Construction & Design

The Cometic MLS Head Gasket features a robust multi-layer steel design composed of several embossed stainless steel layers. The outermost layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its exceptional heat resistance and sealing capabilities. This coating enables the gasket to maintain a tight seal under extreme thermal and mechanical stress.

The center shim layer is made from uncoated stainless steel, providing structural integrity and allowing for precise thickness adjustments to accommodate different engine builds. The embossed layers increase gasket elasticity, enabling it to rebound and maintain a consistent seal despite engine vibrations and thermal expansion.
