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.

Can a bad or failing orifice tube cause a car to freeze?
If the AC evaporator or orifice tube malfunctions, it can cause refrigerant to flow unmetered through the vehicle’s AC system. This can cause the evaporator to freeze over, or frost to form or come from the vehicle’s AC vents.
What does the orifice tube in an expansion valve do?
The expansion valve, also known as an orifice tube in some designs, regulates the pressure of refrigerant that enters the evaporator. The tube is also where liquid refrigerant under pressure converts to a gaseous form.

What causes an orifice tube to become clogged?
The small diameter of the passage, while critical for the cooling system, makes an orifice tube susceptible to becoming clogged from debris within the system. An orifice tube becoming stopped up is just about the only way that it can ever fail, as it is a relatively simple component by design.
What should the Arrow be on the orifice tube?
The orifice tube should have an arrow that correlates to the flow of the refrigerant. Make sure you’re installing the orifice tube the right way. Getting the o-rings on the orifice tube slightly wet with oil helps with the installation. Loading…
Why do you need an orifice for r-134?
The orifice tube allows for a higher flow of R-134 refrigerant during times when more cooling is needed, and a smaller flow of refrigerant when less cooling is needed.
Do you need to replace the orifice tube in a compressor?
If it was full of metal shavings you have bigger fish to fry. Your compressor is going. You not only need to replace the orifice tube, but the compressor, condenser, accumulator and flush all the lines.
