Product Description
ACDelco Professional A/C Orifice Tubes, which separate the high and low pressure sides of the air conditioning system, control the flow of low pressure liquid refrigerant into the evaporator. The orifice tube is essentially a calibrated restriction located at the inlet to the evaporator and is the ideal high quality replacement for your GM vehicle. This causes the necessary pressure drop to allow the liquid refrigerant to evaporate within the evaporator and absorb heat. Since the orifice tube is fixed, the system is regulated by either cycling the compressor clutch or by a variable displacement compressor. This Professional, premium aftermarket replacement A/C orifice tube is manufactured to meet or exceed your expectations for fit, form, and function.
