Cometic H1935SP9051S MLS Head Gasket Multi-Layer Steel High-Performance

The Cometic H1935SP9051S is a multi-layer steel (MLS) cylinder head gasket engineered for high-performance street and racing engine applications. Cometic is a globally recognized manufacturer of precision sealing solutions trusted by professional engine builders and motorsports teams across drag racing, road racing, and high-output street builds.

This MLS head gasket is constructed from multiple embossed layers of stainless steel, with outer layers coated in FKM (Viton®) fluoroelastomer rubber—a high-temperature, chemical-resistant polymer that creates a reliable micro-seal against both coolant and oil intrusion. The center shim layer is uncoated stainless steel, allowing thickness to be precisely controlled to suit specific compression and quench requirements. Load-controlled embossments distribute clamping force evenly across the sealing surface, reducing bore distortion compared to traditional composite gaskets.

Key Features:

• Multi-layer stainless steel (MLS) construction for maximum strength and durability
• FKM (Viton®) coated outer layers for superior resistance to heat, coolant, and oil
• PTFE topcoat aids in fret resistance and improves cold sealing performance
• Load-controlled embossments promote even clamp load distribution and reduced bore distortion
• No sealants or re-torque required for installation
• Suitable for aluminum-to-cast-iron and aluminum-to-aluminum head/block combinations
• Precision-manufactured to tight tolerances for consistent, long-lasting sealing
• Ideal for both street performance and full race applications

Cometic MLS head gaskets are manufactured at the company's state-of-the-art facility and are a proven choice for engine builders demanding reliable, repeatable sealing performance in demanding, high-output applications.
