Bard 804-0451 - Equalizer Tube

Bard part number 804-0451 is an OEM equalizer tube used in Bard wall-mounted air conditioners and heat pumps to support proper refrigerant metering at the expansion device by balancing pressure feedback, which helps the system maintain stable superheat and protect overall cooling performance. If your unit is experiencing improper refrigerant control after a coil or metering device service, replacing the equalizer tube with the correct Bard OEM part helps ensure the tubing routing, flare or braze connections, and fit align with the original factory design. Because tubing and metering components are model and refrigerant specific, confirm compatibility by matching your unit model and serial number to the appropriate Bard parts list or service manual before ordering.
