Oatey 12404 No-calk Roof Flashing Copper Base 3 to 4 Inches Pipe

Product Description

The Oatey 12404 No-Calk Roof Flashing is a copper base flashing designed to create a watertight seal around plumbing vent pipes where they penetrate through a roof. This flashing fits pipes ranging from 3 to 4 inches in diameter, making it a versatile choice for both residential and commercial plumbing projects. Plumbers, roofers, and general contractors rely on this type of flashing to prevent water intrusion at roof penetration points, one of the most common sources of leaks in any structure. The self-sealing collar slides directly over the pipe without the need for caulk or additional sealants, which speeds up installation and reduces the chance of improper application. The copper base resists corrosion and holds up well against UV exposure, temperature swings, and moisture over the long term. This flashing carries a pitch rating of 40 degrees, making it suitable for standard sloped roofs commonly found in residential construction. The overall base measures 15.5 inches in length by 12 inches in width, providing solid coverage around the pipe penetration area. It meets NES 653, UPC, and IAPMO standards, so it is accepted on jobs requiring code-compliant materials. The temperature rating reaches up to 180 degrees Fahrenheit, allowing it to handle the heat exposure typical of sun-facing roof surfaces. Each unit weighs approximately 1.667 pounds and is available in a carton quantity of 12, which works well for contractors stocking up for multiple jobs. Whether you are roughing in a new build or replacing worn flashing on an existing structure, the Oatey 12404 delivers reliable performance with minimal installation effort.
