Cometic Gasket | High-Performance MLS Head Gaskets
The ultimate sealing solution for high-horsepower Australian builds. At Chicane Australia, we provide specialised supply for Cometic Gasket. Known for pioneering Multi-Layer Steel (MLS) technology, Cometic gaskets provide the superior torque retention and thermal load resistance required for turbocharged and high-compression engines. We facilitate fast sourcing and reliable delivery across Australia for their entire performance sealing catalogue.
MLS Technology & Precision Sealing
Cometic MLS (Multi-Layer Steel) gaskets are comprised of multiple layers of stainless steel, with the outer layers embossed and coated with a specialized Viton rubber material. This design allows the gasket to act like a spring, maintaining a consistent seal even as the cylinder head and block expand and contract at different rates. For high-boost applications like a **Ford Barra** or **Nissan RB26**, this technology is essential to prevent head gasket failure under extreme cylinder pressures.
Our sourcing capabilities cover the primary Cometic performance range:
• MLS Head Gaskets: Available in a vast array of bore sizes and thicknesses to suit everything from the Toyota 2JZ to the GM LS and Subaru EJ/FA platforms.
• Custom Thickness Gaskets: Critical for engine builders needing to correct deck height or fine-tune compression ratios after machining.
• Street Series & Racing Intake/Exhaust Gaskets: High-temperature manifold gaskets designed to eliminate leaks in high-vibration environments.
• Complete Engine Gasket Kits: All-in-one solutions for total engine overhauls, ensuring every seal meets motorsport standards.
Based on the Central Coast, NSW, we provide the technical expertise to ensure you select the correct gasket specifications for your engine's surface finish (RA) and power goals. We work closely with our supply network to ensure your Cometic hardware is sourced and despatched with professional care and speed.
Cometic Gasket FAQ
What surface finish is required for a Cometic MLS gasket?
For a Cometic MLS gasket to seal correctly, the cylinder head and block surfaces must be clean and flat with a smooth surface finish. Cometic recommends a surface finish of 50 RA (Roughness Average) or finer. If the surface is too rough, the Viton coating may not be able to fill the microscopic peaks and valleys, leading to potential leaks.
Do Cometic MLS gaskets require copper spray?
No. Cometic MLS gaskets are designed to be installed "dry." They come pre-coated with a specialized Viton rubber material that is engineered to bond to the mating surfaces during the heat cycle. Adding copper spray or other sealants can actually interfere with this coating and cause premature failure.
How quickly can you source Cometic gaskets?
We utilise a robust international and local supply network to provide the fastest possible turnaround. Most Cometic MLS head gaskets for popular Australian platforms are sourced and despatched within a short timeframe for delivery across Australia.
