Overview
The Type 321 Stainless Steel and PTFE Spiral Wound Gasket is a precision-engineered sealing solution designed for high-performance flanged connections in industrial piping and pressure vessel systems. Its robust spiral wound construction creates a resilient, pressure-adaptive seal that compensates for flange irregularities and thermal cycling. This gasket is specifically configured for demanding service where both temperature resistance and broad chemical compatibility are critical.
Key Features
Engineered with a corrosion-resistant Type 321 stainless steel outer winding for structural integrity and temperature resilience. Features an inner filler of pure PTFE (polytetrafluoroethylene), offering exceptional chemical inertness and resistance to a vast range of corrosive media. The spiral wound design provides a spring-like action, maintaining seal integrity under variable pressures and temperatures. Suitable for both indoor and outdoor applications in challenging industrial environments. Manufactured to meet consistent industry dimensional and material standards for reliable interchangeability.
