Walker 31729 Exhaust Pipe Flange Gasket

Exhaust Flange Gasket for OE-Style Repair

Walker 31729 is a 4-bolt exhaust pipe flange gasket built for sealing exhaust joints on select Volkswagen and Audi applications. It uses high temperature graphite with a steel core to help maintain a tight seal at the flange connection where heat and vibration are constant.

Use this gasket for exhaust repair on vehicles such as the Volkswagen Tiguan, Volkswagen GTI, Audi A3, and Audi Q3 when the flange connection needs a direct replacement seal.

Detailed Description

Walker 31729 is engineered as an exhaust pipe flange gasket for sealing a 4-bolt exhaust joint. The graphite sealing material helps conform to the flange surface, while the steel core adds support for the demands of exhaust heat cycling and vibration. This makes it a practical choice for restoring a secure seal at the connection point on compatible Volkswagen and Audi exhaust systems.

This part cross-references FEL-PRO 61458 for the same application. Walker 31729 is listed for 2006-2010 Volkswagen Jetta, 2006-2010 Volkswagen Passat, 2006-2010 Volkswagen GTI, 2006-2013 Audi A3, 2007-2014 Volkswagen Eos, 2009-2013 Volkswagen CC, 2009-2017 Volkswagen Tiguan, 2015-2016 Audi Q3, 2015-2016 Audi Q3 Quattro, and 2017-2018 Volkswagen Tiguan Limited.

What It Helps Fix

• Exhaust leaks at the flange connection
• Noise from a failing exhaust joint seal
• Soot or residue around the flange area
• Loss of sealing after exhaust service
• Fitment issues when replacing a worn OE-style gasket

Installation Notes and Tips

Confirm the flange pattern, bolt spacing, and port dimensions before installation. Clean both mating surfaces thoroughly so the gasket can seat evenly, and inspect the flange for warping, corrosion, or damage that could affect sealing. For best results, match the gasket to the vehicle’s exhaust configuration and verify the application against the part number 31729 before assembly.

Quality Assurance

Walker supplies exhaust sealing components designed to work with OE exhaust parts and Walker replacement systems. The use of high temperature graphite with a steel core supports consistent sealing performance in exhaust repair applications.
