The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant tube that feeds the flowrator (piston-style) metering device on the AEPF30361BA air handler coil. It delivers liquid refrigerant to the metering orifice at the correct geometry, supporting proper coil feed and system charge balance.
A kinked, corroded, or improperly sized inlet tube can restrict flow, cause uneven coil feeding, and degrade cooling capacity. The OEM tube restores the factory-specified inner diameter and fitting alignment for correct metering performance.
The OEM B1796630 is formed to the exact length, bend, and flare specification of the AEPF30361BA coil assembly, so it mates cleanly with the flowrator body and liquid line. Generic tubing must be cut and bent on site, risking restriction and leak-prone joints. For a sealed refrigerant circuit, the OEM tube is the correct choice.
Advanced — this is a sealed-system repair. The system must be recovered, the connection brazed or fitted per spec, then evacuated and recharged. Refrigerant work should be performed by an EPA 608-certified technician. Plan 45+ minutes plus recovery/recharge time.
