Exhaust Pipe Flange Gasket for OE-Style Sealing

AP Exhaust 8423 is an exhaust pipe flange gasket built for sealing the joint between exhaust components where flange connection integrity matters. With a 2-3/16 inch inside diameter and 11/16 inch thickness, it is sized for specific OE-style exhaust applications across a wide range of Nissan, Mitsubishi, Ford, Mazda, Mercury, Pontiac, Chevrolet, and Scion vehicles.

Use AP Exhaust 8423 when you need a direct-fit exhaust pipe flange gasket for service work on vehicles such as the Nissan Sentra, Nissan Juke, and Mitsubishi Galant. The part number 8423 is also used in multiple front, rear, left, right, and converter-to-muffler applications depending on the vehicle and exhaust layout.

Key Features

  • AP Exhaust part number 8423
  • Exhaust pipe flange gasket for sealing flange joints
  • Inside diameter: 2-3/16 inches
  • Thickness: 11/16 inch
  • Fits a broad range of OE exhaust applications, including Nissan Sentra, Nissan Juke, and Mitsubishi Galant
  • Application-specific fitment includes left, right, and converter-to-muffler positions where listed

Detailed Description

This AP Exhaust 8423 gasket is intended for exhaust flange sealing in applications that require the specified 2-3/16 inch inside diameter and 11/16 inch thickness. It is listed across many factory-style exhaust connections, including 2013-2019 Nissan Sentra Federal Emissions, 2013-2017 Nissan Sentra Calif. Emissions, 2011-2016 Nissan Juke, 2004-2012 Mitsubishi Galant, and 2008-2013 Mitsubishi Outlander converter to muffler service. The same part number 8423 also appears in fitments for 1995-2002 Chevrolet Camaro and Pontiac Firebird exhaust positions, making it a useful reference for buyers matching an OE-style flange gasket to the exact vehicle and exhaust location.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

  • Exhaust leaks at a flange connection
  • Noise from a worn or damaged gasket at the pipe joint
  • Soot or odor escaping from the exhaust seam
  • Loss of sealing after exhaust service or component replacement
  • Fitment issues when replacing an OE-style flange gasket on listed vehicles

Installation Notes and Tips

  • Verify the vehicle year, make, model, and exhaust position before ordering.
  • Match the gasket to the listed application notes, including Federal Emissions, Calif. Emissions, or OE pipe usage where specified.
  • Inspect flange surfaces for warping, corrosion, or debris before installation.
  • Confirm the gasket dimensions against the existing part when servicing a direct-fit exhaust joint.

Quality Assurance

AP Exhaust 8423 is a cataloged exhaust sealing component with defined dimensions and application-specific fitment data for direct vehicle matching. Use the listed vehicle coverage and position notes to confirm the correct exhaust pipe flange gasket for your repair.
