Overview:

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to deliver superior sealing performance for high-output engines, specifically designed for select Chrysler, Dodge, and Jeep models equipped with the 6.1L Gen-3 Hemi engine. This gasket ensures a reliable seal between the cylinder head and engine block, preventing leaks and maintaining optimal compression under demanding conditions. Ideal for enthusiasts and professionals seeking durability and precision, it requires no additional sealants and is compatible with both aluminum and cast iron engine components.

Built to withstand the stresses of modern performance engines, this gasket supports the integrity of your engine’s combustion chamber, helping to maintain power and efficiency while resisting corrosion and wear over time.

Key Features:

Designed with advanced materials and construction techniques, the Cometic MLS Cylinder Head Gasket offers the following key benefits:

• Multi-layer stainless steel construction for enhanced strength and durability
• Embossed outer layers coated with Viton rubber for superior sealing and heat resistance
• Compressed operating thickness of 0.098" for precise fit and sealing
• Compatible with aluminum heads to aluminum blocks and aluminum heads to cast iron blocks
• Resistant to shearing forces caused by differing metal expansion rates
• Corrosion-resistant materials extend gasket life and reliability
• Center shim layer of uncoated stainless steel customizable for thickness requirements
• Viton coating withstands temperatures up to 250°C (482°F) and harsh sealing environments
• No sealants required, simplifying installation and reducing potential failure points

Construction & Design:

The Cometic MLS Cylinder Head Gasket is meticulously crafted from multiple embossed layers of high-grade stainless steel. The outer layers feature a Viton rubber coating, a heat-resistant elastomer designed to maintain a tight seal under extreme thermal and mechanical stress. This coating is applied on both sides of the gasket, enhancing its ability to conform to surface imperfections and resist leaks.

The gasket’s center shim layer is made from uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design not only improves sealing performance but also provides the flexibility to absorb and rebound from the differential expansion of aluminum and cast iron engine components, preventing gasket failure due to shearing forces.
