Overview
The D-Ring Style Metal Wound Gasket is engineered for critical sealing applications in high-pressure, high-temperature piping systems. This composite gasket combines the mechanical strength of a 304 stainless steel spiral wound core with the superior sealing properties of an integrated PTFE (polytetrafluoroethylene) inner layer. It is manufactured to meet rigorous industry standards for flange connections, specifically designed for service up to 900 lbs pressure classes. The design provides a resilient, leak-tight seal that accommodates flange rotation and surface irregularities, making it a reliable solution for preventing fluid or gas loss in demanding industrial environments.
Key Features
Spiral wound construction with a 304 stainless steel outer wind and PTFE filler D-ring shape with integrated inner and outer retaining rings for precise placement and added stability Engineered for high-pressure applications rated up to 900 lbs Excellent corrosion resistance provided by 304 stainless steel PTFE layer offers broad chemical compatibility and a low-friction sealing surface Suitable for a wide range of temperatures due to the properties of stainless steel and PTFE Resists creep and relaxation under bolt load for a maintained seal
