A pressure leakage detector includes a primary gage and a secondary gage selectively connected to each other by means of a valve. The primary gage is connected to an air compressor via a pressure regulator for regulating the pressure supplied thereto and has an outlet port adapted to directly continuously supply the pressure to a large container to detect the leakage of container by means of visual inspection. The secondary gage has an outlet port adapted to connect to a closed system on which a leakage detection is to be carried out. By opening the valve between the two gages to have the closed system reaches a predetermined internal pressured set by the regulator and then closing the valve, a leakage of the closed system may be found by a drop of the pressure reading of the secondary gage. Thereafter, a visual inspection will indicate the exact location of leakage. Thus a precise and correct detection on either a small volume closed system or a large container may be preformed in an quite easy manner.
A pressure leakage detector comprising a primary four way connector having a first, second, third and fourth ports and a second primary four way connector having a first, second, third and fourth ports, a primary pressure gage being mounted to the first port of the primary four way connector and a secondary pressure gage being mounted to the first port of the secondary four way connector, a valve being connected between the second ports of the primary and secondary four way connectors;
