GRAFOIL-GHR Gaskets

Gasketwholesale is the #1 source for Grafoil GHR ring gaskets. Contact us for full face style or custom designs.

Grafoil ® GHR is composed of flexible graphite laminate adhesively bonded to both faces of a flat 316/316L stainless steel insert (0.002? thick) generated from material typically 98% graphite. GHR is suitable for standard industrial fluid sealing applications. Such as chemical, petrochemical, refinery, steam service, and cryogenic applications. While maintaining an effective seal, Grafoil® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced. GHR is non-fibrous, non-asbestos, and has an adhesive bond. GHR has no binders nor resins.
