Flashings

Oatey® invented the flashing more than 100 years ago. Today, Oatey flashings are used in commercial and residential applications where a water-tight seal around plumbing vent pipe or outside wall penetration is required. Flashings are available in a variety of thermoplastic, aluminum, galvanized and copper materials. All Oatey Flashings are rated for a minimum of 180°F continuous heat and approved for Type B Installations. Oatey also offers the Master Flash® for commercial applications, along with a variety of specialty items including Rain Collars and Mushroom Caps.

Frequently Asked Questions

How is a rain collar installed?

After the correctly sized collar has been selected; you will apply a 100% exterior or marine rated silicone caulk to the top of the existing rain collar attached to the roof flashing, and also to the underside of the new rain collar. Slide the new rain collar down over the pipe to the top of the existing collar. Press the new collar down with enough pressure to seal the two together without collapsing the seal around the pipe.

What are the maximum temperature rating for roof flashings?

Oatey Master Flash and Retro-Master Flash are rated for continuous temperatures up to 212°F. All other Oatey flashings are rated for B venting, which are continuous temperatures up to 180°F.

Can standard No-Caulk roof flashings be installed on a metal roof?

No. The Oatey Master Flash or Retro-Master Flash should be used in this application.
