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 rebound and maintain a tight seal even under extreme thermal cycling and mechanical stress. The embossed outer layers are coated with a specialized Viton rubber compound, which enhances sealing performance by conforming to surface imperfections and resisting chemical degradation.

Viton’s high heat tolerance up to 250°C (482°F) ensures the gasket remains effective in the demanding environment of the 5.7L Gen-3 Hemi engine. This combination of materials and engineering results in a gasket that offers superior durability, corrosion resistance, and leak prevention compared to conventional gaskets.
