Goodman B1796630 Flowrator Inlet Tube

The Goodman B1796630 is a genuine OEM flowrator inlet tube for the ARUF042-00A-1B air handler evaporator coil. The flowrator (piston-style metering device) regulates refrigerant flow into the indoor coil, and this inlet tube carries liquid refrigerant from the line set to the metering orifice. A correct, leak-free inlet tube is essential for proper superheat, capacity, and efficiency. Damaged or kinked tubing causes poor cooling, frosting, and refrigerant loss.

Specifications

OEM Part Number: B1796630
Brand: Goodman (fits Amana equivalents)
Component: Flowrator / metering device inlet tube
Fits: ARUF042-00A-1B series air handler coils
Function: Delivers liquid refrigerant to the metering orifice

OEM vs. Generic

The genuine Goodman OEM tube matches the precise diameter, length, and braze fittings of the ARUF042 coil assembly. Generic tubing can introduce restriction or improper orifice seating, throwing off the refrigerant charge. For sealed-system components, OEM is the safe choice.
