GRAFOIL® Grade GHH is a laminate made with GRAFOIL® Grade GTC flexible graphite chemically bonded to both faces of a flat, low-carbon steel core. Its applications include: exhaust sealing, gasoline/diesel head gaskets, EGR valve sealing, and turbo charger gaskets. While maintaining an effective seal, GRAFOIL® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced.
