Product Details
Cometic Gasket is a well-known name for its multi-layer steel (MLS) head gaskets, built to handle the demands of high-output engines. This particular gasket, part number C5721-051, is designed for the right side of Buick 3800 Series II and III V6 engines, featuring a 3.840-inch bore and a compressed thickness of 0.051 inches. It fits a wide range of vehicles, including models like the Buick LeSabre, Chevrolet Camaro, and Pontiac Grand Prix.
This MLS gasket is constructed from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. This construction means the gasket seals effectively without needing additional sealants, making it suitable for combinations of aluminum heads with aluminum or cast iron blocks. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses, like the 0.051 inches specified for this part.
