Overview
This Stainless Steel Flanged D-Ring Gasket is a precision-engineered sealing solution designed for critical high-pressure and high-temperature flange connections. It is specifically constructed to provide a leak-tight seal in demanding industrial piping systems, chemical processing, and power generation applications. The gasket features a robust metal winding with a flexible graphite filler, creating a resilient seal that compensates for flange irregularities and thermal cycling. With a pressure rating of 580 PSI (PN40) and a nominal bore of 14.8 inches (DN350), it is built for reliability in the most challenging service environments.
Key Features
Engineered for high-pressure service up to 580 PSI (PN40) D-Ring design with inner and outer containment rings for superior sealing integrity Metal winding construction with flexible graphite filler for adaptability Excellent corrosion resistance from 304 and 316L stainless steel materials Conforms to GB/T4622.2-2003 specifications for guaranteed dimensional accuracy Prevents gasket blow-out under high pressure or vacuum conditions Suitable for a wide range of temperatures and media
