Bard part number 5201-022BX is an OEM A/C liquid line filter drier (P-Y), supplied boxed, that helps protect the sealed refrigeration circuit by trapping moisture, acids, and fine contaminants before they can damage critical components like the expansion device and compressor. Installed in the liquid line, this drier supports reliable operation after a repair, component replacement, or refrigerant-side service where the system has been opened. Use it when restoring a Bard wall-mounted air conditioner or heat pump to proper performance, and confirm the correct match by model and serial number to ensure the right capacity and connection style for your unit.
* Orders less than $50 may incure a minimum order fee.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
