The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant metering component engineered for the Goodman ASPF303616AA air handler. This inlet tube routes liquid refrigerant into the flowrator (piston) metering device at the evaporator coil, ensuring the correct flow rate for proper superheat and reliable cooling performance. A cracked, kinked, or corroded inlet tube can cause refrigerant leaks, poor cooling, and compressor strain — replacing it with the exact OEM part restores factory performance.

OEM vs. Generic

This is a genuine Goodman OEM tube built to factory tolerances for a guaranteed leak-free braze fit. Generic or universal tubing often requires re-bending and cutting, raising the risk of restriction or leaks. For sealed-system refrigerant work, OEM fit is strongly recommended.

Installation Difficulty

Advanced — requires EPA 608 certification. Replacement involves recovering refrigerant, brazing the new tube, pulling a vacuum, and recharging. This should be performed by a licensed HVAC technician.
