Yellow Band Spiral Wound Gasket With Gray Stripe For 8 Inch 400 Class Flange 304 Stainless Steel Windings And Flexible Graphite Filler That Stays Tough Under High Temperature And Thermal Cycling

Single Spiral Wound Gasket for 8-Inch Class 400 Flanges ✔️ 304SS windings with flexible graphite filler; -150°F to 842°F

This spacer-line gasket is a spiral wound design intended for ASME B16.20 gasket requirements on B16.5 Class 400 flanges. Built around a center ring, it locates precisely on the flange face, adds radial strength, and limits compression for reliable sealing in high-heat, high-pressure piping systems. Commonly used in power, petrochemical, and process industries where tough service and reusability under thermal cycling matter.

✅ 8" pipe size, 400# class flange, 304 stainless steel windings with graphite filler
✅ Centering ring for accurate placement and controlled compression
✅ Spiral winding combines metal and soft filler for strong, sealable joints
✅ Temperature range -150 to 842 F, suitable for extreme heat and cycling
