Overview
This D-shaped spiral wound gasket is engineered for high-pressure sealing in demanding industrial applications. It features a robust construction of 304 stainless steel for the winding and a carbon steel inner and outer ring, providing excellent resilience and crush resistance. With a bore diameter of 8.74 inches and a thickness of 0.177 inches, it is rated for PN100/160 pressure classes. The design ensures a reliable metal-to-metal seal for flanged connections, effectively preventing leaks in systems handling steam, oil, or gas. Each order includes two gaskets for convenient inventory or project use.
