What is the compressed thickness of this head gasket?

The compressed operating thickness of this Cometic head gasket is 0.036 inches. This is achieved through the multi-layer steel construction, with the specific .089 inch thickness referring to its uncompressed state.

Do I need to use any sealant with this gasket?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. The Viton coating on the outer layers helps ensure a solid seal.

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

Viton is a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). It's used on the outer layers of this gasket to meet the demands of harsh sealing environments, load conditions, and various surface finishes found in high-output engines.

About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It’s designed for Dodge 5.7L HEMI engines with a 4.100-inch bore and a thickness of .089 inches. This gasket is built to handle the demands of high-output engines, ensuring a solid seal between your cylinder head and engine block.

This gasket is constructed from multiple layers of stainless steel, which gives it strength and the ability to rebound, helping it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is crucial for meeting the demands of harsh sealing environments and different surface finishes, making it suitable for both aluminum and cast iron blocks. The center layer is stainless steel and can be varied to achieve different thicknesses, like the .089 inches on this specific gasket.

This gasket fits a wide range of vehicles, including models like the Dodge Charger, Jeep Grand Cherokee, and Ram 1500. It's designed to provide maximum sealing performance without needing additional sealants, simplifying installation.
