Walker 31331 Exhaust Pipe Flange Gasket

Walker 31331 Exhaust Pipe Flange Gasket

Walker 31331 is a steel ring-style exhaust pipe flange gasket built for sealing exhaust joints in OE-style repair applications. With a 2.000-inch inside diameter, 2.250-inch outside diameter, and 0.12-inch thickness, it is sized for specific flange connections where a tight seal is needed to control exhaust leakage.

Use this gasket for select Acura, Honda, Isuzu, and Buick exhaust repairs, including applications such as a 2004-2008 Acura TL Y-pipe to left muffler assembly or a 1995-1998 Honda Odyssey muffler assembly to tail pipe connection. Walker 31331 is also a direct-fit option for other listed flange-to-flange exhaust joints across the 1992-2017 model years.
