OEM Ford IDI, 7.3, 6.0, & 6.4 Powerstroke A/C Orifice Tube | YG346 | 1990-2010 Ford IDI / Powerstroke 7.3L / 6.0L / 6.4L

The orifice tube is a metering device that creates a restriction to drop the pressure / temperature in the liquid line. It meters the flow of Freon/refrigerant only allowing enough liquid refrigerant through to easily flood the evaporator. Orifice tubes are defined by color, each color has a different size metering tube. When replacing the orifice tube always replace with the same color. Because of the screen and small metering tube, anytime you replace a compressor, the orifice tube also must be replaced. All Motorcraft parts carry a 2 year warranty.
