Overview
This D-type spiral wound gasket with inner and outer rings is a precision sealing component designed for demanding industrial flanged connections. It is engineered to provide a reliable, leak-tight seal in high-pressure and high-temperature piping systems. Manufactured to conform with recognized industry standards, this gasket is suitable for critical service applications where sealing integrity is paramount. The combination of durable metal windings and a resilient filler material ensures long-term performance under cyclic loading and harsh chemical exposure.
Key Features
Constructed with 304 stainless steel windings for strength and corrosion resistance Features a polytetrafluoroethylene (PTFE) filler for excellent chemical inertness and sealing Includes integral inner and outer containment rings to prevent gasket blow-out under pressure Designed for a nominal pipe size of DN80, approximately 3 inches Rated for high-pressure service with a 900LB pressure class
Conforms to industry specifications for dimensional consistency and material performance
