Overview
The 304 Stainless Steel PTFE Spiral Wound Gasket is a precision sealing component designed for demanding industrial flange connections. Engineered to meet rigorous standards, this gasket provides a reliable, leak-tight seal in high-pressure and high-temperature piping systems. Its robust construction combines mechanical strength with superior chemical resistance, making it a critical solution for preventing fluid loss and ensuring system integrity in challenging process environments.
Key Features
Spiral wound construction for exceptional resilience and sealing force 304 stainless steel winding provides high tensile strength and temperature tolerance PTFE (Polytetrafluoroethylene) filler delivers outstanding chemical inertness and corrosion resistance Integrated inner and outer carbon steel retaining rings prevent gasket blow-out and buckling during installation
Designed for consistent performance in systems with high pressure and thermal cycling Pre-packaged for inventory efficiency and job site readiness
