Bard part number 800-0037 is an OEM cap tube assembly used as a fixed metering device in the refrigeration circuit of select Bard wall mount and other packaged HVAC units. The capillary tube is sized to help control refrigerant feed to the evaporator, so when a system has symptoms like improper superheat, weak cooling, or a known restriction from contamination, replacing the correct factory cap tube assembly can be critical for restoring stable pressures and performance. Because cap tubes are application specific by unit model and refrigerant design, confirm 800-0037 against your Bard model and serial before ordering to ensure proper fit and correct system operation.
