Overview
This spiral wound gasket is engineered for high-performance sealing in demanding industrial piping and vessel applications. It is constructed with a precision-wound core of 316 stainless steel, providing exceptional structural integrity and corrosion resistance. The winding is filled with a layer of PTFE (polytetrafluoroethylene), creating a resilient and chemically inert sealing surface. This combination delivers reliable containment for a wide spectrum of aggressive media, pressures, and temperatures, making it a versatile solution for critical flange connections.
