Construction & Design:

The Cometic MLS head gasket is constructed from multiple embossed layers of high-grade stainless steel, providing exceptional strength and flexibility. The outer layers are coated on both sides with Viton, a fluorinated elastomer known for its outstanding resistance to heat, oil, and chemicals. This coating ensures a reliable seal even under extreme thermal and mechanical stress.

The gasket’s multi-layer steel design allows it to absorb and rebound from the differential expansion between aluminum cylinder heads and cast iron or aluminum engine blocks, preventing leaks caused by shearing forces. The center shim layer is uncoated stainless steel, which can be customized to meet specific thickness requirements, ensuring a perfect fit and optimal sealing surface.
