The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant metering component for ARUF049-00A-1A air handlers. The flowrator (piston-style metering device) and its inlet tube regulate refrigerant flow into the evaporator coil, ensuring correct superheat and efficient cooling performance.
OEM tubing is sized to the exact diameter and length specified for the ARUF049 coil circuit, preserving the engineered refrigerant charge and metering rate. Generic or improvised tubing can introduce flow restrictions, brazing fit issues, or capacity loss. The OEM part drops in without modification.
Inlet tubes are replaced during coil service, flowrator changes, or when a tube is kinked, corroded, or damaged during prior repairs. Using the correct OEM tube restores factory metering behavior.
Installation Difficulty: Advanced — requires recovering refrigerant, brazing connections, evacuating, and recharging the system. This is a professional HVAC task; EPA Section 608 certification is required to handle refrigerant.
