ACDelco 15-30973 A/C Orifice Tube Expansion Valve GM Air Conditioning

The ACDelco 15-30973 is an OE-replacement A/C orifice tube designed for General Motors vehicle air conditioning systems. The orifice tube is a critical component in a fixed-orifice type A/C system, regulating the flow of refrigerant from the high-pressure liquid line into the evaporator, where it expands and cools the cabin air.

As a genuine ACDelco part, this orifice tube is manufactured to the same specifications as the original equipment component, ensuring a precise fit and reliable performance. It features a metering orifice and an integrated filter screen to help protect the system from debris and contamination.

Key Features:

• OE-quality replacement orifice tube for GM A/C systems
• Regulates refrigerant flow from high-pressure side to evaporator
• Integrated filter screen helps prevent debris from entering the system
• Manufactured to original equipment specifications for proper fit and function
• Direct replacement — no modifications required

Replacing a worn or clogged orifice tube can restore proper A/C cooling performance. This part is commonly replaced during A/C system repairs, refrigerant recharges, or compressor replacements to ensure long-term system health.
