Cometic C8736-018 MLS Head Gasket Bore - 68.5mm 018 Inch

The Cometic C8736-018 is a Multi-Layer Steel (MLS) head gasket with C.O.T. (Coated) construction, featuring a .018 inch compressed thickness and 68.5mm bore diameter. This gasket is constructed from multiple layers of stainless steel for additional strength over traditional gaskets.

Key Features:

• Multi-Layer Steel design features an active combustion seal on multiple layers
• Load-controlled embossments help conform load distribution across the sealing area
• Each MLS head gasket is coated with a .001 inch thick Viton rubber bonded to the outer stainless steel layers
• Creates an exceptional seal by requiring less clamp load and resulting in less bore distortion
• Goes on dry with no additional sealant or re-torque required when properly installed
• 68.5mm bore diameter optimized for specific engine applications
• .018 inch compressed thickness for precise compression ratio control

Installation Requirements:

• Surface finish of 50 RA (roughness average) or finer is recommended for proper seal
• Requires smooth, flat and true head and deck surfaces to seal properly
• Always refer to fastener manufacturer for accurate torque values

The stainless-steel outer layers utilize a rubber-binder coating that features high-temperature and chemical-resistant polymers, making this gasket ideal for high-performance and demanding applications. Cometic's MLS technology provides superior sealing performance for engines requiring precise combustion chamber sealing.
