Spiral Wound Gasket For 30 Inch Pipe With 304SS And Flexible Graphite Heavy Duty 900030A304GR300 ASME B16.20 B16.47 Class 300 31.25 In ID 37.50 In OD Centering Ring For Exact Alignment Heavy Duty High Temp And Pressure Cycling Teadit

Heavy-Duty Spiral Wound Gasket for 31.25 ID 37.50 OD
✔️ 304SS windings with flexible graphite filler; includes center ring

This single-unit gasket is designed for very large ASME B16.47 Series A flanges (Class 300) on 31.25 inch diameter piping. The center ring locates the gasket precisely on the flange face, adds radial strength, and limits compression to prevent over-tightening in high-temperature, high-cycle service. Color-coded yellow band with gray stripe helps quick identification in assemblies. Pack: 1 piece.

✅ 31.25 in ID and 37.50 in OD footprint for large-diameter flanges
✅ 304SS windings deliver corrosion resistance and long life
✅ Flexible graphite filler provides a tight seal across -150 to 842°F
✅ Centering ring enables precise alignment and compression control
