Cometic H1749-SPA030S MLS Head Gasket 0.030" Thick

The Cometic H1749-SPA030S is a high-performance Multi-Layer Steel (MLS) head gasket engineered for demanding racing and performance applications. Designed with precision and durability in mind, this gasket delivers superior sealing capabilities for modified engines operating under extreme conditions.

Multi-Layer Steel Construction:

• Three-layer stainless steel design provides exceptional strength and rebound characteristics
• Outer layers feature embossed construction with Viton fluoroelastomer coating on both sides
• Viton coating resists heat up to 482°F (250°C) and withstands harsh sealing environments
• Center shim layer uses uncoated stainless steel for precise thickness control
• 0.030" compressed thickness for specific bore and compression requirements

Performance Benefits:

• Ideal for aluminum head to cast iron block and aluminum head to aluminum block applications
• Withstands shearing forces created by dissimilar metal expansion rates
• Promotes even torque distribution across sealing surface to reduce bore distortion
• No re-torque required after initial installation
• Corrosion-resistant stainless steel construction ensures long-term reliability

Cometic MLS gaskets are the choice of professional engine builders and performance enthusiasts who demand reliable sealing under high boost, extreme cylinder pressures, and elevated temperatures. Each gasket is manufactured to exacting specifications to ensure consistent quality and performance.
