Exhaust Pipe Flange Gasket for OE-Style Sealing

The Mahle F5451K exhaust pipe flange gasket is an OEM-standard sealing solution for exhaust manifold to exhaust pipe connections. Built with graphite and a 2.00-inch inside diameter, it helps maintain a tight seal where exhaust joints are exposed to heat and vibration.

Mahle gaskets are used by OEMs and technicians worldwide for dependable sealing performance. This F5451K gasket is a direct-fit style exhaust sealing component for select Ford, Mercury, Chrysler, and International Harvester applications, including classic Ford F-100, F-250, and F-350 trucks.

Key Features

  • Mahle F5451K exhaust pipe flange gasket
  • OEM Standard item grade for OE-style replacement
  • Graphite exhaust gasket material for sealing at high exhaust temperatures
  • 2.00-inch inside diameter
  • 2-bolt flange design
  • Contains exhaust pipe flange gasket
  • Cross-references FEL-PRO 9242 and 9269 for the same application

Detailed Description

The Mahle F5451K is an exhaust pipe flange gasket engineered for exhaust manifold to exhaust pipe sealing. Its graphite construction supports a secure seal at the flange joint, helping reduce exhaust leakage at a common wear point in older vehicles and restored drivetrains. This part number is a practical choice for service work on vehicles such as the Ford Mustang, Ford Thunderbird, and Mercury Cougar, as well as Ford F-100, F-250, and F-350 models listed in the fitment data.

Use Mahle F5451K when replacing a worn or heat-damaged exhaust flange gasket on applications that call for a 2.00-inch graphite gasket with a 2-bolt pattern. The part number F5451K is also referenced in interchange listings for Chrysler, Ford, International Harvester, and Rol applications.

What It Helps Address

  • Exhaust leaks at the manifold-to-pipe flange
  • Noise from a failing exhaust joint seal
  • Soot marks or odor from a leaking flange connection
  • Loss of sealing after heat cycling and age
  • Service replacement for deteriorated graphite gasket material

Installation Notes and Tips

Confirm the flange pattern, 2.00-inch inside diameter, and application notes before installation. Clean both mating surfaces thoroughly so the gasket seats evenly, and inspect the flange for warping, corrosion, or pitting that could affect sealing. For best results, follow the vehicle service manual torque sequence and recheck the joint after initial heat cycling.

Quality Assurance

Mahle supplies gaskets trusted by OEMs and technicians around the world, and this part is built to OEM-standard expectations for exhaust sealing service. The F5451K is backed by Mahle’s established gasket manufacturing experience for repair and replacement applications.
