Vacuum Leak Detector

Pin Point Leaky Tubes - 1/4 to 3-inch Outer Diameter

The Vacuum Leak Detector (VLD) is a simple test instrument used by manufacturers and users of condensers, heat exchangers and other tubular apparatus to identify leaky tubes. One man does the job. He seals the far end of each tube with a snap type tube plug, then he presses the rubber-coated nozzle into the near end of the tube and depresses the trigger. Compressed air flows through a venturi chamber to produce a vacuum in the tested tube. When this vacuum reaches a satisfactory level, he releases the trigger. A steady Gauge reading indicates a good tube. A falling vacuum indicates a leaky tube. Using a 90 psi dry clean air, a typical tube (1-Inch Outer Diameter x 20 Gauge and 20 feet long) can be tested in 6 to 8 seconds. The tool weighs 2 1/4 lbs. and is equipped with a muffler, so it operates quietly even in confined areas.
