Oatey 12403 Copper No-calk Roof Flashing 1.5 to 3 Inches

Product Description

The Oatey 12403 is a copper no-calk roof flashing designed to create a water-tight seal around plumbing vent pipe penetrations in both commercial and residential roofing applications. Plumbers and roofing contractors rely on this flashing to protect roof openings from water intrusion without the need for additional caulking or sealant. The self-sealing collar slides directly over the pipe and forms a secure, weatherproof connection on its own. This saves time on the job and reduces the chance of improper sealing caused by human error during caulk application. The patented All Flash design is a key advantage of the Oatey 12403. It allows a single unit to fit multiple pipe sizes ranging from 1.5 inches to 3 inches in diameter. This versatility means fewer SKUs to stock and fewer trips back to the supply house. The copper base construction provides long-term durability and resistance to corrosion, making it well suited for outdoor rooftop exposure over many years. The base measures 14.5 inches in length by 11 inches in width, providing broad coverage over the roof deck around the pipe penetration. The flashing is rated to handle temperatures up to 180 degrees Fahrenheit, which supports use in a wide range of climates and rooftop conditions. It meets applicable standards including NES 653, UPC, and IAPMO, giving inspectors and contractors confidence in code compliance. The 40-degree pitch design accommodates sloped roof surfaces common in residential construction. Each unit carries a 1-year manufacturer warranty. The Oatey 12403 ships 12 units per carton, making it practical for contractors who need to stock for multiple projects at once.
