ASME B16.20 Metal Spiral Wound Gasket, 12" 150LB, 304SS/PTFE, Pkg Qty 2
Overview
Engineered for critical sealing applications in demanding industrial environments, this spiral wound gasket is manufactured to the exacting requirements of ASME B16.20-2007. Designed for nominal pipe size (NPS) 12-inch flanges with a 150LB pressure class rating, it delivers a reliable, leak-tight seal in high-pressure and high-temperature piping systems. The robust construction combines the strength of metal with the sealing properties of a non-metallic filler, making it an essential component for maintenance, repair, and new assembly operations where system integrity is paramount.
Key Features
ASME B16.20-2007 compliant design for guaranteed dimensional accuracy and performance. Constructed with 304 stainless steel windings for excellent corrosion resistance and mechanical strength. PTFE (polytetrafluoroethylene) filler provides superior chemical resistance against a wide range of aggressive media. Integral inner ring, constructed from 304 stainless steel, provides radial stability and prevents gasket blow-out under pressure cycling. Specifically rated for 150LB flange service, ensuring suitability for a broad range of industrial pressure applications. Supplied as a pair, offering immediate availability for both sides of a connection or for stocking spare inventory.
