A desiccant which has absorbed a lot of moisture can cause the orifice tube to freeze, preventing the refrigerant from flowing further in the AC system. This can result in the corrosion of the system. What causes the orifice tube in an AC system to freeze? Insert the new orifice tube into the evaporator or LLOT or SLOT. Lubricate the O-rings on the new orifice tube with AC oil. Note the orientation of the orifice tube. Remove the orifice tube using needle nose pliers or removal tool. How do you remove the orifice tube in an evaporator? Generally, the orifice tube is placed between the condenser and evaporator as shown in the picture below: AC accumulator orifice tube systems are found in some automobiles while other vehicles include an expansion valve in place of the orifice tube and a receiver-drier instead of the accumulator.

An orifice is a small opening or hole in a plate or pipe or body. The valve helps control the flow of refrigerant through the evaporator, which is the main cooling component of the system.Īn orifice valve is a flow control valve that is used to restrict or control the fluid flow. Is orifice tube expansion valve?Īn orifice tube is similar to an expansion valve, with both performing an important function in a vehicle’s A/C system. It has 1 side that is a little smaller than the other, to supply more pressure. This tube is also known as the expansion tube, and is located within the tube between the condenser and the evaporator. One of the many parts that can fail within your vehicle’s air conditioning, is the orifice tube. 5 What causes the orifice tube in an AC system to freeze?.4 Where is the orifice tube in an AC accumulator system?.3 Where is the orifice tube located on an auto?.1 Where is the AC orifice tube location?. ![]()
