Oatey Company 11871 Galvanized Roof Flashing 1.5-3 in

Product Description

The OATEY COMPANY 11871 is a no-caulk, galvanized base roof flashing designed to seal pipe penetrations through roofing assemblies. Known as the All Flash style, it accommodates pipe sizes from 1.5 inches through 3 inches, making it a versatile single-SKU solution for a range of common pipe diameters. The galvanized steel base provides corrosion resistance in outdoor exposure, and the no-caulk design speeds up installation by eliminating the need for sealant application at the base. Plumbers and roofing contractors install this type of flashing during new construction and re-roofing projects to maintain a watertight seal around vent stacks and other pipe penetrations.

This flashing is suited for residential and light commercial roofing applications where plumbing vent pipes pass through the roof deck. Typical use cases include drain-waste-vent stack terminations on sloped roofs. It fits 1.5 inch, 2 inch, and 3 inch pipe, covering the most common residential vent pipe sizes in a single unit. The no-caulk design is particularly useful in production plumbing environments where installation speed is a priority.
