Detailed Description

Walker 31733 is made for exhaust flange service where a precise seal is needed between mating exhaust components. The graphite body, steel core, and metal fire ring are selected for high-heat exhaust environments, while the 4-bolt layout and listed port dimensions support proper alignment during repair. It is designed to work with OE exhaust components and Walker aftermarket replacement parts, making it a direct-fit service part for many Honda and Acura exhaust applications.

Use Walker 31733 when replacing a worn or leaking flange gasket on vehicles such as the Honda Accord, Odyssey, Pilot, and Ridgeline, as well as Acura RDX, TL, TSX, TLX, MDX, and ZDX models. Walker 31733 is a practical choice for restoring the seal at the exhaust pipe flange without changing the surrounding exhaust assembly.

What It Helps Fix

• Exhaust leaks at the flange connection
• Noise from a failing gasket seal
• Soot marks or odor near the exhaust joint
• Loss of sealing performance after exhaust service
• Fitment issues caused by a damaged or compressed flange gasket

Installation Notes and Tips

Inspect the flange faces for warping, corrosion, or carbon buildup before installation. Clean the mating surfaces thoroughly so the gasket can seat evenly, and verify bolt hole spacing and port dimensions against the existing exhaust joint. For best results, confirm the application against the vehicle’s exhaust configuration before assembly.
