Overview
This industrial-grade spiral wound gasket is manufactured to the HG standard for sealing critical flanged connections in process piping systems. It is engineered to create a reliable, leak-tight seal in applications involving high temperatures, variable pressures, and aggressive media. The construction combines the mechanical strength of a metal winding with the sealing resilience of a non-metallic filler, making it a versatile solution for a wide range of industrial services.
Key Features
Constructed with a winding of 321 stainless steel for excellent high-temperature performance and oxidation resistance Features a polytetrafluoroethylene (PTFE) filler offering superior chemical resistance across a broad pH range Designed to accommodate multiple pressure classes, providing flexibility for system design and maintenance
Suitable for both indoor and outdoor installation in controlled industrial environments
Precise dimensional compliance ensures proper fit and optimal sealing force distribution on flange faces
