OATEY 11549 – Frequently Asked Questions

1) What pipe size does the Oatey 11549 service mast flashing fit?
The Oatey 11549 is sized for 1-1/2 inch pipe. The galvanized flashing collar slides over the mast pipe and self-seals, so it is the right part only if your service mast conduit is 1-1/2 inch. A different conduit diameter needs a differently sized flashing.
2) Do I need to caulk around the collar on the Oatey 11549 electrical service mast flashing?
No caulking is required at the collar. The collar is self-sealing and seals as it slides down over the pipe. What you do need to avoid is petroleum based products or paint on the flashing collar or the plastic base, which will degrade the seal.
3) Can I use this Oatey service mast flashing on a flat hot-mopped or built-up roof?
No. The 11549 is not for hot-mopped or built-up roofs. It is intended for roofs where a 12.5 x 8.75 inch galvanized base can be shingled or lapped in. For a tar or built-up assembly you need a flashing rated for that roof type.
4) Why does the collar come separate from the base on the Oatey 11549?
On this part the collar ships unattached from the flashing base specifically for electrical service mast work. That lets you set the base into the roofing course first, then drop the collar down over the mast pipe from above and seat it. Standard plumbing vent flashings come as one piece; this one is deliberately two.
5) What is the Oatey part number for a 1-1/2 inch galvanized electrical service mast flashing?
Oatey 11549. That is the manufacturer part number to order or cross reference, and it covers the 1-1/2 inch galvanized service mast flashing with the unattached self-sealing collar.
6) Is the Oatey 11549 an all-metal flashing or does it have a plastic part?
It's a mix. The base is 28 gauge galvanized steel and the flashing is galvanized, but there is a plastic component at the base that the warnings call out, which is why paint and petroleum based products have to stay off both the collar and the plastic base.
