ACDelco 15-50120 Professional Air Conditioning Orifice Tube

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 high quality replacement ideal for many vehicles on the road today. 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 your expectations for fit form and function.
