Ideal for enthusiasts and professional builders seeking durability and precision, this gasket eliminates the need for additional sealants and withstands the rigors of performance driving and daily use.

Built to meet the exacting standards of modern high-performance engines, this gasket supports optimal combustion chamber sealing, helping maintain engine efficiency and longevity under extreme conditions.

Key Features:

Designed with advanced materials and construction techniques, the Cometic MLS Head Gasket offers:

• Multi-layer steel construction for enhanced strength and durability
• Embossed outer layers coated with Viton rubber for superior heat and chemical resistance
• Compressed operating thickness of 0.036" for precise sealing

Construction & Design:

The gasket is constructed from multiple embossed layers of stainless steel, providing exceptional strength and flexibility. The outer layers are coated on both sides with Viton, a high-performance fluorocarbon elastomer known for its outstanding heat resistance and durability in harsh sealing environments. This coating ensures the gasket maintains a reliable seal under extreme thermal and mechanical stress.

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 leaks and gasket failure.
