Fixed Orifice Tube
WARNING: This page is about a different car, the 2001 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
The fixed orifice tube for this system is color coded Green and has an orifice diameter of 0.052" (1.25 mm). Located in condenser to evaporator line, orifice tube changes high-pressure liquid refrigerant into a low-pressure liquid. Orifice tube has filter screens on inlet and outlet ends of orifice body to filter any debris in system. "O" rings on orifice tube prevent high-pressure liquid from by-passing orifice tube. Orifice tube is not serviceable and must be replaced. A new orifice tube should be installed whenever a new compressor is installed.
