Global Parts 3411891 A/C Expansion Valve

Global Parts 3411891 A/C Expansion Valve

Global Parts 3411891 is an A/C expansion valve for the refrigerant flow control side of the HVAC system. It slows refrigerant before the evaporator so the system can use cooling capacity efficiently. This part fits 1987-1989 Jeep Wrangler with factory A/C.

Key Features

• Right angle valve design for A/C flow restriction service
• Flare fitting connection style
• 30 cap tube configuration
• Direct fit for 1987-1989 Jeep Wrangler, factory A/C
• Part number 3411891 for catalog and cross-reference use

Product Details

This expansion valve is built for HVAC systems that use an orifice-style refrigerant metering component at the evaporator inlet. By reducing refrigerant pressure and regulating flow, it helps the evaporator absorb heat more effectively. Global Parts 3411891 is a fitment-based replacement for Jeep Wrangler models from 1987 through 1989 equipped with factory air conditioning. This part number 3411891 is also referenced in aftermarket catalogs for the same application.

This part cross-references UAC EX6004C for the same application.

Common Issues It Can Address

• Weak cabin cooling from improper refrigerant metering
• Uneven evaporator performance in the A/C system
• Restriction-related refrigerant flow problems
• Service-related replacement of a worn expansion valve

Installation Notes

Install during A/C service when the system is opened for repair or component replacement. Verify the valve style, flare fitting connection, and 30 cap tube configuration before installation. Clean the system thoroughly and confirm proper refrigerant charge after service. For Jeep Wrangler factory A/C applications, match the vehicle year and HVAC layout to the listed fitment before ordering.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced. That guidance supports consistent refrigerant control and helps maintain evaporator performance over time.
