Description

Mr. Gasket CopperSeal exhaust gaskets are made from .043 in. thick solid copper, and are track-proven to eliminate exhaust leaks in Top Fuel Dragster, Funny Car, and Alcohol class race cars. These gaskets feature an embossed O-ring design to increase sealing pressure around the exhaust ports, creating a tight, leak-proof seal. They're also ideal for tow vehicles and motor homes. CopperSeal gaskets are available in a variety of port styles, as well as more than a dozen size configurations. Order the model designed for precise fitment with your exhaust header.
