The B1796630 is a genuine Goodman flowrator inlet tube engineered for ARUF061-00A-1A air handlers. This copper metering tube routes liquid refrigerant into the flowrator (fixed-orifice metering device) at the evaporator coil, ensuring correct refrigerant distribution and proper system charge. Using the exact OEM tube preserves the factory bend radius and braze fittings so your coil performs to specification.
This is a genuine Goodman OEM component, machined and bent to the exact factory geometry. Generic substitutes often require field re-bending and can introduce kinks or restrictions that starve the coil and trigger high-superheat faults. The OEM tube installs cleanly with no guesswork.
Advanced — requires recovering refrigerant, brazing with nitrogen purge, pressure testing, evacuation, and recharging. Recommended for EPA-certified HVAC technicians only.
