An Exhaust Outlet Connection Gasket, also known as a flange gasket, is a seal that sits between the exhaust outlet connection and the exhaust system. The gasket acts as a barrier to prevent exhaust gases from escaping and entering other parts of the truck or environment. Made from high-quality materials, such as metal or rubber, this gasket provides a tight seal to ensure proper engine performance and reduce emissions. When replacing an Exhaust Outlet Connection Gasket, it is important to select the correct part number to ensure compatibility with your specific truck model.
