Cometic H1521040S MLS Head Gasket 95mm Bore .040" Thickness

The Cometic H1521040S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for precision sealing in demanding automotive applications. This gasket features a 95mm bore diameter and .040" compressed thickness, making it ideal for engine builds requiring specific compression ratios and custom clearances.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 95mm bore diameter for precise fitment
• .040" (1.02mm) compressed thickness for compression ratio tuning
• Advanced material composition resists extreme temperatures and pressures
• Micro-sealing embossments conform to deck surface imperfections
• Reusable design when properly installed and torqued
• Ideal for turbocharged, supercharged, and high-compression naturally aspirated engines

Cometic MLS gaskets are manufactured using multiple layers of stainless steel with a viton rubber coating, providing exceptional recovery and torque retention. The layered design allows the gasket to adapt to flange movement and surface irregularities while maintaining a reliable seal. Each gasket is sold individually and requires proper surface preparation (RA finish 50-60 recommended) for optimal performance.
