The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM component for the refrigerant metering assembly on ARUF061-00A-1 air handler coils. The flowrator (piston-style metering device) inlet tube carries liquid refrigerant into the metering orifice, and a correctly sized, leak-free tube is essential for proper coil feed and rated cooling performance.
Refrigerant-side tubing must match exact diameter, length, and fitting type to braze and seal correctly. A generic substitute risks leaks and improper refrigerant feed. The genuine OEM B1796630 guarantees a precise fit to the factory flowrator assembly and a clean, reliable joint.
Difficulty: Advanced (4/5) — EPA-certified technician required. Replacement involves recovering refrigerant, brazing connections, pulling a vacuum, and recharging the system. This is not a DIY part. Always have a licensed HVAC professional perform refrigerant-circuit work.
