This 1.5 inch spiral wound gasket is engineered for reliable sealing performance in demanding applications. Constructed to meet ASME B16.20 standards, it ensures compatibility and proper fit with standard 150# raised face (RF) flanges. The gasket's design combines the strength of 316 stainless steel windings with the excellent sealing properties of a flexible graphite filler.
The addition of a 316 stainless steel outer ring provides enhanced stability and blowout resistance, making it suitable for a wide range of process fluids and temperatures. The 0.175 inch thickness offers optimal compression and sealing capabilities.
