Detailed Product Description

The Global Parts 3411263 expansion valve is built for older A/C systems that use flare-style connections and capillary/equalizer tube routing. By metering refrigerant before it reaches the evaporator, it helps maintain the pressure drop needed for effective cabin cooling. It is a direct-fit service part for many classic import and domestic vehicles, including 1978-1984 Jeep Cherokee, 1981-1985 Mercedes-Benz 380SL, 1978-1982 BMW 320i, and 1978-1983 Porsche 911.

Compatible With 1961-1991 Chrysler 300, Imperial, Newport, and New Yorker; 1974-1984 Jeep Cherokee, J10, J20, and Grand Wagoneer; 1977-1984 BMW 320i, 528i, 528e, and 530i; 1978-1989 Mercedes-Benz 300SD, 380SE, 380SEL, 380SLC, 380SL, and 560SL; 1978-1983 Porsche 911; 1979-1981 Mazda 626 and RX-7; and 1991 Volkswagen Cabriolet.

What It Helps Address

• Weak or uneven A/C cooling at the evaporator
• Incorrect refrigerant metering in flare-fitting systems
• Service replacement for a worn or restricted expansion valve
• Cooling performance issues after A/C system repair
• Fitment needs for classic BMW, Mercedes-Benz, Jeep, Porsche, Mazda, Chrysler, and Volkswagen HVAC systems

Installation Notes and Tips

Verify the vehicle uses 1/4 flare fittings and the listed capillary and equalizer tube lengths before installation. Replace the expansion valve during A/C service when the system has been opened, and confirm the refrigerant charge, compressor operation, and evaporator condition after installation. For fitment-specific service, match the vehicle application exactly to the listed year and model.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. Part number 3411263 is engineered as a service replacement for the listed applications and cross-references multiple aftermarket numbers for the same use.
