The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant metering line designed for Goodman/Amana ARUF018-00A-1A air handlers. The flowrator (piston-style metering device) inlet tube delivers liquid refrigerant to the evaporator coil at the correct flow rate, ensuring proper superheat, efficient heat transfer, and reliable cooling performance. A worn, kinked, or corroded inlet tube can cause flooding, starving, or refrigerant leaks at the coil.

OEM vs. Generic

This genuine OEM tube is pre-formed to the exact length, bend radius, and fitting size required by the ARUF018 coil assembly. Generic copper line must be hand-bent and brazed to fit, increasing the risk of leaks and incorrect refrigerant flow. The factory part installs cleanly and maintains rated capacity.

Installation Difficulty

Advanced / Professional. Replacing a refrigerant-side component requires recovering the system charge, brazing the connection, pulling a vacuum, and recharging — EPA Section 608 certification is required. This is not a DIY job; schedule a licensed HVAC technician.
