OATEY 12865 – Frequently Asked Questions

1) What pipe size does the Oatey 12865 roof flashing fit?
The Oatey 12865 is sized for 4 inch vent pipe. The self-sealing collar slides down over the pipe and seals without caulking, so there is no sealant step at the stack.
2) Can I use this Oatey aluminum vent flashing on a flat or low-slope roof?
It covers pitch from 0 to 40 degrees, so a flat or low-slope deck is within range. The limit is the roof construction, not the slope: it is not for hot-mopped or built-up roofs, so on a BUR assembly you need a different flashing.
3) Is the Oatey 12865 flashing rated for a Type B gas vent?
Yes. It is approved for Type B installations and rated for 180 degrees F continuous heat, so it works on a B-vent penetration as well as a plumbing stack.
4) How big is the base on the Oatey 12865, and will it lay in under shingles?
The stamped soft aluminum base measures 18 in. x 18 in. The aluminum is soft enough to shape to the deck and course of the roof, which is what lets it tuck under the shingles above the penetration.
5) Can I paint the collar or seal the Oatey 12865 with roofing tar?
No. Keep petroleum based products and paint off the flashing collar and plastic base, since they degrade the seal material. The collar is designed to seal on its own against the pipe.
6) Will an aluminum roof flashing rust out on a coastal or high-rain job?
The stamped soft aluminum base is rustproof, so it will not corrode through the way a plain steel base can. Note the aluminum is soft by design, which helps forming but means it dents if you walk on it hard during install.
7) What part number do I order for the Oatey 4 inch aluminum roof flashing with an 18x18 base?
Order Oatey model 12865. That is the 4 in. soft aluminum flashing with the 18 in. x 18 in. base and self-sealing collar.
