Bard 800-0421BX - Refrigerant Distributor Assembly

The Bard 800-0421BX Distributor Assembly is an OEM refrigerant metering and distribution component used in Bard wall-mount air conditioners and heat pumps to route incoming refrigerant into multiple evaporator coil circuits for proper coil feed and stable system operation. When a distributor is restricted, damaged, or leaking, you can see uneven coil temperatures, reduced capacity, and ongoing performance complaints, so replacing it with the correct Bard factory part helps restore balanced refrigerant flow and reliable cooling. Because this is a boxed distributor assembly, it is typically supplied as a ready-to-install refrigerant distribution package, but you should still confirm the exact unit model and serial number match 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.
