Construction & Design:

The Cometic MLS Cylinder Head Gasket features multiple embossed layers of stainless steel, providing exceptional strength and flexibility. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its excellent heat resistance and sealing capabilities in harsh environments. This coating ensures a tight seal against combustion gases, coolant, and oil, preventing leaks and maintaining engine integrity.

The gasket’s center layer is an uncoated stainless steel shim, allowing for precise thickness adjustments to match specific engine requirements. This multi-layer design enables the gasket to absorb and compensate for the differential expansion between aluminum heads and cast iron or aluminum blocks, reducing the risk of gasket failure under extreme operating conditions.
