Bard 5220-012 - Discharge muffler/check valve

Bard part 5220-012 is an OEM discharge muffler and check valve assembly used in the compressor discharge circuit on select Bard wall-mount air conditioners and heat pumps. It helps smooth discharge gas pulsation to reduce vibration and noise while also providing one-way flow protection to support proper refrigerant management during operation and off cycles. Replacing a worn or restricted muffler/check valve can help address rattling, excessive compressor sound, or discharge-side performance issues, but correct fit depends on the exact unit model and serial range, so match this part number to your Bard parts list before ordering.
