Construction & Design

The Cometic MLS Head Gasket features multiple embossed layers of stainless steel that provide exceptional strength and the ability to rebound under pressure, maintaining a tight seal. The outer layers are coated on both sides with Viton, a fluorocarbon elastomer known for its excellent heat resistance up to 250°C (482°F) and chemical durability. This coating enhances sealing performance against various surface finishes and protects the gasket in harsh engine environments.

The uncoated stainless steel center shim layer allows for precise thickness control, ensuring a perfect seal tailored to the specific requirements of the 5.7L VVT HEMI engine. This multi-layer design effectively manages the differential expansion rates between aluminum heads and blocks, preventing leaks and maintaining engine performance over time.
