Material Notes:
GRAFOIL® SUPER GTO® flexible graphite sheet is a gasketing material containing no binders, which will seal a wide variety of liquids and gases over an extremely large temperature range (-240°C to 525°C). SUPER GTO® is specifically designed to resist oxidation and corrosion in high-temperature environments. Primary applications are in exhaust systems where oxidation resistance is critically important. While maintaining an effective seal, GRAFOIL® material exhibits virtually no creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced.
