Global Parts 3411884 A/C Orifice Tube

Restore proper refrigerant control in the A/C system with this Global Parts A/C orifice tube. Part number 3411884 slows refrigerant flow before the evaporator so the system can use cooling capacity more effectively. It is a direct-fit service part for a wide range of GM trucks and SUVs, including Chevrolet Silverado, GMC Sierra, Cadillac Escalade, and Tahoe applications.

Key Features

• A/C orifice tube for refrigerant flow restriction before the evaporator
• Helps maintain correct expansion and cooling performance in the HVAC system
• Fits front A/C applications on select GM vehicles
• Dark grey PPOT configuration noted for listed applications
• Cross-references Four Seasons 38644 for the same application

Detailed Description

The Global Parts 3411884 orifice tube is used in the air conditioning circuit to meter refrigerant as it enters the evaporator. By controlling flow at this point, the system can deliver more consistent cooling performance. This part number 3411884 is listed for many 2006-2014 Chevrolet, GMC, Cadillac, and Hummer models, including front A/C service on vehicles such as the Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade.

Compatible With 2007-2014 Cadillac Escalade, front; 2008-2014 Chevrolet Tahoe, front; and 2007-2014 GMC Yukon, front. It also covers additional Silverado, Sierra, Suburban, Avalanche, Yukon XL, and H2 applications shown in the fitment data.

What It Helps Address

• Weak or uneven cabin cooling
• Restricted refrigerant metering in the A/C circuit
• Service replacement during evaporator or compressor work
• Loss of cooling efficiency after contamination in the system
• Need for a correct-fit HVAC flow restrictor on GM platforms

Installation Notes and Tips

Install in the correct A/C line location for the listed vehicle application and verify the front HVAC configuration before service. When replacing an orifice tube, inspect the system for debris, contamination, and signs of compressor wear so the new part is not exposed to the same condition. Global Parts recommends replacing the expansion valve or orifice tube each time the A/C system is serviced.

Quality Assurance

Global Parts supplies this HVAC service component as a direct replacement for listed GM applications. The part is engineered for the refrigerant metering function required by the system and is backed by the brand’s product standards for fit and function.
