Where is the AC orifice tube location?
A fixed orifice tube contains a small brass tube encased in a plastic case with a filter at each end to protect it from any debris in the system. It’s located on the high side between the condenser and the evaporator core.
Is the orifice tube on the high or low side?
An orifice tube is used to control the flow of refrigerant into the evaporator. It works in conjunction with compressor controls to maintain low side pressure at a sufficient level, to prevent evaporator icing or flooding. The orifice tube is placed in the high side liquid refrigerant line, at or near the evaporator.
Can a vehicle have an expansion valve and orifice tube?
The expansion valve does contain moving parts, including a self-contained meter system to regulate the refrigerant flow from the compressor to the evaporator. Most modern vehicles use either an orifice tube or an expansion valve depending on your make and model.
Do you need an orifice tube?
The orifice tube controls the amount of refrigerant entering the evaporator, and its diameter matches those of the evaporator system for smooth engagement without leaks. As the orifice tube contains no moving parts, vehicles that use these parts also need to employ an additional method of controlling refrigerant flow.
What color should my orifice tube be?
It always has to be orange to correspond with the truck’s orifice diameter.
Where is the orifice tube in an AC system?
It is usually installed at the evaporator inlet and works together with the orifice tube to regulate the flow of refrigerant through the vehicle’s AC system. Too much refrigerant flow and the evaporator core will freeze over; too little and the evaporator core will overheat and compromise the efficiency of the AC system.
How do you replace the orifice tube in a car?
Replacing the orifice tube requires you to completely evacuate the AC system and disconnect the high pressure liquid line. It’s not a fun job. • Replacement orifice of the exact same color and part number as the old unit Buy or rent a refrigerant recovery machine. Attach the manifold gauge set to the high and low side ports on your car’s AC system
