Key Features

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design features to provide exceptional performance and longevity:

• Multi-layer steel construction for increased 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
• Compatible with aluminum-to-aluminum and aluminum-to-cast iron engine configurations
• Resistant to corrosion and able to withstand shearing forces between dissimilar metals
• No additional sealants required, simplifying installation and ensuring consistent performance
• Center shim layer of uncoated stainless steel customizable for thickness variations
• Heat resistance up to 250°C (482°F) thanks to Viton coating

Construction & Design

The Cometic MLS head gasket is meticulously engineered using multiple embossed layers of high-grade stainless steel. The outer layers feature a Viton rubber coating, a fluorocarbon elastomer known for its exceptional resistance to heat, oil, and chemicals. This coating enhances the gasket’s ability to maintain a tight seal under extreme operating conditions. The center shim layer is made of uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements.

This multi-layer design not only provides superior sealing but also offers the flexibility to absorb and rebound from the thermal expansion and contraction that occurs between aluminum heads and cast iron or aluminum blocks. This capability reduces the risk of gasket failure due to material fatigue or warping, making it an ideal choice for high-performance and heavy-duty applications.

Installation & Fitment

The Cometic MLS Cylinder Head Gasket is designed as a direct replacement for factory gaskets on select Ram 1500, 2500, and 3500 models from 2014 through 2019. It fits a variety of engines including the 3.0L EcoDiesel, 3.6L V6, 5.7L Hemi, 6.4L 392, and 6.7L Diesel. Installation requires standard head gasket replacement procedures with no special modifications or sealants needed, making it suitable for professional mechanics and experienced DIYers alike.

Proper surface preparation and torque specifications should be followed to ensure optimal sealing and longevity. This gasket is compatible with the World Products Man-o-War engine block, further emphasizing its suitability for performance and heavy-duty builds.
