Rain Collars

With nearly a century of experience, Oatey® has become a trusted name in creating high-quality flashing solutions for commercial and residential applications. Oatey Rain Collars are designed to add an extra layer of protection against water intrusion by acting as a secondary seal over existing flashings around plumbing vent pipes.

These collars prevent water damage by sliding over the flashing and providing a robust, water-tight barrier. Ideal for projects where additional sealing is required, Oatey Rain Collars are constructed from durable materials to withstand harsh weather conditions, ensuring long-lasting protection. Easy to install, they offer peace of mind to homeowners and professionals alike by reinforcing the primary seal, extending the life of the roof, and enhancing overall moisture control.

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.

Does the pipe have to be lubricated before the flashing is installed over the pipe?

No. You should however bevel (chamfer) the pipe end to prevent cutting or scaring of the rain collar as it is being pushed over the pipe.
