How we scored them

Each pipe is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. Safety points go to stated listings and clearances: the Selkirk pipes are listed to UL-641 and UL-103; the DuraVent straight pipe states a 1 in clearance to combustibles. Warranty points go to the two with a stated limited lifetime warranty.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Buying guide: the best stove pipe for a pellet stove

The listing is the safety credential. The Selkirk 3VP-24 and 3VP-36 are listed to the UL-641 standard as well as the UL-103 standard, engineered for pellet and corn burning stoves. The DuraVent straight pipe states a 1 in clearance to combustibles. The DuraVent clean tee listing states no listing or clearance. A listed pipe is the baseline; an unlisted one is a gamble.

Double-wall construction is the pellet standard here. The DuraVent straight pipe is double-wall 18-gauge steel with a lock-seamed design. The Selkirk pipes have a 304 stainless steel inner wall and a paintable galvanized outer wall. Double-wall keeps the outer surface cooler and the exhaust hotter, which means better draft and less creosote. All three straight pipes here are 3 in diameter: match the stove’s outlet, not the chimney’s.

Length is a layout question. The DuraVent is 12 in; the Selkirk 3VP-24 is 24 in; the Selkirk 3VP-36 is 36 in. Longer sections mean fewer joints, and every joint is a potential leak. The DuraVent uses twist-lock construction with no sealant required; the Selkirk pipes use a coupling joint that connects in seconds. Fewer joints, tighter joints: that is the whole game.

The cleanout tee is the maintenance piece. The DuraVent 3PVL-TR is a 3 in pellet vent clean tee in galvanized steel, giving access to clear ash from the vent run. Pellet vents collect fly ash; without a cleanout, the ash collects until the draft suffers. The tee’s listing is thin: no listing, no clearance, no warranty term beyond the word “Warranty”. Buy it for the function, not the paperwork.

Warranty splits the set. The DuraVent straight pipe states a limited lifetime warranty; the Selkirk 3VP-36 states a manufacturers limited lifetime warranty. The Selkirk 3VP-24 states no warranty; the clean tee states only the word “Warranty” with no term. A stated lifetime term is the only promise you can hold.

The 304 stainless inner wall is the corrosion story. Pellet exhaust is acidic, and the Selkirk listings state a 304 stainless steel inner wall specifically. The DuraVent straight pipe states 18-gauge steel with a lock-seamed design. Stainless resists the acidic condensate better than plain steel; that is why the pellet-specific listings name it. The clean tee’s galvanized steel is the least corrosion-resistant of the set, which is one more reason it scores lowest.

Clearance to combustibles is the install figure that matters most. The DuraVent straight pipe states a 1 in clearance to combustibles. The Selkirk listings state no clearance figure. The stove manufacturer’s manual sets the required clearance for the whole vent run; the pipe’s stated clearance is the starting point, not the whole answer. When in doubt, the larger clearance wins.

The twist-lock versus coupling joint is a small but real difference. The DuraVent’s twist-lock needs no sealant per the listing; the Selkirk’s coupling joint connects in seconds per the listing. Both are tool-free in practice. What matters is that the joint stays tight through heat cycles: a joint that loosens leaks exhaust into the house. Check every joint at the start of each heating season.

Fly ash is the maintenance reality. Pellet stoves produce fine fly ash that settles in horizontal vent runs and elbows. The cleanout tee exists for exactly this: open the cap, clear the ash, close it up. Without a cleanout, the ash builds until the draft drops and the stove burns dirty. Plan a cleanout in every horizontal run; the DuraVent tee is the fitting for it.

The diameter question is settled here: all four are 3 in. Pellet stoves in this class vent through 3 in pipe; larger stoves or longer runs may need 4 in, but none of these listings is 4 in. Match the pipe to the stove’s outlet collar. An adapter to a different diameter is a draft compromise; avoid it where you can.

Around the Woodpile

• Diameter: all four are 3 in; match the stove outlet.
• Joints: twist-lock or coupling; no sealant per the DuraVent listing.
• Clearance: the DuraVent states 1 in to combustibles; check your stove manual for the rest.
• What to check on arrival: the listing marks, the joint fit, and the cleanout cap.

The gauge figure deserves a note. The DuraVent straight pipe states 18-gauge steel with a 1.3 mm nominal wall thickness. Heavier gauge resists denting during install and holds its shape through heat cycles; thinner pipe dents when you look at it wrong. The Selkirk listings state the same 1.3 mm nominal wall thickness. For a vent run that gets handled, bumped and heated, the stated gauge is a durability signal.

The paintable outer wall is the finish detail. The Selkirk pipes state a paintable galvanized outer wall: paint it to match the stove or the room. The DuraVent states a stainless steel color. An unpainted galvanized pipe in a living room looks like a shop part; a coat of high-temperature paint makes it disappear. Paint only the outer wall, never the inner.

Frequently Asked Questions

What pipe do I need for a pellet stove?

Type L pellet vent: double-wall, 3 in here, listed to UL-641. The Selkirk pipes state UL-641 and UL-103 listing; the DuraVent straight pipe states a 1 in clearance.

Can I use single-wall stove pipe?

None of these listings is single-wall; all are double-wall vent pipe. Follow the stove manufacturer’s venting requirements.

Do I need a cleanout tee?

The DuraVent 3PVL-TR is a 3 in cleanout tee for clearing fly ash from the vent run. Pellet vents collect ash; a cleanout makes the maintenance possible.

What lengths are available?

The DuraVent straight pipe is 12 in; the Selkirk 3VP-24 is 24 in; the Selkirk 3VP-36 is 36 in. Longer sections mean fewer joints.

The limited lifetime warranty needs a read of the fine print. Both the DuraVent and Selkirk listings state it, but neither listing quotes the terms: what is covered, for how long, and what voids it. A lifetime warranty on vent pipe typically covers manufacturing defects, not corrosion from neglect or damage from a chimney fire. Keep the receipt and the manual; the warranty is only as good as the paperwork.

Which pipes have a warranty?

The DuraVent straight pipe and the Selkirk 3VP-36 state a limited lifetime warranty. The others state no warranty term.

One last practical point: buy the whole run from one line. The DuraVent straight pipe and the DuraVent clean tee are the same PelletVent line with the same twist-lock logic; the two Selkirk pipes are the same VP line with the same coupling joint. Mixing lines means mixing joint systems, and adapters between them are another joint to leak. Pick a line and stay in it. The vent run is no place for improvisation or mixed parts ever. A clean, single-line vent with listed pipe, tight joints and a cleanout is the install that passes inspection and sleeps well.
