Cometic H2089SP5045S MLS Head Gasket

The Cometic H2089SP5045S is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered for high-performance applications. Designed to deliver superior sealing under extreme conditions, this gasket is built to handle the demanding requirements of modified and racing engines.

Multi-Layer Steel Construction:

This MLS head gasket features a three-layer stainless steel design that provides exceptional strength, rebound characteristics, and corrosion resistance. The outer layers are precision-embossed and coated on both sides with Viton, a fluoroelastomer rubber-based material that excels in harsh sealing environments and withstands temperatures up to 250°C (482°F). The center shim layer consists of uncoated stainless steel, which can be manufactured in various thicknesses to meet specific compression ratio and deck height requirements.

Key Features:

• Three-layer stainless steel construction for maximum durability
• Viton coating on outer layers resists heat, coolant, and oil
• Ideal for aluminum head to cast iron block or aluminum head to aluminum block applications
• Withstands shearing forces created by dissimilar metal expansion rates
• No re-torque required after installation
• Promotes even torque distribution across sealing surfaces
• Reduces bore distortion for improved ring seal and power

Cometic MLS gaskets are the preferred choice for engine builders and performance enthusiasts who demand reliable sealing in high-boost, high-compression, and extreme temperature environments. The superior design ensures consistent performance and longevity in the most demanding applications.
