Cometic C15719-040 MLS Cylinder Head Gasket Thickness - 040

The Cometic C15719-040 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket with a 0.040-inch compressed thickness. Designed for high-performance and racing applications, this gasket delivers superior sealing integrity under extreme cylinder pressures, elevated temperatures, and high-boost forced induction environments.

Key Features:

• Multi-Layer Steel (MLS) construction — multiple embossed stainless steel layers provide consistent, reliable sealing across the entire head surface
• 0.040" (1.02mm) compressed thickness — allows precise control of compression ratio and squish clearance
• Proprietary high-temperature coating — chemically resistant surface treatment protects against coolant, oil, and combustion gases
• Corrosion-resistant stainless steel alloy — selected for tensile strength, yield strength, and long-term durability
• Manufactured in the USA using domestically sourced materials
• Part of Cometic's Performance Gasket Line — trusted by NASCAR and professional racing teams

Cometic's MLS head gaskets are ideal for high-compression builds, turbocharged, supercharged, and nitrous oxide applications where OEM gaskets cannot maintain a reliable seal. Each gasket is manufactured to exacting tolerances to ensure consistent bore geometry and proper torque retention across the sealing surface.
