Spiral Wound Gasket For High Temperature Variations And Thermal Cycling 52 Inch Pipe Size With 400 Class ASME B16.20 Compliance 53 Inch ID 57.25 Inch OD 304 Stainless Steel Core And Flexible Graphite Sealing Heavy Duty Teadit 900052A304GR400

High-Temp Spiral Wound Gasket for 26 in Pipe, Class 400
✔️ 304SS windings with graphite filler, 53 in ID, 57.25 in OD

This single gasket is designed for high-temperature piping and is typically used on ASME B16.20 / B16.47 Series A Class 400 flange connections. The centering ring locates the gasket precisely on the flange face, adds radial strength, and acts as a compression limiter for consistent seal performance. The winding combines a robust 304 stainless steel core with a flexible graphite sealing filler to deliver reliable sealing across thermal cycles and wide temperature swings.
