What makes Multi-Layer Steel (MLS) gaskets better for high-pressure engines?

MLS gaskets are constructed from multiple layers of steel, often with a special coating. This layered design allows them to better withstand the extreme pressures and temperatures found in high-performance or heavy-duty diesel engines like the Ford Power Stroke, preventing blowouts and maintaining a consistent seal.

Do I need to use any sealant with these Cometic gaskets?

No, these Cometic MLS exhaust manifold gaskets are designed to be installed without any additional sealants. The materials and construction of the gasket itself create a reliable seal when properly torqued.

What is the significance of the .040 inch thickness?

The .040 inch thickness is a specific measurement for these gaskets, often chosen to compensate for minor surface imperfections or to achieve the correct compression ratio and sealing force for the intended application on the Ford 6.0L and 6.4L Power Stroke engines.

Product Details

Cometic Gasket is known for making well-built gaskets that hold up under tough conditions. This Multi-Layer Steel (MLS) exhaust manifold gasket set is built for Ford 6.0L and 6.4L Power Stroke engines, specifically designed to handle extreme cylinder pressures. These gaskets are .040 inches thick, which is a common size for these applications, and they maintain their torque set without burning through or pushing out.

What's great about these MLS gaskets is that they are designed to work with different combinations of cylinder head and exhaust manifold materials, and they don't require any sealants to do their job. This makes installation more straightforward. They also resist corrosion, helping to ensure a long-lasting seal for your exhaust system.

This gasket set fits a range of Ford Super Duty trucks, including models like the F-250 and F-350 from the early to mid-2000s, as well as the Excursion. If you're working on one of these Power Stroke engines and need a reliable exhaust manifold seal, this set from Cometic is a solid option.
