The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant tubing component for Goodman AEPF18301BA air handlers. The flowrator (piston-style metering device) and its inlet tube feed liquid refrigerant into the evaporator coil at the correct rate. A damaged, kinked, or mismatched inlet tube can starve or flood the coil, hurting capacity and efficiency, so the factory-correct tube matters for proper metering.

Specifications

OEM Part Number: B1796630
Type: Flowrator inlet tube (refrigerant metering line)
Primary Fit: AEPF18301BA
Brand: Goodman (OEM)
Function: Routes liquid refrigerant to the flowrator/coil inlet

OEM vs. Generic

The OEM B1796630 arrives with the correct length, bend, and fitting diameter to braze cleanly into the existing line set and seat against the flowrator. Generic tubing often needs rework that introduces leak points or alters the metering geometry. For a sealed refrigerant circuit, the exact OEM tube protects system charge accuracy and reliability.

Installation Difficulty

Advanced (4/5). Involves opening the sealed refrigerant circuit — recover refrigerant, braze the connection, pull a vacuum, and recharge. This is EPA-regulated work and must be performed by a certified HVAC technician with proper recovery equipment.
