Construction & Design

The Cometic MLS Head Gasket is crafted from premium stainless steel layers that provide exceptional strength, flexibility, and resilience. Its multi-layer design allows the gasket to maintain a tight seal despite thermal expansion and contraction cycles common in high-performance and heavy-duty engines.

The embossed outer layers are coated with Viton rubber, a synthetic fluoropolymer known for excellent heat resistance and chemical stability. This coating enhances the gasket’s ability to seal against combustion gases, coolant, and oil, preventing leaks and maintaining engine integrity over time.

Manufactured with precise thickness and bore dimensions, this gasket ensures proper engine compression and helps prevent cylinder head warpage. The combination of advanced materials and engineering makes it a reliable choice for both stock and modified 5.7L Gen-3 Hemi engines.
