Mahle Exhaust Pipe Flange Gasket F5421K

The Mahle F5421K is an exhaust pipe flange gasket for sealing the joint between the exhaust pipe and converter or resonator connection. It is built for direct-fit applications on select Lincoln, Ford, and Mercury vehicles, including classic 1960s models that require a 2.00-inch inside diameter flange-style graphite gasket.

Key Features

  • Exhaust pipe flange gasket for sealing exhaust joints
  • Graphite sealing material for flange-type connections
  • 2.00-inch inside diameter specification
  • Direct fit for select 1963-1969 Lincoln Continental applications
  • Also fits 1965 Ford LTD, 1965 Ford Mustang, and 1965 Mercury Villager applications
  • Mahle sealing product line trusted by OEMs and technicians

Application Details

Compatible With 1963-1969 Lincoln Continental, pipe to converter; 1965 Ford LTD, resonator inlet; 1965 Ford Mustang, resonator inlet; and 1965 Mercury Villager, resonator inlet. The F5421K is also cross-referenced to FEL-PRO 9827 for the same application. If you are replacing a leaking exhaust flange gasket on a Lincoln Continental, Ford Mustang, or Ford LTD, this part number provides the correct sealing profile for the listed exhaust connection points.

Common Uses

  • Seals exhaust leaks at the flange connection
  • Restores a tight joint between pipe and converter
  • Addresses exhaust noise from a worn gasket
  • Helps correct soot marks around the exhaust flange
  • Supports repair of a damaged or flattened sealing surface

Installation Notes

Verify the flange type and 2.00-inch inside diameter before installation. Clean both mating surfaces thoroughly so the graphite gasket can seat evenly, and confirm the exhaust components align without forcing the joint. For best results, match the application to the exact vehicle and exhaust connection listed for F5421K.

Quality Assurance

Mahle gaskets are used in OEM and professional repair environments and are built to meet the sealing demands of exhaust system service. The F5421K is engineered as a direct replacement for the specified applications and is backed by Mahle’s manufacturing standards.
