What is the compressed thickness of this head gasket?

The compressed operating thickness for this Cometic MLS head gasket is 0.040 inches. This measurement is important for ensuring proper compression ratio and valve-to-piston clearance after installation.

Does this head gasket require any sealant?

No, this Multi-Layer Steel (MLS) head gasket from Cometic is designed to provide maximum sealing performance without the need for any 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 rubber material, a type of fluoroelastomer, that can withstand high temperatures up to 482°F. It's used on the outer layers of this gasket to create a durable and reliable seal against the cylinder head and engine block, even in demanding operating conditions.

About this part

Product Details

When you're rebuilding the top end of your KA24DE engine, a solid head gasket is crucial for sealing the combustion chambers and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built with multiple embossed stainless steel layers, giving it the strength to handle the pressures of a high-output engine. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F, ensuring a reliable seal against the cylinder head and block.

The compressed operating thickness of this gasket is 0.040 inches, and the bore size is 90mm, making it a direct fit for your 1991-1998 Nissan 240SX. MLS gaskets are a great choice for both aluminum-to-aluminum and aluminum-to-cast iron setups because they can manage the different expansion rates of those materials. The stainless steel construction also means it can rebound and resist corrosion, while the Viton coating is designed to work in tough sealing environments and on various surface finishes.

Because it's an MLS design, this gasket doesn't require any additional sealants, simplifying the installation process. It's a well-built component designed to provide maximum sealing performance for your engine.
