Key Features:

Designed to meet the rigorous demands of modern high-performance engines, the Cometic MLS Cylinder Head Gasket incorporates advanced materials and construction techniques:

• Constructed from three to five layers of high-grade stainless steel for superior strength and durability
• Embossed outer layers to improve sealing under varying load conditions
• Coated on both sides with heat-resistant Viton rubber, rated up to 250°C (482°F), to resist corrosion and chemical attack
• Precision-engineered to fit a 4.125-inch bore, matching factory specifications for a perfect seal
• Designed to rebound and maintain sealing integrity under thermal cycling and high pressure
• Compatible with a variety of surface finishes and sealing environments
• Ideal for use in naturally aspirated and forced induction applications
• Manufactured to strict quality control standards for consistent performance

Construction & Design:

The Cometic MLS gasket features a robust multi-layer steel design, combining three to five layers of stainless steel to provide exceptional strength and flexibility. Stainless steel is chosen for its ability to withstand high temperatures, resist corrosion, and maintain its shape under extreme pressure. The gasket’s embossed outer layers enhance sealing by creating a controlled deformation that adapts to surface irregularities.

Both sides of the gasket are coated with a Viton rubber compound, known for its excellent heat resistance and chemical durability. This coating ensures a reliable seal even in harsh engine environments, preventing leaks of coolant, oil, and combustion gases. The gasket thickness of 0.140 inches is optimized for the Chrysler 6.1L Gen-3 Hemi engine, ensuring proper compression and combustion chamber sealing.
