Heavy Duty High Temperature Spiral Wound Gasket With Yellow Band And Gray Stripe For 18 Inch 400 Class Flanges 304SS Windings With Flexible Graphite Filler For Thermal Cycling And Pressure Variations Teadit 900018304GR400 Sur Seal

Heavy Duty 18in Spiral Wound Gasket with Graphite
✔️ 304SS windings with graphite filler; 18 in, class 400, single unit

Heavy Duty Spiral Wound Gasket designed for ASME B16.20 and B16.5 Class 400 flange connections. The centering ring accurately locates the gasket on the flange face, adds radial strength, and acts as a compression limiter for consistent sealing. This design uses spiral windings of 304 stainless steel with a flexible graphite filler to deliver a robust seal through thermal cycling and pressure variations. Identified by a yellow band with a gray stripe for quick visual verification, it is built for tough high-temperature service from -150 to 842 °F on 18" piping.
