Material Notes:
GRAFOIL® Grade GHJ is a laminate made with GRAFOIL® Grade GTC flexible graphite mechanically attached to a perforated, low-carbon steel core. Its applications include: exhaust manifold gaskets, exhaust sealing, gasoline/diesel head gaskets, EGR valve sealing, and turbo charger gaskets. It can be certified to meet Ford material spec ESEM8 G201-A. While maintaining an effective seal, GRAFOIL® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced. Laminate Construction: GRAFOIL® Grade GTC 0.0066" thick (prior to tanging) - Low-Carbon Steel Grade 1008 or 1010 (130 tangs per square inch) - GRAFOIL® Grade GTC
