Key Features
Cometic’s MLS head gasket incorporates advanced materials and design elements to meet the challenges of high-stress engines:
- Constructed from multiple embossed layers of stainless steel for superior strength and durability
- Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F), ensuring excellent sealing under extreme temperatures
- Compressed operating thickness of 0.036" for precise fit and optimal sealing performance
- Designed to accommodate aluminum-to-aluminum and aluminum-to-cast iron engine configurations, resisting shearing forces caused by thermal expansion differences
- Corrosion-resistant materials extend gasket life and maintain seal integrity over time
- No additional sealants required, simplifying installation and reducing potential failure points
- Center shim layer of uncoated stainless steel allows for thickness customization to meet specific engine requirements
- Precision bore size of 4.120" tailored for Chrysler 6.4L Apache Gen-3 Hemi engines
Construction & Design
The Cometic MLS head gasket features a robust multi-layer steel construction, combining several embossed stainless steel layers to provide exceptional strength, flexibility, and sealing capability. The outer layers are coated with Viton, a high-performance rubber compound known for its resistance to heat, chemicals, and wear. This coating ensures a tight seal even under harsh operating conditions and varying surface finishes.
Its design expertly compensates for the differential expansion rates between aluminum cylinder heads and cast iron or aluminum engine blocks, preventing leaks caused by thermal cycling and mechanical stress. The uncoated stainless steel shim layer in the center allows for precise thickness adjustments, ensuring a perfect fit and optimal compression ratio for your engine’s specific needs.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
