PTFE Ring Gasket W/304 SS Core

Made from virgin PTFE resin totally encapsulating a perforated 304 stainless steel reinforcement ring, a molded PTFE / 304SS insert gasket is resistant to creep and cold flow, it has exceptional sealability qualities. Ring gaskets are a flat sealing element, consisting of an inner and outer diameter sized to fit a flange's bore and bolt circle. Ring gaskets sit inside the flange's bolt circle. ASME B16.20 govern the dimensions of ring gaskets for standard diameter pipe flanges.
