Spiral Wound Gaskets to ASME B16.20, Style CG, with 304/Graphite

Spiral wound gaskets Style CG with Graphite filler (98% pure) in their sealing element, and a solid 304 Stainless steel outer guide ring. The guide ring accurately centers the gasket on the flange face, provides additional radial support to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face ASME B16.5 flanges. Suitable configuration for temperature resistant applications in flue gas scrubber systems, cooling towers, incinerators, geothermal wells, biofuels. Ideal configuration for cryogenic applications.

A narrow strip of V-shape metal tape is spirally wound under tension with a filler cushion between the metal layers and spot-welded at both ends.

Spiral Wound Gaskets to ASME B16.20, Style CG, with 304/PTFE

Spiral wound gaskets Style CG with PTFE ( Teflon® ) in their sealing element, and a solid 304 Stainless steel outer guide ring. The guide ring accurately centers the gasket on the flange face, provides additional radial support to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face ASME B16.5 flanges. Suitable configuration for temperature resistant applications in corrosion resistant applications such as cooling towers, acid handlers, food, dairy processing equipment.
