Global Parts 3411931 A/C Expansion Valve

Honda Civic, Insight, and Clarity A/C Expansion Valve

Global Parts 3411931 is an A/C expansion valve/orifice tube for select Honda applications. It meters refrigerant flow before the evaporator so the system can use refrigerant cooling capacity efficiently. This part number 3411931 is a direct-fit service component for 2016-2021 Honda Civic, 2017-2019 Honda Clarity, and 2019-2022 Honda Insight models.

Key Features

• Expansion valve/orifice tube design for refrigerant flow control at the evaporator
• Helps maintain proper pressure drop across the A/C system
• Fits 2016-2021 Honda Civic, N/A
• Fits 2017-2019 Honda Clarity, N/A
• Fits 2019-2022 Honda Insight, N/A
• Global Parts part number 3411931 for service and replacement matching

How It Works

The expansion valve reduces refrigerant flow before it enters the evaporator, allowing the refrigerant to absorb heat more effectively. On Honda Civic, Honda Clarity, and Honda Insight A/C service jobs, replacing a worn or restricted valve can restore proper refrigerant metering and help the system operate as intended. This part cross-references UAC EX529514C for the same application.

Common A/C Problems It Can Address

• Weak cabin cooling performance
• Improper refrigerant metering at the evaporator
• Erratic A/C outlet temperatures
• Restricted refrigerant flow from contamination or wear
• Service-related A/C performance loss after component replacement

Installation Notes

Replace the expansion valve/orifice tube during A/C system service, especially when the system has been opened for repair. Verify the vehicle application before installation and follow the correct evacuation, recharge, and leak-check procedures for the Honda Civic, Honda Clarity, or Honda Insight. Clean system practices matter because debris or moisture can affect valve performance.

Quality Assurance

Global Parts recommends changing the expansion valve/orifice tube each time the A/C system is serviced. This part is built for the listed Honda fitments and is intended for professional A/C repair workflows.
