Cometic H1796SP6040S MLS Head Gasket Bore Thickness - 96.04mm 040

The Cometic H1796SP6040S is a Multi-Layer Steel (MLS) cylinder head gasket engineered for high-performance applications. Designed to meet the demanding requirements of modified engines, this gasket provides superior sealing, durability, and reliability under extreme conditions.

Multi-Layer Steel Construction:

This MLS gasket features three layers of stainless steel construction for maximum strength and durability. The outer layers are embossed and coated on both sides with Viton, a fluoroelastomer rubber-based material that excels in harsh sealing environments. This coating is heat resistant up to 250°C (482°F) and provides excellent resistance to coolants, oils, and corrosive substances. The center shim layer consists of uncoated stainless steel, which determines the gasket's overall thickness and can be customized for specific compression requirements.

Key Features:

• Three-layer stainless steel construction for superior strength and rebound characteristics
• Viton-coated outer layers for exceptional chemical and heat resistance
• .040" (1.02mm) compressed thickness for precise compression ratio tuning
• 96.04mm bore diameter for exact fitment
• Ideal for aluminum heads to cast iron blocks or aluminum-to-aluminum applications
• Withstands shearing forces created by dissimilar metals
• No re-torque required after initial installation
• Promotes even torque load distribution to reduce bore distortion
• Corrosion-resistant stainless steel construction

Cometic MLS head gaskets are the choice of professional engine builders and performance enthusiasts who demand precise fitment, reliable sealing, and the ability to withstand high cylinder pressures and temperatures. The advanced multi-layer design compensates for head and block surface imperfections while maintaining consistent sealing pressure across the entire combustion chamber.
