What is the main benefit of using Viton coating on these gaskets?

The Viton rubber coating on the outer layers is designed to meet the demands of harsh sealing environments and high temperatures. It is heat resistant up to 482°F, ensuring a reliable seal under demanding conditions.

Do I need to use any RTV sealant with these gaskets?

No, these Cometic exhaust manifold gaskets do not require any additional sealants. They are designed to create a proper seal on their own, simplifying the installation process.

What does the .043in thickness refer to?

The .043in measurement refers to the thickness of the gasket itself. This specific thickness is important for proper fitment and sealing within the exhaust manifold system of your AMC V8 engine.

Product Details

When you're working on the exhaust system of your 1971-1974 AMC Javelin, especially with the AMC 304-401 V8 engine, getting a good seal on the exhaust manifolds is crucial. These Cometic copper exhaust manifold gaskets are designed specifically for the dogleg port configuration, helping to prevent exhaust leaks and maintain proper engine performance.

Cometic builds these gaskets with multiple layers of stainless steel, which gives them strength and helps them resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F. This construction means the gasket can handle the tough conditions found around exhaust manifolds without failing. A notable benefit is that these gaskets do not require any additional sealants, making installation more straightforward.
