The Goodman B1796630 Flowrator Inlet Tube is the genuine OEM refrigerant inlet tube that feeds the flowrator (piston-style metering device) on AEPT060-00C-1A air handler coils. This small but essential tube delivers liquid refrigerant to the metering orifice so the evaporator coil receives the correct flow for proper cooling and dehumidification. A bent, kinked, or corroded inlet tube can restrict flow and cause poor cooling, icing, or compressor strain.
Refrigerant tubing must match the exact diameter, length, and bend profile to seat correctly against the flowrator and distributor. The OEM B1796630 is formed to factory spec, ensuring a leak-free brazed joint and unrestricted refrigerant flow. Generic substitutes risk dimensional mismatch and leak points at the connection.
Advanced — Professional Only. Replacement requires recovering refrigerant, brazing the new tube, evacuating, and recharging the system per EPA Section 608. This is a licensed-technician job and is not a DIY repair.
