Cometic C8609-018 MLS Cylinder Head Gasket .018in. Compressed Thickness

The Cometic C8609-018 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for demanding motorcycle and powersports applications. With a compressed thickness of .018 inches, this gasket delivers a precise, tight combustion seal suited for performance builds requiring a thinner head gasket.

Key Features:

• MLS (Multi-Layer Steel) Construction — multiple layers of stainless steel provide superior strength, spring-back, and corrosion resistance
• .018" Compressed Thickness — ideal for high-compression performance builds
• Viton Rubber Coating — each outer stainless steel layer is coated with a .001" Viton rubber bond for dry installation and an effective seal against combustion gases, coolant, and oil
• Load Control Embossments (LCE) — promote an even torque load across the gasket sealing surface, reducing bore distortion and improving piston ring seal
• Installs Dry — no additional sealant required or recommended
• Made in the U.S.A. — manufactured by Cometic Gasket, a globally recognized leader in high-performance engine sealing

For best results, mating surfaces should be flat and smooth to a surface finish of 50 RA or finer. Always torque fasteners to manufacturer specifications. The Cometic C8609-018 meets and exceeds OEM sealing requirements, making it a trusted choice for professional engine builders and performance enthusiasts.
