🛠️ HVAC Depot Pro Tip

For the 340620-720, match the complete factory part number before ordering:

Item #: 340620-720
MFR #: 340620-720
Component: TXV Replacement Kit

Do not choose a replacement TXV based only on its appearance or tubing size. The correct valve must match the equipment's refrigerant, capacity, evaporator coil, connection configuration, equalizer arrangement, and factory application.

Before installation, verify the complete equipment model and serial number against 340620-720.

Equipment / Model Compatibility

The Factory Authorized Parts 340620-720 should be used with compatible HVAC equipment specifically identified for this factory TXV kit.

Before ordering, verify:

  • Complete equipment model number
  • Serial number
  • Original TXV or kit number
  • Refrigerant type
  • System capacity
  • Indoor evaporator coil
  • TXV inlet and outlet connections
  • Equalizer configuration
  • Factory charging specifications

Because TXV specifications can vary substantially between otherwise similar equipment, 340620-720 should be matched by the factory part number whenever possible.
