Construction & Design

The Cometic MLS Cylinder Head Gasket features a robust multi-layer steel design utilizing premium stainless steel layers that provide exceptional tensile strength and flexibility. This construction allows the gasket to maintain a tight, reliable seal even under extreme thermal cycling and mechanical stress common in high-performance engines.

The embossed outer layers are coated with a specialized Viton rubber compound, which enhances sealing by conforming to surface imperfections and resisting chemical degradation.
