Thicker seals around the bore keeps pressurized gasses within the combustion chamber. Thicker bore seals usually results in weaker seals around the oil and water routes. However, TOMEI USA gaskets have been specially designed to distributed pressure evenly in order to maintain a high quality seal across the entire surface.

Engine specific gasket construction ensures optimal performance & least stress on block/head.

STAINLESS STEEL
Stainless steel is used across all our high performance gaskets. Robust and resistant to high temperatures,stainless steel facilitates efficient transfer of heat from the combustion chamber to the cylinder block. In addition, it’s flexible nature further strengthens the seal made by the spring-like beads which helps prevent issues such as blown gaskets and melted cylinder blocks.

UNIQUE RUBBER COATING
Both the top and bottom layers of the gaskets are coated in a specially developed unique rubber coating that reinforces the seal and contact with the head/block surfaces.
