Overview
This ASME B16.20-2007 compliant spiral wound gasket is engineered for sealing flanged connections in demanding industrial piping systems. Designed for 1-inch nominal pipe size (NPS) at a 150-pound pressure class, it provides a reliable, leak-tight seal in critical applications. The gasket combines a resilient metal winding with a non-metallic filler, all contained within a sturdy outer ring, to ensure optimal performance under compression, thermal cycling, and variable pressure conditions. It is suitable for both indoor and outdoor use in a wide range of service environments.
Key Features
ASME B16.20-2007 standard compliance for guaranteed dimensional interchangeability Construction with a 316L stainless steel winding for corrosion resistance PTFE (polytetrafluoroethylene) filler for broad chemical compatibility and low friction Integral 316L stainless steel outer ring for radial stability and protection against over-compression Designed for flanged joints in piping systems, valves, and pumps
Effective sealing across a range of temperatures and pressures
