ASME B16.20-2007 DN80 900LB 316L Spiral Wound Gasket, 3" NPS, Pkg Qty 6
Overview
This precision-engineered spiral wound gasket is manufactured to the rigorous ASME B16.20-2007 standard for critical sealing applications. Designed for nominal 3-inch piping systems rated for 900-pound class service, it provides a robust, leak-proof seal in high-pressure and high-temperature environments. The gasket's construction combines the strength of metal with the sealing compliance of a non-metallic filler, creating a reliable barrier for demanding process fluids in industrial piping, valves, and flanges.
Key Features
Compliant with ASME B16.20-2007 standard for dimensional and material consistency Engineered for 900LB class high-pressure service conditions Dual-ring design with inner and outer guide rings for centering and compression control Outer guide ring constructed from 316L stainless steel for corrosion resistance Sealing winding core combines 316L stainless steel with PTFE (polytetrafluoroethylene) filler Inner guide ring made from 316L stainless steel for added structural stability PTFE filler provides excellent chemical resistance to a wide range of media Suitable for both indoor and outdoor installation environments
