Overview
This ASME B16.20 compliant metal wound gasket is engineered for high-pressure sealing in demanding industrial piping systems. Designed for a nominal pipe size of 3 inches with a 900LB pressure class, it provides a robust and reliable seal for critical flange connections. The construction utilizes a 316L stainless steel inner ring combined with a wound core of 316L stainless steel and a fluoropolymer filler, creating a resilient seal capable of withstanding extreme pressures, thermal cycling, and aggressive media. It is suitable for both indoor and outdoor installations.
Key Features
Manufactured to ASME B16.20-2007 standards for guaranteed dimensional accuracy and performance. Wound core construction of 316L stainless steel for structural integrity and resilience. Fluoropolymer filler material provides superior chemical resistance and low friction. 316L stainless steel inner ring (centering ring) ensures proper gasket alignment and prevents blow-out. Rated for high-pressure applications up to 2,220 PSI. Excellent thermal stability across a wide operating temperature range. Suitable for use in both indoor and outdoor environments.
