Cometic C4045 MLS Head Gasket Compressed Thickness - 027

The Cometic C4045 is a Multi-Layer Steel (MLS) cylinder head gasket featuring a .027-inch compressed thickness, engineered to provide maximum sealing performance for high-output engines. This gasket is constructed from multiple layers of stainless steel, offering superior strength and durability compared to traditional head gaskets.

Key Features:

• Multi-layer stainless steel construction for enhanced strength and rebound ability
• .027-inch compressed operating thickness for precise compression control
• Outer layers embossed and coated with Viton (FKM rubber) for high-temperature and chemical resistance
• Load-controlled embossments provide improved load distribution across the sealing area
• Reduces bore distortion and requires less clamp load for exceptional sealing
• No sealants or re-torque required when properly installed on prepared surfaces
• Ideal for both aluminum-to-aluminum and aluminum-to-cast iron applications
• Resistant to corrosion and designed to withstand shearing forces between dissimilar materials

Cometic MLS gaskets feature an active combustion seal on multiple layers, with a stainless steel center layer sandwiched between viton-coated spring steel embossed outer layers. This advanced design creates a superior seal that meets the demands of various harsh sealing environments, load conditions, and surface finishes without the need for additional sealants.
