AV-EPDM flange gaskets are low-torque, double-convex ring gaskets made from EPDM rubber, ideal for plastic pipe systems needing excellent sealing with minimal bolt pressure, offering great chemical resistance, ozone/UV stability for outdoor use, and compatibility with water, steam, and mild chemicals, often enhanced with PTFE or PVDF for more aggressive fluids. They provide a bubble-tight seal for thermoplastic valves and fittings, reducing installation effort compared to flat gaskets
