The Goodman B1796630 Flowrator Inlet Tube is the genuine OEM refrigerant tube that feeds the flowrator (piston-style metering device) on ARPF374316BA air handlers and compatible Goodman/Amana coils. This small but critical component carries liquid refrigerant into the metering orifice; a damaged, kinked, or leaking inlet tube throws off the refrigerant charge and can starve the coil, hurting cooling capacity and efficiency.

Replacing it with the correct factory tube restores proper metering geometry and a clean brazed connection.

Part number: B1796630
Function: Liquid refrigerant inlet to flowrator metering device
Material: Copper refrigerant tubing
Fits: Goodman ARPF374316BA and compatible models
Category: Tubing / metering components

OEM vs. Generic

Refrigerant tubing must match the original bend radius, length, and inside diameter to mate with the flowrator and distributor correctly. This OEM tube guarantees that fit. Generic copper substitutes often require rework and risk introducing restrictions or leaks at the joints.

Installation Difficulty

Advanced. This part requires recovering the refrigerant, brazing the new tube in place, evacuating, and recharging the system. It should be installed by an EPA-certified HVAC technician — not a DIY job.
