• Expansion Valve 3/8" X 3/8"

Bard part number 5651-210 is an OEM expansion valve with 3/8 inch by 3/8 inch connections, used to meter refrigerant into the evaporator coil so the system maintains stable superheat and consistent cooling. When an expansion valve sticks, plugs, or loses charge, you can see symptoms like poor capacity, hunting pressures, or a coil that floods or starves, so replacing it with the correct Bard valve helps restore proper refrigerant control and protects the compressor under normal operating conditions. Because fit and calibration vary by model and refrigerant, confirm compatibility with your unit’s Bard parts list or service manual before ordering and replace the filter drier and evacuate properly anytime the sealed system is opened.
