⚙️ Key Features

  • Exhaust-system flange
  • Precision sealing and clamp surface
  • Designed for high exhaust temperature
  • Used with silencer 21134828
  • Correct mounting geometry for the associated V-clamp
  • Quantity varies by assembly, most commonly one

🔌 Function

The flange joins the silencer or exhaust pipe to the adjoining exhaust component while maintaining a gas-tight joint.

⚠️ Common Signs of Failure

  • Soot around the joint
  • Warped or cracked flange
  • Exhaust leakage or increased noise
  • Loose V-clamp connection

🛠️ Service Notes

  • Clean both mating faces back to clean metal and check them for flatness and for burrs or old gasket left in the sealing area; a face pulled up around a stud hole will not seal however hard it is tightened
  • Always fit a new gasket, seal or O-ring where the joint uses one, and only use a jointing compound if the workshop manual for your engine calls for one at that joint
  • Draw the fasteners up evenly in stages, working across the flange rather than round it, and finish to the tightening sequence and figures given for your engine
  • Inspect studs, nuts and threads while the joint is apart and renew anything corroded, stretched or seized — exhaust-side fasteners rarely come out twice
  • Re-check the joint for leaks once the engine has been up to working temperature and cooled again
