Product Details

Starting with a .043 inch thickness, these Cometic exhaust manifold gaskets are built for Oldsmobile Gen-2 Rocket V8 engines. They are constructed from multiple layers of stainless steel, chosen for its strength, ability to rebound, and resistance to corrosion. This well-built design helps ensure a solid seal for your exhaust system.

The outer layers of the gasket are embossed and coated with a Viton rubber material on both sides. This coating is designed to handle a variety of harsh sealing environments and surface finishes, and it's heat resistant up to 482°F. This means you get a dependable seal that can stand up to the heat and pressure of your V8 engine. A notable benefit is that these gaskets do not require any additional sealants, making installation more straightforward.
