The Goodman B1796630 Flowrator Inlet Tube is a genuine OEM refrigerant-metering component for the Goodman ASPF303616BA air handler. This small but critical tube routes refrigerant into the flowrator (piston) metering device that feeds the evaporator coil. A damaged, kinked, or contaminated inlet tube can disrupt the refrigerant charge and reduce cooling capacity.
OEM tubing arrives pre-formed to the correct length, bend radius, and fitting diameter for the ASPF303616BA, ensuring a clean brazed joint and proper refrigerant flow. Generic copper stock requires cutting and bending and risks incorrect sizing that restricts flow or causes leaks at the connection.
Rating: Advanced. Replacement involves recovering the refrigerant, brazing the tube into the line set, pulling a vacuum, and recharging the system. This is EPA Section 608 certified work — a licensed HVAC technician is required. Do not attempt without proper recovery and evacuation equipment.
Power down and recover refrigerant before service. Confirm your unit is an ASPF303616BA prior to ordering.
