Cometic H2089SP2045S MLS Head Gasket .045" Thick

The Cometic H2089SP2045S is a multi-layer steel (MLS) cylinder head gasket engineered for high-performance applications. Designed to provide superior sealing and durability under extreme conditions, this gasket is ideal for both aluminum-to-cast iron and aluminum-to-aluminum block-to-head combinations.

Multi-Layer Steel Construction:

• Three-layer stainless steel design for maximum strength and corrosion resistance
• Outer layers feature embossed surfaces with Viton fluoroelastomer coating on both sides
• Viton coating withstands temperatures up to 482°F (250°C) for exceptional heat resistance
• Center shim layer allows for precise thickness customization
• Stainless steel construction provides superior rebound characteristics

Performance Benefits:

• Resists shearing forces between dissimilar metals (aluminum heads on cast iron blocks)
• Promotes even torque distribution across the sealing surface
• Reduces bore distortion for improved cylinder sealing
• No re-torque required after installation
• Excellent resistance to coolants, oils, and harsh sealing environments

Cometic gaskets are developed specifically for performance enthusiasts who demand reliable sealing under high-boost, high-compression, and extreme temperature conditions. The MLS design ensures consistent performance across varying load conditions and surface finishes.
