J.I.S. Japan Engine offers our own line of gasket sets and individual gaskets. Our gaskets are manufactured with the highest quality materials from the U.S., Japan, and Germany. All gaskets either meet or exceed O.E. specifications. Most of our head gaskets are of a perforated steel core with a graphite facing, but some are steel, or multi-layered steel, in accordance with the O.E. design. Graphite is our material of choice, being that it’s heat resistant properties are excellent, it has perpetual flexibility and resilience, which aids in the sealing of imperfect surfaces, and does not stick. Most of our rear main seals and valve stem seals are made of viton. Viton being the material of choice, because of its resistance to solvents such as gasoline, motor oil detergents, and because of its resistance to extreme heat. (up to 400 degrees Fahrenheit) No one appreciates having to pull an engine because of a rear main seal failure. If you have any further inquiries, please feel free to contact us for more information.
