Oatey Company 12949 Aluminum Roof Flashing 3 in

Product Description

The OATEY COMPANY 12949 is a 3-inch aluminum roof flashing designed to create a weathertight seal where a vent pipe penetrates a sloped roof. Constructed from .032 aluminum, this flashing slides directly over the pipe and uses a non-fading, rustproof sealing collar to prevent moisture intrusion. The 18 x 18 inch base provides a broad contact area against the roof deck. Rated for continuous heat exposure up to 180 degrees F, this flashing is approved for Type B vent installations. HVAC technicians and plumbers install this component during new construction or re-roofing service calls.

This flashing is designed for use on pitched roofs where Type B vent pipes exit through the roof surface. The 40-degree pitch accommodation makes it suitable for a wide range of common residential roof slopes. It is appropriate for gas appliance venting applications that require a durable, code-compliant roof penetration seal. This product is not approved for hot-mopped or built-up roofing systems and should not be installed on flat or low-slope roofs requiring those methods.
