Product Details
This is a Cometic Multi-Layer Steel (MLS) cylinder head gasket specifically made for the 1990 and 1991 Honda Prelude with the B21A1 engine. A head gasket is crucial because it seals the combustion chamber and coolant passages between the engine block and cylinder head, preventing leaks and maintaining compression.
Cometic builds this gasket with three to five layers of stainless steel. They chose stainless steel for its strength, its ability to spring back after compression, and its resistance to corrosion. The outer layers of the gasket are embossed and then coated on both sides with a Viton rubber material. This coating is designed to handle tough sealing jobs, various load conditions, and different surface finishes on your engine block and head. The Viton coating can withstand temperatures up to 482°F (250°C), making it suitable for the heat generated in an engine.
