The Red Dot 71R8506 Orifice Tube is a brown Ford-style CCOT fixed orifice tube designed for cycling clutch air conditioning systems. It meters refrigerant flow into the evaporator to maintain proper cooling balance and compressor protection.
This model features a .047 in. orifice size, making it a smaller metering option compared to blue, red, or orange Ford tubes. The brown color allows quick visual identification during service.
The 71R8506 is used in Ford applications and cross-references to John Deere, Mack, and Volvo systems.
Always confirm orifice size and OE number before installation.
