Goodman B1796630 Flowrator Inlet Tube

The B1796630 is a genuine OEM Goodman flowrator inlet tube used in the refrigerant metering circuit of the ADPF304216AC evaporator coil. The flowrator (piston-style metering device) inlet tube routes liquid refrigerant into the metering piston for proper distribution across the coil. A damaged, kinked, or corroded inlet tube can cause poor metering, low capacity, and uneven cooling.

Specifications

Type: flowrator inlet tube / liquid line stub
Material: copper
Function: feeds the refrigerant metering piston
Fit: OEM direct replacement for ADPF304216AC
OEM Part Number: B1796630
Brand: Goodman

OEM vs. Generic

The OEM inlet tube is bent and sized to match Goodman's coil geometry and piston seat exactly, ensuring a clean brazed joint and correct metering. Generic tubing requires custom fabrication and risks restriction or leaks at the joints. Genuine OEM is the reliable path here.

Installation Difficulty

Advanced. Replacement involves recovering refrigerant, brazing the tube into the metering assembly, evacuating, and recharging. This is EPA-certified technician work — improper brazing or charge will damage the system. Professional installation strongly recommended.
