Bard 804-0323 is an OEM equalizer tube used in the refrigerant circuit to transmit pressure to the system’s metering control so it can regulate refrigerant flow correctly under changing load and coil conditions. When an equalizer line is kinked, leaking, or damaged during service, performance can suffer with symptoms like unstable superheat, poor cooling, or coil icing, so replacing it with the correct Bard tube helps restore proper control response and reliable operation. This part is intended for direct-fit replacement on compatible Bard wall-mount equipment; confirm fit by matching the full unit model and serial number information to the correct Bard parts list before ordering.
