Overview
This spiral wound gasket is engineered for high-pressure sealing in demanding industrial piping and flange applications. It features a robust construction with a 304 stainless steel outer and inner ring, wound continuously with a PTFE (polytetrafluoroethylene) filler. This combination delivers a reliable, leak-tight seal in systems operating up to 232 PSI (PN16) and offers superior resistance to a wide range of corrosive chemicals and media. The gasket is manufactured to conform with the GB/T4622.2-2003 standard, ensuring dimensional consistency and performance reliability for critical connections.
