• Multi-layer steel (MLS) construction with multiple embossed stainless steel layers for enhanced strength and sealing capability
• Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F) for superior sealing under harsh conditions
• Compressed operating thickness of 0.036 inches, optimized for precise fit and durability
• Designed to withstand the shearing forces between aluminum and cast iron components
• Corrosion-resistant materials ensure long-lasting performance and reliability
• Embossed outer layers improve gasket sealing by conforming to surface irregularities
• Center shim layer of uncoated stainless steel allows for thickness customization and consistent sealing pressure
• Compatible with high-output engines including the Chrysler 6.4L Apache Gen-3 Hemi
• No sealants required, simplifying installation and reducing the risk of leaks

Construction & Design:

The Cometic MLS Cylinder Head Gasket is meticulously crafted from multiple layers of stainless steel, each embossed to enhance sealing performance. The outermost layers are coated with Viton, a premium fluorocarbon elastomer known for its exceptional heat resistance and chemical durability. This coating ensures the gasket maintains a tight seal even under extreme thermal cycling and pressure conditions.

The core or shim layer is made from uncoated stainless steel, providing structural integrity and allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design enables the gasket to flex and rebound, accommodating the differential expansion rates between aluminum heads and cast iron or aluminum blocks without compromising the seal.
