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.
Key Features
Dual-material construction with 316 stainless steel for strength and PTFE for chemical resistance Suitable for sealing against a broad range of acids, bases, and solvents Designed to conform to common industry dimensional and material standards Spiral wound design provides excellent resilience and recovery under bolt load Effective sealing performance across variable pressures and temperatures
