What does .030 inch undersize mean for this gasket?

The .030 inch undersize designation means the gasket's port opening is slightly smaller than the standard size. This is often used when cylinder heads or exhaust manifolds have been machined or resurfaced, or to ensure a tighter seal on the exhaust port.

Can these gaskets be reused?

Multi-Layer Steel (MLS) gaskets like these are generally designed for single use. They compress to seal the surfaces, and attempting to reuse them can compromise the seal and lead to leaks.

What temperature can these gaskets withstand?

These Cometic exhaust gaskets are rated to withstand temperatures up to 2000 degrees Fahrenheit, making them suitable for the high heat generated by exhaust systems.

Product Details

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) exhaust gasket is a prime example. It's specifically made for Ford 4.6L and 5.4L 3-valve modular V8 engines, and this particular set is .030 inch undersize, designed to seal exhaust ports on a range of vehicles like the Ford F-150, Crown Victoria, and Lincoln Town Car from the mid-2000s through early 2010s.

These gaskets are built to handle the heat, rated for temperatures up to 2000F, which is crucial for exhaust components. The MLS construction means they are designed to be compressible, allowing them to seal effectively even if your exhaust manifold or cylinder head sealing surfaces aren't perfectly flat. This makes them a solid option when you're rebuilding or replacing exhaust components on these popular Ford engines.
