Construction & Design:

The Cometic MLS gasket features multiple embossed layers of stainless steel, providing exceptional strength and the ability to rebound under pressure. The outer layers are coated on both sides with Viton, a fluorocarbon elastomer known for its excellent heat resistance and chemical durability. This coating ensures a tight seal against combustion gases and coolant leaks while resisting degradation over time.

The center shim layer is made of uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design effectively manages the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing gasket failure due to shearing forces.
