Overview
This industrial-grade spiral wound gasket is engineered for high-pressure sealing in critical flange connections. Designed to meet the rigorous HG/T 20631-2009 standard, it is built for reliability in demanding process environments. The gasket features a robust construction with a 304 stainless steel winding and a polytetrafluoroethylene (PTFE) filler, delivering superior performance against a broad spectrum of corrosive chemicals and media. The inclusion of 304 stainless steel inner and outer rings provides structural stability, prevents gasket blowout, and guards against over-compression during bolt-up, ensuring a consistent and lasting seal.
