The Goodman B1796630 is a genuine OEM flowrator inlet tube used in ATUF363616AA air handlers and related Goodman/Amana coil assemblies. The flowrator inlet tube routes refrigerant into the metering device (flowrator/piston) that feeds the evaporator coil. Though small, a damaged or kinked tube can disrupt refrigerant flow and cause poor cooling performance, so using the correct OEM part is essential during coil or metering-device service.

OEM vs. Generic
