What is the compressed thickness of this head gasket?

The compressed operating thickness of this Cometic MLS head gasket is 0.080 inches. This measurement is important for ensuring proper compression ratios and valve-to-piston clearance.

Does this gasket require any additional sealants?

No, Cometic MLS (Multi-Layer Steel) head gaskets are designed to provide maximum sealing performance on their own and do not require any additional sealants. The Viton rubber coating on the outer layers ensures a tight seal.

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

Viton is a heat-resistant synthetic rubber material that can withstand high temperatures, up to 482°F (250°C). It's used on the outer layers of this gasket to create a robust seal that can handle the demanding conditions found in modern engines.

About this part

Product Details

This product is a Cometic Multi-Layer Steel (MLS) head gasket designed for non-turbo Nissan L28E, L28S, and L28ES engines from 1975 through 1980. It features an 89mm bore and a compressed thickness of .080 inches. MLS gaskets are known for their robust construction, using multiple layers of stainless steel to create a strong seal that can handle the demands of high-output engines without needing additional sealants. This makes them a solid choice for applications with aluminum heads paired to either aluminum or cast iron blocks, as they can manage the different expansion rates between these materials.

The outer layers of this gasket are embossed and coated on both sides with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit. This coating is designed to perform well in harsh sealing environments and under various load conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements. The multi-layer design not only adds strength but also allows the gasket to rebound and resist corrosion, contributing to its durability and reliable performance.
