Overview
This ASME B16.20-2007 compliant metal wound gasket is engineered for high-pressure sealing in piping systems. Designed for NPS 1-1/4" flanges with a 300LB pressure rating, it provides a robust and reliable seal in demanding industrial environments. The spiral-wound construction combines the strength of metal with the resilience of a specialized filler, ensuring long-term leak prevention against a wide range of media, pressures, and temperatures. It is suitable for both indoor and outdoor applications.
