Construction & Design

The Cometic MLS head gasket features multiple embossed layers of high-grade stainless steel, providing a balance of strength and flexibility to maintain a reliable seal under extreme conditions. The outermost layers are coated on both sides with Viton, a fluorocarbon elastomer known for its exceptional resistance to heat (up to 250°C / 482°F) and chemical exposure. This coating enhances the gasket’s ability to seal against harsh environments and varying surface finishes.

The center shim layer is made of uncoated stainless steel, allowing for precise thickness control and effective management of thermal expansion differences between aluminum heads and aluminum or cast iron blocks. This multi-layer design minimizes the risk of leaks and gasket failure, even under rigorous thermal cycling and mechanical stress.
