The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant metering component for ATUF182416AA air handlers. The flowrator (piston-style metering device) inlet tube delivers liquid refrigerant to the evaporator coil at the correct rate, ensuring proper superheat and full coil performance. A damaged, kinked, or contaminated inlet tube causes poor cooling, frosting, and inefficient operation.

OEM vs. Generic

This genuine OEM tube is sized to factory bore and length so refrigerant metering matches system design. Generic substitutes with incorrect orifice or tube dimensions throw off superheat and reduce capacity. OEM ensures correct charge balance and rated efficiency.

Installation Difficulty: Hard

Rated Hard — this is a sealed-system repair. Recover refrigerant, braze in the new inlet tube, pull a deep vacuum, and recharge to spec. EPA Section 608 certification and proper recovery equipment are required. Professional HVAC service is strongly recommended; budget 1–2 hours.
