The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant tubing component for the ARPF374316AA air handler and compatible Goodman/Amana evaporator coils. It feeds refrigerant into the flowrator (fixed-orifice metering device) at the coil inlet, ensuring the correct charge distribution across the coil circuits for proper cooling performance.

This small but critical tube is a common replacement during coil service, brazing repairs, or flowrator/piston changes. Using the correct OEM inlet tube guarantees the right diameter, length, and braze fit so the metering geometry stays within Goodman's specification.

OEM vs. Generic

Installation

Difficulty: Advanced — Professional Required. Replacing this tube involves opening the sealed refrigerant system, recovering refrigerant, brazing, evacuating, and recharging. This work must be performed by an EPA-certified HVAC technician.
