Fixed Orifice Tube

WARNING: This page is about a different car, the 1995 Ford RV Cutaway, 1995 Ford Econoline, 1995 Ford Cutaway, and 1995 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.

Fixed orifice tube is a restriction between high and low pressure liquid refrigerant. Tube meters flow of liquid refrigerant into main system evaporator core. Vans use a Red, .062" (1.57 mm) orifice tube. Fixed orifice tube is located in refrigerant line near condenser. Filter screens are positioned on tube inlet and outlet ports. "O" rings on tube body prevent liquid refrigerant from by-passing fixed orifice tube. Fixed orifice tube can be removed from A/C line and serviced.
