The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant component for the ARUF060-00A-1A air handler. The flowrator (piston-style metering device) regulates refrigerant flow into the evaporator coil, and this inlet tube routes liquid refrigerant to the flowrator body. A kinked, corroded, or mismatched tube can restrict flow and cause poor cooling, coil icing, or improper subcooling.
Because this tube feeds the metering device, dimensional accuracy matters. The OEM B1796630 is pre-bent and sized to mate cleanly with the ARUF060 coil and flowrator seat. Generic tubing can introduce flare-fit problems or restrictions that degrade capacity. The factory part ensures correct geometry and a leak-tight connection.
Difficult — pro recommended. Working on the sealed refrigerant circuit requires EPA Section 608 certification, recovery of refrigerant, brazing or flare connections, evacuation, and recharge. This is not a DIY repair. Plan to have a licensed HVAC technician perform the swap.
