The Goodman B1796630 Flowrator Inlet Tube is the genuine OEM refrigerant inlet line that connects the metering device (flowrator/piston) to the evaporator coil on Goodman ADPF30421BA air conditioner coil assemblies. This precision-formed copper tube carries liquid refrigerant into the coil distributor, and its exact bend geometry and braze fittings are critical for proper charge flow and leak-free operation.

OEM vs. Generic

This is a genuine Goodman OEM component, factory-matched to the coil's distributor and metering port. Unlike universal copper tubing that must be cut and bent on-site, the OEM tube arrives pre-formed to the correct length and angle — eliminating guesswork, reducing braze joints, and protecting your warranty. Generic tubing may save a few dollars but risks restriction, kinks, or leaks at improvised fittings.

Installation Difficulty

Advanced (HVAC technician required). Replacing the flowrator inlet tube requires recovering refrigerant, brazing under nitrogen purge, evacuating, and recharging the system. This is not a DIY repair and should be performed by an EPA 608-certified technician. Plan on 1–2 hours including recovery and re-charge.
