What is a Multi-Layer Steel (MLS) head gasket?

An MLS head gasket is constructed from several layers of stainless steel. This design offers increased strength and durability compared to single-layer gaskets, and it's built to handle the high pressures and temperatures found in modern engines.

Why is Viton coating used on this gasket?

Viton is a type of synthetic rubber that is highly resistant to heat and harsh chemicals. Coating the gasket with Viton helps ensure a strong, reliable seal in demanding engine environments and can withstand temperatures up to 482°F (250°C).

Do I need to use any sealant with this head gasket?

No, this Cometic MLS head gasket is designed to provide a complete seal on its own and does not require any additional sealants. The embossed layers and Viton coating create the necessary sealing surfaces.

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. If you're working on the B21A1 engine in your 1990 or 1991 Honda Prelude, this gasket is designed to provide a reliable seal for your cylinder head.

This gasket is built with multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing conditions and works well with both aluminum and cast iron engine blocks. The compressed thickness is 0.045 inches, and it's made for an 83mm bore, fitting your Prelude's B21A1 engine precisely. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward.
