Overview

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is a premium replacement part engineered specifically for the 4.7L PowerTech V8 engines found in select Jeep and Dodge models from 1999 through 2005. Designed to provide a reliable and durable seal between the cylinder head and engine block, this gasket is ideal for both daily drivers and performance enthusiasts who demand consistent engine integrity under a variety of operating conditions.

Built to withstand the thermal and mechanical stresses of aluminum-to-aluminum and aluminum-to-cast iron engine configurations, this gasket ensures a leak-free seal that resists blowouts and gasket failure. Whether you are performing an engine rebuild, repair, or upgrade, the Cometic MLS gasket delivers dependable performance without the need for additional sealants.

Key Features

Cometic’s MLS Cylinder Head Gasket incorporates advanced materials and design elements to maximize sealing performance and longevity:

• Multiple embossed layers of stainless steel for enhanced strength and flexibility
• Outer layers coated with Viton rubber for superior heat resistance and chemical durability
• Compressed operating thickness of 0.045 inches optimized for precise sealing
• Embossed outer layers improve gasket sealing under high clamping loads
• Center shim layer of uncoated stainless steel tailored for exact thickness and durability
• Resistant to corrosion and engineered to rebound, maintaining a tight seal over time
• Designed to withstand shearing forces between aluminum heads and cast iron blocks
• No sealants required, simplifying installation and reducing potential failure points

Construction & Design

The Cometic MLS gasket features a robust multi-layer steel construction that combines the strength of stainless steel with the resilience of Viton rubber coatings. The outer layers consist of embossed stainless steel coated on both sides with Viton, a high-performance fluorocarbon elastomer known for its exceptional heat resistance up to 250°C (482°F) and chemical stability. This ensures the gasket maintains a reliable seal even in harsh engine environments.

At the core lies an uncoated stainless steel shim layer that provides structural integrity and allows for precise thickness customization to meet specific engine requirements. This layered design effectively absorbs and compensates for thermal expansion differences between aluminum cylinder heads and cast iron blocks, preventing leaks and gasket failure under extreme conditions.
