Heavy Duty Spiral Wound Gasket With Flexible Graphite For High Temperature Variations And Thermal Cycling, 34 Inch Pipe Size, Class 150, 304 Stainless Steel Core With Graphite Filler, ASME B16 20 And B16 47 A Flanges Teadit By Sur-Seal

Heavy Duty Spiral Wound Gasket for High-Temp Piping
✔️ 34 in pipe size, Class 150, 304 SS windings with graphite

The heavy-duty spiral wound gasket is designed for ASME B16.20 and B16.47 Series A flange connections in Class 150 service. It features a centering ring to accurately locate the gasket on the flange face, adding radial strength and acting as a compression limiter to prevent over-tightening. The windings are made from 304 stainless steel with a flexible graphite filler, delivering reliable sealing across wide temperature swings. Temperature range from -150 to 842 °F (-100 to 450 °C) makes it suitable for steam, petrochemical, and refinery piping under thermal cycling.
