Detailed Description

Walker 31310 is an exhaust pipe flange gasket used to restore the seal between mating exhaust flanges. Its 2-bolt layout, 3.500-inch bolt spacing, and 0.500-inch bolt holes make it a direct-fit style sealing component for a range of OE exhaust layouts.

What It Helps Fix

• Exhaust leaks at a two-bolt flange connection

• Soot or odor around the exhaust flange area
• Loss of sealing after flange service or component replacement
• Fitment issues when replacing a worn flange gasket on OE-style exhaust parts

Installation Notes and Tips

Confirm flange spacing, bolt hole diameter, and port dimensions before installation. Clean both mating surfaces thoroughly so the gasket can seat evenly, and inspect the flange faces for warping, corrosion, or pitting that could affect sealing. Match the gasket to the listed exhaust position, such as Y-Pipe To Converter, Front Converter To Rear Converter, or Manifold Converter To Resonator, for the correct application.
