API 601 Spiral Wound Gasket 2 Inch 400 Class Flange With 304 Stainless Windings and Flexible Graphite Filler Yellow Band Gray Stripe Built Tough for High Temperature Thermal Cycling and Pressure Swings Centering Ring ASME B16.20 B16.5 Compatible
✔️ 2in (50.8 mm) gasket, 304SS windings, flexible graphite filler
This spiral wound gasket is designed for ASME B16.20 and B16.5 flange assemblies, especially Class 400 flanges. The centering ring accurately locates the gasket on the flange face, adds radial stiffness, and acts as a compression limiter. The winding combines metal with a soft filler to deliver a tight seal across a wide temperature range, making it ideal for high-temperature thermal cycling and pressure swings in piping systems. Yellow band with gray stripe aids quick orientation and proper seating in ASME flange connections.
