What is the compressed thickness of this head gasket?

This Cometic head gasket has a compressed operating thickness of 0.098 inches. This measurement is critical for ensuring proper compression ratios and valve train geometry after installation.

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

No, this Cometic Multi-Layer Steel (MLS) head gasket is designed to provide maximum sealing performance without the need for additional sealants. The Viton coating on the outer layers ensures a reliable seal on its own.

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

Viton is a heat-resistant synthetic rubber material capable of withstanding high temperatures, up to 482°F (250°C). It's used on the outer layers of this gasket to create a durable and effective seal against the cylinder head and engine block, even under demanding operating conditions.

About this part

Product Details

If you're rebuilding the top end of your 2011-2018 Ram 2500 with the 6.7L Cummins engine, a solid head gasket is crucial for sealing combustion pressures. This Cometic MLX head gasket is built to handle the demands of these high-output diesel engines.

This gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating ensures a strong seal against the cylinder head and block, even with dissimilar metals like aluminum heads and cast iron blocks. The center layer is stainless steel and can be varied for different thickness requirements; this particular gasket has a compressed thickness of 0.098 inches and a bore size of 4.312 inches, designed specifically for the 6.7L Cummins ISB engine.

Because it's a Multi-Layer Steel (MLS) gasket with Viton coating, it doesn't require any additional sealants, making installation more straightforward. It's a well-built component designed for reliable sealing in demanding diesel applications.
