Overview
This metal spiral wound gasket is engineered for high-integrity sealing in critical industrial piping and pressure vessel systems. Designed to meet the rigorous SH/T3407-2013 standard, it is built for 1/2 inch nominal pipe size (DN15) flanges rated for 600 PSI service. The gasket's construction combines mechanical strength with superior sealing performance, making it a reliable component for preventing leaks in challenging environments. Its inclusion of an inner ring provides added stability and prevents winding collapse during installation.
Key Features
