Overview
This 316L stainless steel spiral wound gasket is a precision sealing component designed for high-pressure, high-temperature flange connections in critical industrial piping systems. Engineered to meet rigorous international standards, it provides a dependable metal-to-metal seal that prevents leakage in demanding service environments. The D-type design incorporates integral inner and outer containment rings, which control compression and prevent over-tightening damage to the seal faces. With a nominal diameter of 24.8 inches and a pressure rating of PN16, this gasket is built for reliability in major process applications.
