The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM component for the AEPF303616CA air handler. The flowrator (piston-style metering device) regulates the flow of liquid refrigerant entering the evaporator coil, and this inlet tube provides the precise connection point that feeds it. Correct metering is essential for proper superheat, full cooling capacity, and protecting the compressor from liquid flood-back. A damaged, kinked, or leaking inlet tube can cause poor cooling, icing, and efficiency loss.
This genuine Goodman tube matches the exact diameter, length, and flare geometry required by the AEPF303616CA coil circuit. Generic tubing often differs in bore size or fitting type, risking improper metering, leaks at the braze joint, or refrigerant restriction. The OEM part guarantees a leak-free, factory-spec connection.
Advanced. Replacement involves recovering refrigerant, brazing, evacuating, and recharging the system — work that requires EPA Section 608 certification and proper tools. This part should be installed by a licensed HVAC professional. Confirm your model number before ordering.
