Construction & Design

The Cometic MLS gasket features a durable multi-layer stainless steel design that provides excellent strength and the ability to rebound after compression. This construction allows the gasket to conform to surface irregularities between the cylinder head and engine block, ensuring a tight, leak-free seal. Embossed outer layers increase sealing pressure around critical areas such as combustion chambers and coolant passages.

Both sides of the gasket are coated with Viton rubber, a high-performance elastomer known for its resistance to heat, chemicals, and oil. This coating enhances the gasket’s ability to maintain a reliable seal in harsh environments and under varying load conditions. The .089-inch thickness is optimized for the 5.7L Gen-3 Hemi engine, balancing durability with precise fitment.
