How to remove and install an A/C orifice tube in an air conditioning system on GMC Sierra?

To remove the A/C orifice tube from an air conditioning system, the system must first be discharged. The tube is located in the liquid (high-pressure) line near the accumulator and can be removed by holding the stationary fitting with one wrench and loosening the other fitting with another wrench. The tube has a fixed-diameter orifice and a mesh filter at each end, and can be removed with needle-nose pliers. If it is stuck or breaks off, a special tool may be required. The orifice tube meters the refrigerant, changing it from a high-pressure liquid to a low-pressure gas, and can be reused if the screens aren't plugged, torn, or the plastic housing is intact and the brass orifice is unrestricted. To install the A/C orifice tube, insert it with the shorter end pointing toward the evaporator, reconnect the refrigerant line, and have the system evacuated, recharged, and leak-tested.

GMC Sierra A/C Orifice Tube

GMC Sierra A/C Orifice Tube manages refrigerant flow by creating a fixed pressure drop that lets liquid expand into cool vapor inside the evaporator. Unlike an adjustable expansion valve, this A/C Orifice Tube has no moving parts, it simply meters flow through its calibrated bore, causing the compressor to cycle on or off to keep cabin temperatures steady while separating high discharge pressure from the low suction side. Earlier and later truck years use the same basic straight plastic screen wrapped style, although some generations received a short length variant with a color coded tip to signify slightly different bore size for specific system pressures, both versions perform identically, yet the shorter tube installs closer to the condenser junction. Over time dirt, metal flakes and oil sludge can clog the A/C Orifice Tube screens, raising pressure, freezing the evaporator or leaving you with weak cooling at idle then warmer air while cruising. Regular service intervals advised by GMC keep the tube clean, and many Sierra owners can swap it themselves because the A/C Orifice Tube sits in an accessible liquid line. Using the correct color tube specified for your GMC pickup ensures every Sierra system receives the precise A/C Orifice Tube.

Each OEM GMC Sierra A/C Orifice Tube we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
