What is the compressed thickness of this head gasket?

When properly installed and compressed, this head gasket has an operating thickness of 0.036 inches. This is achieved through its multi-layer steel design with a specific center shim layer.

Does this gasket require any special sealants?

No, Cometic's Multi-Layer Steel (MLS) head gaskets are designed to provide maximum sealing performance without the need for additional sealants. The embossed and coated outer layers ensure a reliable seal on their own.

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

Viton is a heat-resistant rubber material that can withstand high temperatures, up to 482°F (250°C). Coating the outer layers of the gasket with Viton helps it meet the demands of harsh sealing environments and maintain a seal under various load conditions and surface finishes.

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 Nissan SR20DE and SR20DET engines, specifically for front-wheel-drive applications with an 87mm bore. This gasket is crucial for maintaining proper compression and preventing leaks between your engine block and cylinder head, especially in higher-output setups.

This MLS gasket uses multiple layers of stainless steel for 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) and works well with various surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements; in this case, it results in a compressed thickness of 0.036 inches. Because it's an MLS design, it doesn't require any additional sealants, making installation more straightforward.

This gasket fits a range of vehicles, including models like the Infiniti G20, Nissan 200SX, and Nissan Sentra. It's a solid option for rebuilding or repairing your engine, ensuring a strong seal for demanding conditions.
