Construction & Design:

The Cometic MLS Cylinder Head Gasket features a multi-layer steel construction that combines strength and flexibility. The stainless steel layers provide exceptional tensile strength and the ability to rebound after compression, which is critical for maintaining a consistent seal as the engine heats and cools. The embossed outer layers increase the gasket’s ability to conform to the cylinder head and block surfaces, enhancing sealing performance.

Both sides of the gasket are coated with Viton rubber, a synthetic fluoropolymer elastomer known for its excellent chemical resistance and high-temperature tolerance. This coating ensures a tight seal even in harsh operating environments, resisting degradation from engine fluids and thermal cycling. The .120-inch thickness is optimized for the 5.7L Gen-3 Hemi, balancing durability with precise fitment.
