Bard 804-0579 - Equalizer Tube

Bard 804-0579 is an OEM equalizer tube used in the refrigerant circuit to provide the pressure reference needed for proper metering control at the evaporator outlet on Bard wall mounted air conditioners and heat pumps that use an externally equalized expansion device. A damaged, restricted, or leaking equalizer line can contribute to improper superheat and poor coil feeding, so replacing it with the correct Bard factory part helps restore stable system operation and protects the compressor from floodback or starving conditions. Confirm your unit model and the exact tubing connection style and routing before ordering, since equalizer tubes are application specific within Bard assemblies.
