Bard part 5811-007 is an OEM capillary tube used as a fixed metering device in select Bard wall mounted air conditioners and related packaged units to control refrigerant flow into the evaporator for stable cooling performance. This factory specified tube is sized at 0.064 inch ID by 0.125 inch OD and 18-1/2 inches long, so matching the part number is critical because even small sizing changes can affect capacity, pressures, and reliability. If you are diagnosing improper superheat, icing, or a restriction, confirm the correct application by unit model and serial number, and have the refrigerant circuit serviced by a qualified technician to ensure proper brazing, evacuation, and charging after replacement.
* Orders less than $50 may incure a minimum order fee.
