Key Features:

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design elements to provide exceptional durability and sealing integrity:

• Constructed from multiple embossed layers of stainless steel for enhanced strength and flexibility
• Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F)
• Compressed operating thickness of 0.036 inches for precise sealing
• Designed to handle the shearing forces between aluminum heads and both aluminum and cast iron blocks
• Corrosion-resistant materials ensure long-lasting performance under harsh conditions
• Center shim layer of uncoated stainless steel allows for thickness customization
• Specifically sized for a 4.125-inch bore with aluminum sleeved block compatibility

Construction & Design:

The Cometic MLS head gasket features a robust multi-layer steel construction that combines durability with flexibility. Each layer is precision-embossed to maintain a secure seal under extreme pressure and temperature fluctuations common in high-performance engines. The outer layers are coated with Viton, a premium fluorocarbon elastomer known for its exceptional heat resistance and chemical stability, ensuring the gasket maintains its integrity over time.

The center shim layer is made from uncoated stainless steel, providing the necessary rigidity and allowing for precise thickness adjustments to accommodate specific engine tolerances. This design effectively manages the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and gasket failure.
