What is Viton and why is it used on this gasket?

Viton is a type of synthetic rubber that is highly resistant to heat, withstanding temperatures up to 482°F. It's used on the outer layers of this gasket to ensure a strong, reliable seal in demanding engine conditions.

Do I need to use any sealant with this head gasket?

No, this Cometic MLS-5 head gasket is designed to provide maximum sealing performance without the need for any additional sealants. The multi-layer steel construction and Viton coating handle the sealing requirements.

What does 'MLS-5' mean in the product name?

About this part

Product Details

Cometic Gasket is well-known for making robust sealing solutions for high-performance engines. This MLS-5 head gasket is built for Ford SB engines, specifically designed to work with AFR heads and featuring a 4.155 inch bore with a compressed thickness of 0.060 inches. It fits a wide range of Ford vehicles, including models like the Ford Bronco, Ford F-100, and AC Shelby Cobra, among many others.

This gasket uses a Multi-Layer Steel (MLS) construction, which means it's made of several layers of stainless steel. This design gives it increased strength and the ability to resist corrosion, while also allowing it to rebound and maintain a seal under stress. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating ensures a strong seal even in harsh conditions and across different surface finishes, and the gasket doesn't require any additional sealants.
