DWV Flanges

Flanges are fittings that are designed to connect pipes to other accessories or items. In the case of DWV flanges, they are most commonly used to connect toilets to the sewer pipe. Flanges look light small discs and are connected together using bolts, clamps or compressive force, with bolts being the most common. DWV flanges are specifically designed for use in drain, waste and vent applications in both commercial and residential settings. All of our DWV flanges meet ASTM D1784 Standards and are also NSF-14 Certified.
