The Goodman B1796630 is a genuine OEM flowrator inlet tube for the ADPF304216BA evaporator coil. This precision refrigerant-metering component carries liquid refrigerant to the flowrator (piston) at the coil inlet, ensuring the correct flow rate for proper superheat, full cooling capacity, and efficient operation. Replacing a kinked, corroded, or leaking inlet tube restores design performance and prevents refrigerant loss.

Specifications

Type: Flowrator / metering device inlet tube
Function: Routes liquid refrigerant to the coil flowrator piston
Material: Copper refrigerant tubing
Fits: Goodman ADPF304216BA evaporator coil
Part Number: B1796630

OEM vs. Generic

The genuine Goodman tube is sized to the exact length, bend radius, and fitting type the coil requires, so it brazes in cleanly and meters refrigerant as engineered. Aftermarket substitutes with the wrong inside diameter or geometry can throttle flow, cause flooding or starving of the coil, and degrade efficiency. OEM keeps the metering circuit matched to the system.

Install Difficulty

Advanced / Professional — this is a sealed-system repair requiring EPA-certified refrigerant recovery, brazing, evacuation, and recharge. Should be installed by a licensed HVAC technician; improper brazing or charge can damage the compressor.
