Cometic H1836SP5040S MLS Head Gasket for Nissan KA24DE 89mm Bore .040 Inch

The Cometic H1836SP5040S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for Nissan KA24DE engines with an 89mm (3.504 inch) bore diameter and .040 inch compressed thickness. This precision-manufactured gasket delivers superior sealing performance for both stock and high-performance engine applications.

Multi-Layer Steel Construction:

This gasket features three layers of stainless steel designed to provide exceptional strength, rebound capability, and corrosion resistance. The outer layers are embossed and coated with Viton (fluoroelastomer), a high-temperature rubber-based material that withstands temperatures up to 482°F and seals effectively under extreme conditions including high cylinder pressures and varying surface finishes. The uncoated center layer can be varied to accommodate different thickness requirements.

Key Features:

• 89mm (3.504 inch) bore diameter for KA24DE engines
• .040 inch compressed gasket thickness
• Three-layer stainless steel MLS construction
• Viton-coated outer layers for superior high-temperature sealing
• Embossed design promotes even torque load distribution
• Reduces bore distortion compared to conventional gaskets
• No re-torque required after installation
• Ideal for aluminum heads on cast iron or aluminum blocks
• Withstands shearing forces from dissimilar metal thermal expansion
• Made in USA with American-manufactured materials

Application Benefits:

Cometic MLS gaskets are engineered to handle the demands of performance engines while providing reliable sealing for street applications. The multi-layer design requires less clamp load than traditional gaskets, resulting in measurably reduced bore distortion and improved cylinder sealing. Perfect for engine rebuilds, performance upgrades, or OEM replacement on Nissan 240SX and other KA24DE-equipped vehicles.
