Construction & Design

The Cometic MLS cylinder head gasket features a robust multi-layer steel design, combining three to five layers of high-grade stainless steel. This construction provides exceptional strength to resist the high cylinder pressures generated by the 5.7L Gen-3 Hemi engine. The embossed layers enhance the gasket’s ability to rebound, maintaining a consistent seal even under thermal cycling and mechanical stress.

Both sides of the gasket are coated with Viton rubber, known for its excellent chemical resistance and ability to maintain sealing integrity in harsh environments. This coating helps the gasket conform to surface irregularities and prevents leaks caused by oil, coolant, or combustion gases. The gasket’s heat tolerance up to 250°C (482°F) ensures reliable performance in high-temperature engine compartments.
