Construction & Design

The Cometic MLS Cylinder Head Gasket is meticulously crafted from high-grade stainless steel layers that provide exceptional strength and resilience under demanding conditions. The gasket’s outer layers are embossed and coated with Viton, a premium fluorocarbon elastomer known for its outstanding heat resistance and chemical durability. This ensures a reliable seal even under harsh thermal and mechanical stresses commonly encountered in high-output engines.

At its core, the gasket features a stainless steel shim layer that can be customized to precise thickness specifications, accommodating various engine builds and tolerances. This multi-layer design allows the gasket to maintain a tight seal despite differential expansion between aluminum heads and cast iron or aluminum blocks, effectively preventing head gasket failure and enhancing engine longevity.
