Cometic Subaru EJ25 100mm Bore .056 inch MLS Head Gasket

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed layers of stainless steel, featuring an outer layer coated with Viton rubber. This construction is key for sealing high-output engines, and it means you don't need to use additional sealants. MLS gaskets are well-suited for joining aluminum heads to either aluminum or cast iron blocks, as they can handle the stress that arises from dissimilar metals working together.

The strength of these gaskets comes from their layered stainless steel design, which also allows them to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton, a heat-resistant material capable of withstanding temperatures up to 482°F (250°C). Viton is chosen for its ability to perform in tough sealing conditions, under various loads, and on different surface finishes. The center layer is uncoated stainless steel, and its thickness can be adjusted to meet different requirements, like the 0.056 inch compressed operating thickness of this particular gasket, which has a 100mm bore.

This gasket fits a range of vehicles, including models like the Jaguar XK series, Subaru Forester, Impreza, and Legacy. It's a solid option when you need reliable sealing for your engine rebuild.
