How to remove the A/C Orifice Tube on Chevrolet Corvette?

To remove the air conditioning system, start by discharging it and disconnecting the cable from the negative battery terminal. Then, open the hood and locate the evaporator line connection on the passenger's side of the engine compartment. Remove the mounting bolt and separate the lines, replacing the O-ring with a new one. The A/C orifice tube, which has a fixed-diameter orifice and mesh filters at each end, can be found inside the line leading to the evaporator. Use needle-nose pliers to remove it. The orifice tube is responsible for metering the refrigerant and changing it from a high-pressure liquid to a low-pressure gas. It can be reused if the screens are not plugged, torn, or the plastic housing over the screen is intact, and the brass orifice inside the housing is unrestricted. For installation, insert the orifice tube with the shorter end in first, towards the evaporator, and always replace the O-ring with a new one. Finally, have the system evacuated, recharged, and leak tested.

Chevrolet Corvette A/C Orifice Tube

The flow of refrigerant in the air conditioning circuit is controlled by the Chevrolet Corvette A/C Orifice Tube, which helps provide continuous cooling of the cabin. The A/C Orifice Tube serves as a metering gate and an inline filter by forcing liquid refrigerant through a narrow mesh screen and dropping its pressure. It captures dirt that could ruin metal sliding seals. Chevrolet sports models ensure comfort for all passengers when stopped at traffic lights or zooming down the highway because the A/C Orifice Tube allows compressor pressure to rise or fall until the right amount of cold mist reaches the evaporator. The opening never changes size. The earlier Corvette systems sometimes had a temperature sensing expansion valve that modified its opening via a series of tiny internal components. Most later cars, however, use the A/C Orifice Tube, which is a fixed valve that offers less fine tuning. The A/C Orifice Tube of any modern-day Corvette must be inspected to stop vent temperature fluctuations, erratic gauge readings, or iced over evaporator, and of course, timely replacement protects the complete Chevrolet climate loop.

Each OEM Chevrolet Corvette 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.
