Cometic H1912SP1030S MLS Head Gasket 1.030" Bore

The Cometic H1912SP1030S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for demanding sealing applications. Designed for performance enthusiasts who require precise sealing solutions, this gasket delivers superior durability and reliability under extreme conditions.

Multi-Layer Steel Construction:

This MLS head gasket features a three-layer stainless steel design that provides exceptional strength, superior rebound characteristics, and excellent corrosion resistance. The outer layers are embossed and coated on both sides with Viton, a fluoroelastomer rubber-based material that withstands temperatures up to 482°F (250°C). This advanced coating is engineered to handle harsh sealing environments, varying load conditions, and different surface finishes.

Key Features:

• Three-layer stainless steel construction for maximum durability
• Viton coating on outer layers for superior heat and chemical resistance
• Center shim layer allows for precise thickness customization
• Ideal for aluminum-to-cast iron and aluminum-to-aluminum applications
• Withstands shearing forces from dissimilar metal combinations
• No re-torque required after installation
• Promotes even torque distribution for reduced bore distortion
• Excellent resistance to coolants and oils

The uncoated stainless steel center layer serves as a shim that can be adjusted to meet specific thickness requirements. The MLS design effectively handles the thermal expansion differences between aluminum heads and cast iron blocks, while promoting uniform clamping force across the entire sealing surface to minimize cylinder bore distortion.
