Bard 904-0688BX - Reversing Valve Assembly

The Bard 904-0688BX reversing valve assembly (boxed) is an OEM refrigerant control component used in Bard heat pump systems to shift the flow of refrigerant so the unit can change between heating and cooling operation. When a reversing valve leaks internally, sticks, or fails to shift, it can cause poor heating or cooling performance and abnormal pressures, so replacing it with the correct Bard factory part helps restore proper mode changeover and dependable operation. Since refrigerant circuit repairs require recovery and recharging by a qualified technician, confirm this part number against your unit model and the Bard parts list before ordering to ensure proper fit and connection style.

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.
