GM Genuine Parts – Air Conditioning Orifice Tube (Part No.15-5378)

Air Conditioning Orifice Tube

from

$9.49
GM Genuine Parts A/C Orifice Tubes are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These 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. 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. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).

Product Features:
  • Restores A/C performance due to restricted orifice tubes
  • Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE)
  • GM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicle
  • Original equipment parts are designed to work with your GM vehicle safety systems — aftermarket replacement parts may not meet the same OE safety regulations, depending on the part type
  • GM regularly updates production and service part designs to integrate new materials and technologies
