Cometic H1796SP1051S MLS Head Gasket with Oil Holes

The Cometic H1796SP1051S is a high-performance Multi-Layer Steel (MLS) head gasket designed for enthusiasts who demand superior sealing and durability. This gasket features both additional oil holes for improved lubrication management in modified applications.

MLS Construction:

This three-layer MLS gasket is constructed from premium stainless steel for maximum strength, excellent rebound characteristics, and superior corrosion resistance. The outer layers are precisely embossed and coated on both sides with Viton, a fluoroelastomer rubber-based material engineered to withstand extreme sealing environments, varying load conditions, and different surface finishes. The Viton coating maintains its sealing integrity at temperatures up to 482°F (250°C).

Key Features:

• Three-layer stainless steel MLS construction for enhanced durability
• Both additional oil holes included for modified engine applications
• Viton-coated outer layers for superior heat and chemical resistance
• Uncoated stainless steel center shim layer allows for precise thickness tuning
• Ideal for aluminum-to-cast iron and aluminum-to-aluminum block applications
• Withstands shearing forces between dissimilar metals
• No re-torque required after installation
• Promotes even torque distribution to minimize bore distortion

The center shim layer remains uncoated and can be varied in thickness to meet specific compression requirements. This MLS design effectively handles the thermal expansion differences and shearing forces created when using aluminum heads on cast iron blocks, while promoting even torque loading across the entire sealing surface for measurably reduced bore distortion.
