Global Parts 3411895 A/C Expansion Valve

Global Parts A/C Expansion Valve 3411895

Global Parts 3411895 is an A/C expansion valve/orifice tube for vehicles that use screw-on fittings. It regulates refrigerant flow before the evaporator so the system can use refrigerant cooling capacity efficiently. This part is a direct-fit service item for select Acura and Lexus applications, including Acura RL and Lexus SC300, SC400, GS300, and LS400.

Key Features

• Expansion valve/orifice tube for HVAC A/C flow control
• Helps meter refrigerant before the evaporator
• Designed for screw-on fitting applications
• Fits 1996-2004 Acura RL, screw on fittings
• Fits 1994-2000 Lexus SC300 and SC400, screw on fittings
• Fits 1993-1997 Lexus GS300 and 1993-1994 Lexus LS400, screw on fittings

Detailed Description

The Global Parts 3411895 expansion valve is built for A/C systems that require controlled refrigerant expansion ahead of the evaporator. By slowing refrigerant flow at the correct point in the HVAC circuit, it supports proper cooling performance in the cabin. This part cross-references DENSO Auto Parts 475-0503 for the same application. Global Parts 3411895 is listed for select Acura RL and Lexus models with screw-on fittings, making it a focused replacement for service work on these platforms.

What It Helps Address

• Weak or inconsistent cabin cooling
• Improper refrigerant metering at the evaporator
• A/C performance loss after system service
• Restricted flow caused by a worn expansion valve/orifice tube
• Service-related contamination in the HVAC refrigerant circuit

Installation Notes

Verify the vehicle’s A/C fitting style before ordering. This part is listed for screw-on fitting applications only. During A/C service, inspect the surrounding refrigerant circuit, evacuate and recharge the system to specification, and replace the expansion valve/orifice tube whenever the system is opened for repair.

Quality Assurance

Global Parts recommends replacing the expansion valve/orifice tube each time the A/C system is serviced to help maintain proper refrigerant control and cooling performance.
