Cometic C10286-HB-045-014 MLS Head Gasket Bore Thick - 4.290 045

The Cometic C10286-HB-045-014 is a high-performance multi-layer steel (MLS) head gasket designed for demanding engine applications. This gasket features a 4.290-inch bore diameter and .045-inch compressed thickness, making it ideal for high-compression and forced induction builds.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 4.290-inch bore diameter for precise fitment
• .045-inch compressed gasket thickness
• .014-inch raised combustion seal (RC) for enhanced combustion chamber sealing
• Integrated oil and coolant passage sealing
• Viton rubber gasket material for oil and coolant sealing rings
• Stainless steel construction resists corrosion and withstands extreme temperatures
• Engineered for high-performance, turbocharged, and supercharged applications

Cometic MLS head gaskets utilize multiple layers of stainless steel with embossed sealing beads to maintain consistent clamping pressure across the entire sealing surface. The raised combustion seal provides additional sealing strength around the combustion chamber, critical for high-boost and high-compression engines. This gasket is designed to handle extreme cylinder pressures while maintaining proper oil and coolant sealing throughout the engine's operating range.
