The Goodman B1796630 is a genuine OEM flowrator inlet tube for ARUF018-00A-1 air handlers and compatible Goodman/Amana evaporator coils. The flowrator (piston-style metering device) inlet tube carries liquid refrigerant into the metering orifice that feeds the evaporator coil. A damaged, corroded, or restricted inlet tube can disrupt refrigerant flow, hurting cooling capacity and efficiency. This exact-fit tube restores proper refrigerant delivery during coil or metering-device service.

Specifications

Type: Flowrator inlet tube (refrigerant metering)
Function: Liquid refrigerant feed to the flowrator/piston
Fits: Goodman ARUF018-00A-1 air handler coil

OEM Part Number: B1796630

OEM vs. Generic

The OEM B1796630 matches the exact diameter, length, and fitting required to seat correctly against the flowrator body, ensuring a leak-free brazed connection. Because refrigerant components must hold pressure precisely, OEM is strongly recommended over generic tubing, which may not match the fitting geometry.

Installation Difficulty: Hard (Professional Required)

This is a sealed-system refrigerant part. Replacement requires EPA Section 608 certification, recovery of the refrigerant charge, brazing, evacuation, and recharging. This part must be installed by a licensed HVAC technician — do not attempt as a DIY repair.
