Cometic C8937 MLS Cylinder Head Gasket - 4-Layer 036 Inch

The Cometic C8937 is a Multi-Layer Steel (MLS) cylinder head gasket featuring professional-grade construction with a compressed thickness of .036 inches. This 4-layer design delivers superior sealing performance for high-output engines without requiring additional sealants.

Advanced MLS Construction:

• Four layers of stainless steel construction for exceptional strength and durability
• Outer layers embossed and coated with Viton rubber on both sides for superior sealing
• Viton coating heat resistant to 250°C (482°F) for extreme temperature environments
• Uncoated stainless steel center shim layer maintains precise .036 inch compressed thickness
• Load-controlled embossments distribute clamping force evenly across sealing surface

Performance Benefits:

• Requires less clamp load than traditional gaskets, reducing bore distortion
• Excellent for aluminum-to-aluminum or aluminum-to-cast iron applications
• Withstands shearing forces created by dissimilar material expansion rates
• Enhanced rebound characteristics and corrosion resistance from stainless steel construction
• Install dry—no additional sealant required or recommended

Installation Requirements:

• Surface finish of 50 RA (roughness average) or smoother recommended
• Surfaces must be smooth, flat, and true for proper MLS gasket sealing
• Follow fastener manufacturer torque specifications for proper installation
• No re-torque required when properly installed on prepared surfaces

Cometic MLS gaskets represent the industry standard for high-performance engine sealing, providing maximum reliability for demanding applications across automotive, powersports, marine, and racing markets.
