What is the advantage of Multi-Layer Steel (MLS) head gaskets?

MLS head gaskets are made of multiple stainless steel layers, which increases their strength and resistance to corrosion. They are also designed to rebound, helping to maintain a strong seal under demanding conditions without needing extra sealants.

What is the role of the Viton coating on the outer layers?

The Viton coating on the outer layers is a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). It helps create a robust seal in harsh environments and works well with various surface finishes on engine blocks and heads.

Does this gasket require any additional sealants for installation?

No, Cometic MLS head gaskets are designed to provide maximum sealing performance on their own and do not require the use of additional sealants. This simplifies the installation process.

About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring an operating thickness of 0.036 inches when compressed. It's specifically designed for high-output engines and is ideal for mating aluminum heads to either aluminum or cast iron blocks, handling the shearing forces that can occur between different metals. The outer layers are coated on both sides with Viton, a heat-resistant rubber material rated up to 482°F (250°C), which is tough enough for demanding sealing environments and various surface finishes. The center layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine needs.

Because it's constructed from multiple layers of stainless steel, these MLS gaskets offer increased strength and the ability to rebound, helping to resist corrosion. They are designed to provide maximum sealing performance without the need for additional sealants, making installation more straightforward. This particular gasket has an 81mm bore and a 0.120-inch thickness, making it a solid option for rebuilding or upgrading the top end of your 4A-GE 20-valve engine.
