Key Features:

Cometic’s MLS Cylinder Head Gasket incorporates cutting-edge technology and materials to meet the rigorous demands of modern engines:

• Multi-layer stainless steel construction for enhanced strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
• Compressed operating thickness of 0.098" for precise fitment and sealing
• Designed to withstand shearing forces between aluminum heads and cast iron or aluminum blocks

Construction & Design:

The gasket is constructed from multiple embossed layers of stainless steel, providing a robust and flexible seal capable of rebounding under pressure and resisting corrosion. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its exceptional heat resistance and durability in harsh sealing environments. This design ensures a tight, reliable seal that accommodates the thermal expansion differences between aluminum cylinder heads and various block materials.

The uncoated stainless steel center shim layer adds structural integrity and can be tailored to meet specific thickness requirements, ensuring optimal compression and sealing across the combustion chamber.
