in our best pellet grill accessories roundup. It’s also the standard answer whenever the question is “how do I get more smoke flavor without babysitting a fire,” which comes up constantly in the pellet grill vs. charcoal debate — a tube is how a pellet grill closes most of that flavor gap while keeping the hands-off convenience that makes it a pellet grill in the first place.
