Bard 5651-156BX - Expansion Valve 3/8 x 3/8

Bard part number 5651-156BX is an OEM expansion valve with 3/8 inch by 3/8 inch connections, used to meter refrigerant into the evaporator coil so your Bard wall mount system maintains stable superheat, capacity, and overall cooling performance. A worn or restricted expansion valve can contribute to poor cooling, coil freeze ups, and erratic pressures, so replacing it with the correct Bard factory part helps restore proper refrigerant control and protects the compressor. Because expansion valves are application specific, confirm the part number against your unit model and serial tag and follow standard refrigeration practices for evacuation, dehydration, and leak testing during installation.

What does the "BX" suffix mean?

Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.

A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.

Example: 8406-142BX is physically identical to 8406-142.
