Overview
This D-Ring Style Metal Wound Gasket is a precision sealing component designed for high-integrity flanged connections in demanding industrial piping systems. It is engineered to provide a reliable, leak-tight seal under significant pressure and temperature fluctuations, making it a critical part of maintenance and assembly operations. The construction combines the strength of metal with the sealing properties of a non-metallic filler, creating a resilient gasket suitable for a wide range of service conditions.
Key Features
D-Ring design with inner and outer stainless steel containment rings Constructed with a 304 stainless steel winding core and outer rings
Features a polytetrafluoroethylene filler layer for enhanced sealing Rated for pressure classes up to PN25 (approximately 363 PSI) Manufactured to industry-standard dimensions for reliable fit and performance
Provides excellent resistance to creep relaxation under bolt load
