OIL GUARD

Oil Guard – By-Pass for System Diagnosis

Oil Guard is a diagnostic devise for verifying the general condition of a vehicle A/C system, simply by connecting to the high and low-pressure ports of the A/C system. Through the Oil Guard glass it is possible to visually inspect the presence of chemical additives such as UV leak detector dye or A/C leak stop, as well as the oil/refrigerant gas miscibility. It’s therefore possible to evaluate the quality of the oil, and the possible presence of water or other contaminants.
