Bard 5651-219BX - 1/2 in Check Valve
Bard part number 5651-219BX is an OEM 1/2 inch check valve used in Bard wall mounted packaged HVAC equipment refrigerant piping to allow flow in the intended direction while helping prevent reverse flow that can contribute to performance issues during operation or off cycle conditions. This boxed replacement valve is sized 1/2 inch by 1/2 inch, making it a common service item when repairing or restoring proper refrigerant circuit behavior on compatible Bard units. For best results, confirm your unit model and serial number and match the connection size and flow direction before installation to ensure correct fit and function with Bard specifications.

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.
