Construction & Design

The Cometic MLS Head Gasket is constructed from multiple embossed layers of high-grade stainless steel, delivering exceptional strength, flexibility, and longevity. The outer layers are coated on both sides with Viton, a premium 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 multi-layer steel design allows the gasket 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, precisely tailored to meet thickness requirements, ensuring a perfect fit and optimal sealing surface for your engine rebuild or upgrade.
