Overview
This spiral wound gasket is engineered for high-pressure, high-integrity sealing in critical flange connections. It is constructed with alternating layers of 316L stainless steel windings and a PTFE (polytetrafluoroethylene) filler, creating a resilient seal that conforms to flange face imperfections. The design incorporates integral inner and outer retaining rings, which provide structural stability to prevent gasket blow-out or buckling under extreme compression and pressure cycling. It is suitable for systems operating at pressures up to approximately 363 PSI.
Key Features
Robust construction with 316L stainless steel windings for strength and corrosion resistance PTFE filler layer provides superior chemical resistance to a wide range of aggressive media Integral inner and outer retaining rings for enhanced stability and installation control Engineered to seal effectively on standard raised face flanges Designed for high-pressure applications and temperature cycling environments
