Bard 5651-177BX - Thermal expansion valve
The Bard 5651-177BX is an OEM thermal expansion valve with 3/8 inch by 3/8 inch connections, designed to meter refrigerant into the evaporator and maintain stable superheat for proper cooling performance in compatible Bard wall mount and packaged systems. A properly functioning TXV helps prevent coil flooding or starvation, supports consistent suction conditions, and can improve reliability when addressing symptoms like poor cooling, erratic pressures, or icing that trace back to a metering device issue. Because fit and application vary by unit model and refrigerant, confirm compatibility by matching the part number in your Bard parts list or service manual before ordering.

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.
