Overview
This spiral wound gasket is engineered for demanding industrial sealing applications in piping and pressure vessel systems. It is constructed to exacting SH/T3407-2013 standards, ensuring reliable performance in critical service. The gasket is designed for use on 2-inch nominal diameter flanges with a pressure class rating of 300 PSI. Its robust construction provides a secure, leak-free seal capable of withstanding thermal cycling, pressure fluctuations, and challenging chemical environments.
Key Features
Engineered with a 304 stainless steel winding for structural integrity and spring-back Filled with a polytetrafluoroethylene (PTFE) layer for broad chemical resistance
Includes integrated outer and inner containment rings for enhanced stability Rings control bolt load distribution and prevent gasket over-compression Suitable for both indoor and outdoor installation and long-term service
Provides a conformable seal on standard flange faces
