About this part

Product Details

Starting with a .027 inch thickness and an 83mm bore, this Cometic Multi-Layer Steel (MLS) head gasket is built for the B21A1 engine found in select Honda Civics. MLS gaskets are made from multiple layers of stainless steel, which gives them increased strength and better resistance to corrosion compared to older gasket designs. This construction also helps the gasket rebound effectively under pressure, ensuring a solid seal.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F. This coating is applied to both sides and is designed to work well with various sealing environments and surface finishes, helping to prevent leaks even under demanding conditions. It's a well-built component for rebuilding or replacing your engine's head gasket.
