Mell 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.
How does AC orifice tube work?
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 are the different color orifice tubes?
Do Orifice Tube Colors Mean Anything? If you’ve ever seen an orifice tube, then you know that they’re all different colors, from maroon to dark gray or purple. While you may have a personal preference of a blue orifice tube going on your truck rather than a yellow or brown one, the colors do matter.
What color should my orifice tube be?
What is the purpose of AC orifice tube?
Where is the orfice tube or filter is located?
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.
Were is the orifice tube located?
Orifice tubes are always located in the refrigerant tubing that connects to the high pressure port on the evaporator. However, the tube may be located in the evaporator tubing itself. In either designed, you must evacuate the system and disconnect the high pressure line from the evaporator to replace the orifice tube.
Where is a/C orifice tube located?
With Front and Rear A/C, the Expansion Block/Orifice Tube is located in a Y-shaped junction block in the tube between the condenser and the front evaporator. The junction block is located near the right side of the radiator support.
Where is the AC orifiice tube located?
Auto AC orifice tube locations. Because of the way an orifice tube works, it’s usually located on the inlet to the evaporator coil . However, on some vehicles the orifice tube location varies. Sometimes it is built into the liquid or high pressure line or inserted into the high pressure line right where the line connects to the condenser.
