What does the .030in designation mean for this gasket set?

The .030in designation refers to the thickness of the center shim layer of the Multi-Layer Steel (MLS) gasket. This thickness is often chosen to accommodate engine builds where surfaces may have been machined or to achieve specific compression ratios.

Do I need to use any sealant with these gaskets?

No, these Cometic MLS gaskets are designed to provide maximum sealing performance without the need for additional sealants. The embossed outer layers coated with Viton create a robust seal on their own.

What is Viton and why is it used on these gaskets?

Viton is a heat-resistant synthetic rubber material. It's used here because it can withstand high temperatures and harsh sealing environments, ensuring a reliable seal for exhaust manifolds under demanding conditions.

Product Details

Cometic Gasket is known for making well-built sealing solutions, and this Chrysler B/RB .030in exhaust manifold gasket set is no exception. If you're working on a classic Mopar with a B or RB engine, getting a solid seal on your exhaust manifolds is key to keeping performance up and noise down. This gasket set is designed to handle the heat and pressure that comes with those engines.

This gasket set is made from Multi-Layer Steel (MLS), which means it's built with several layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant material that can handle tough sealing environments and different surface finishes. The center layer is uncoated stainless steel and can be varied in thickness to meet specific needs; in this case, it's set at .030 inches to accommodate engine builds that might need a bit more clearance or have had surfaces machined. The ports measure 1.780 inches by 1.460 inches, fitting a range of Chrysler, Dodge, and DeSoto vehicles from the late 50s through the late 70s, like the Chrysler New Yorker, Dodge Charger, or DeSoto Adventurer.
