ACDelco Gm Original Equipment Air Conditioning Orifice Tube

The ACDelco GM Original Equipment A/C orifice tube (also called an air conditioning expansion tube or refrigerant metering orifice) is a key part of the air conditioning system. It meters liquid refrigerant into the evaporator, so the system can cool the cabin efficiently.

Key Features:

• GM Original Equipment quality from ACDelco, GM's official parts brand
• Meters refrigerant flow into the evaporator to support proper cooling performance
• Built-in filter screen helps catch debris and protect downstream A/C components
• Designed to meet GM specifications for fit, function and durability
• Compatible with the refrigerant systems the part was engineered for

A worn or clogged orifice tube can cause weak cooling, system icing or uneven performance. Replace it when you service the A/C system, such as after a compressor replacement or a system flush. Along with the orifice tube, it is good practice to replace the accumulator or receiver-drier and to evacuate and recharge the system to specification.
