Overview
This 12-inch spiral wound gasket is engineered for high-integrity sealing in demanding industrial piping systems. Manufactured in strict compliance with the SH/T standard, it is specifically designed for use on steel pipe flanges rated for 900LB pressure classes. The gasket's construction utilizes a PTFE (polytetrafluoroethylene) chemical base, providing exceptional resistance to a wide spectrum of corrosive media. The inclusion of 304 stainless steel inner and outer rings ensures dimensional stability and prevents over-compression during flange bolt-up, making it a reliable, long-term sealing solution for critical service applications.
