Overview
This 20-inch NPS metal spiral wound gasket is engineered for high-pressure sealing applications in demanding industrial piping systems. It is constructed to provide a reliable, leak-tight seal in flanged connections operating at pressures up to 150 PSI (PN20). The gasket's robust design combines the structural strength of metal with the sealing performance of a chemically resistant filler, making it suitable for a wide range of service conditions in both indoor and outdoor environments.
Key Features
