• Description:

  An AC line o-ring (73039TA030) is an essential component of an engine cooling system. The part is located near the pressure valves of the condenser, and it contains pressure and fluid. The AC o-ring creates a strong sealant that ensures the proper flow of water, and its circular shape is suitable for both static and dynamic use. For instance, it is often used in AC systems to prevent refrigerant leaks.
