Overview
This ASME B16.20-2007 compliant spiral wound gasket is engineered for high-pressure sealing in industrial piping applications. Designed for 1/2" NPS, 300LB rated flanged connections, it provides a robust and reliable seal capable of withstanding demanding thermal cycling, pressure fluctuations, and exposure to a wide range of chemicals. The precision-wound construction ensures consistent performance and long-term leak prevention in critical service lines.
Key Features
ASME B16.20-2007 standard compliance for guaranteed dimensional accuracy and performance
Spiral wound design with resilient graphite filler for superior sealing under variable pressures and temperatures 304 stainless steel inner winding provides structural integrity and corrosion resistance 304 stainless steel outer ring (centering ring) for proper gasket alignment and to prevent over-compression during bolt-up
Excellent thermal stability and chemical resistance suitable for a broad spectrum of industrial media Engineered for reliable, long-term service in high-pressure piping systems
