Cometic H1935SP9040S MLS Head Gasket Bore Thickness - 90.4mm 040

The Cometic H1935SP9040S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for demanding sealing applications. This gasket features a 90.4mm bore diameter with a .040" (1.02mm) compressed thickness, designed to meet the specific requirements of performance and racing engines.

Multi-Layer Steel (MLS) Construction:

• Three-layer design utilizing stainless steel for superior strength, rebound characteristics, and corrosion resistance
• Outer layers embossed and coated with Viton fluoroelastomer material on both sides for exceptional sealing performance
• Viton coating withstands extreme temperatures up to 250°C (482°F)
• Uncoated stainless steel center shim layer provides structural integrity and precise thickness control
• Engineered to handle harsh sealing environments, varying load conditions, and different surface finishes

Performance Benefits:

• Ideal for aluminum head to cast iron block and aluminum head to aluminum block applications
• Withstands shearing forces created by dissimilar metal combinations
• Promotes even torque load distribution across the sealing surface for reduced bore distortion
• No re-torque required after installation
• Excellent resistance to coolants, oils, and combustion gases

This gasket is perfect for performance enthusiasts seeking reliable, high-quality sealing solutions for modified and high-output engines.
