Cometic H1912SPJ051S MLS Head Gasket Bore - 051in

The Cometic H1912SPJ051S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for demanding engine applications. Cometic's MLS gaskets are constructed from multiple layers of embossed stainless steel, providing superior sealing under extreme heat and pressure conditions commonly found in performance, racing, and high-compression engine builds.

Key Features:

• Construction: Multi-Layer Steel (MLS) design for maximum sealing reliability
• Thickness: 0.051 inches compressed thickness
• Material: Stainless steel layers with proprietary coating for enhanced sealing surface conformance
• Design: Precision-cut to OEM specifications with performance tolerances
• Finish: Requires a minimum 63 Ra surface finish on mating surfaces for proper seal

Cometic MLS head gaskets are a preferred choice for engine builders seeking a reliable, reusable-friendly gasket solution that can withstand elevated cylinder pressures from forced induction, nitrous, or high-compression naturally aspirated builds. The multi-layer construction allows the gasket to conform to minor surface imperfections while maintaining a consistent, leak-free seal across the combustion chamber, coolant passages, and oil galleries.

Note: Always verify bore size and thickness compatibility with your specific engine build specifications before installation.
