The Goodman B1796630 is a genuine OEM flowrator inlet tube for the Goodman AEPF303616BA air handler and compatible Goodman/Amana fan-coil units. This precision tube connects the refrigerant line to the flowrator (piston-style metering device) at the evaporator coil, ensuring correct refrigerant entry and metering for proper cooling performance. Replacing a kinked, corroded, or damaged inlet tube restores designed flow and prevents capacity loss.
The genuine OEM B1796630 has the exact length, bend, and fitting size to mate with the Goodman flowrator and coil distributor without strain on the brazed joints. Generic tubing may require rework that risks leaks at the connections. On a sealed refrigerant system, OEM fit minimizes the chance of a comeback leak.
Advanced — this is a sealed-system repair requiring EPA-certified refrigerant recovery, brazing, evacuation, and recharge. It is not a DIY part; a licensed HVAC technician should perform the replacement. Bench time is short, but proper recovery and recharge are required by law.
