Cometic H1749SP3030S MLS Head Gasket Bore Thickness - 87mm 030

The Cometic H1749SP3030S is a high-performance multi-layer steel (MLS) head gasket engineered for demanding automotive applications. Designed with precision for enthusiasts who require reliable sealing under extreme conditions, this gasket delivers superior performance for both aluminum and cast iron engine combinations.

Multi-Layer Steel (MLS) Construction:

• Three-layer stainless steel design provides exceptional strength and rebound characteristics
• Outer layers feature embossed surfaces coated with Viton fluoroelastomer material on both sides
• Viton coating withstands temperatures up to 250°C (482°F) for extreme heat resistance
• Center shim layer allows for precise thickness customization
• Corrosion-resistant stainless steel construction ensures long-term durability

Performance Benefits:

• Promotes even torque load distribution across the sealing surface
• Reduces bore distortion for improved cylinder seal and performance
• Withstands shearing forces between dissimilar materials (aluminum to cast iron)
• No re-torque required after installation
• Ideal for both aluminum-to-aluminum and aluminum-to-cast iron applications
• Excellent sealing against coolants, oils, and combustion gases

This gasket is specifically designed to meet the individual requirements of performance engines where reliability and precision are critical. The MLS technology ensures consistent sealing even under high boost, elevated temperatures, and extreme cylinder pressures.
