Construction & Design

The Cometic MLS head gasket features a multi-layer steel design composed of several embossed stainless steel layers that provide both strength and the ability to rebound under pressure. The outer layers are coated with Viton, a high-performance fluoroelastomer known for its exceptional resistance to heat, oil, and chemicals, ensuring a reliable seal in harsh engine environments.

The uncoated stainless steel center shim maintains the gasket’s thickness and structural integrity, accommodating the differing thermal expansion rates between aluminum cylinder heads and cast iron or aluminum engine blocks. This precise engineering results in a gasket that offers long-lasting performance and superior protection against leaks.
