Spiral Wound Gasket With Flexible Graphite Core For High Temperature Variations And Thermal Cycling 38 Inch Size 38.25 ID 42.25 OD 304SS And Flexible Graphite Filler ASME B16.20 B16.47 Series A Flanges Class 400 Teadit 900038A304GR400

High-Temp Spiral Wound Gasket with Graphite Core - 38 in
✔️ 38 in nominal size, single gasket, 38.25 ID/42.25 OD, 304SS windings

This spiral wound gasket is designed for high-temperature sealing on ASME B16.20/gasket standards for ASME B16.47 Series A Flanges Class 400. The centering ring locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter. The sealing element combines spiral windings with a flexible graphite filler to handle thermal cycling and broad temperature swings.
