Construction & Design:

The Cometic MLS gasket features a robust construction using multiple layers of stainless steel, which provides excellent strength and the ability to rebound after compression. This multi-layer design allows the gasket to conform to surface irregularities, ensuring a tight seal between the cylinder head and engine block. The 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 leak-free seal in harsh environments and under varying load conditions. The gasket thickness of .089 inches is optimized for the 5.7L Gen-3 Hemi engine, balancing durability with precise fitment.
