Overview
This 12-inch spiral wound gasket is engineered for demanding industrial sealing applications where reliability under pressure and chemical exposure is critical. It is constructed with a precision-wound 316 stainless steel metal winding, providing exceptional structural resilience and corrosion resistance. The winding is combined with a PTFE (polytetrafluoroethylene) fluoropolymer filler, creating a robust, multi-layered seal designed to perform consistently across a wide range of temperatures and pressures. Manufactured to recognized industry standards, this gasket is a fundamental component for creating leak-tight seals in flanged pipe connections and vessel assemblies.
