homas C. Wilson's Vacuum Leak Detector (VLD) is a simple test instrument used to identify leaky tubes ranging in size from 1/4-inch to 3-inch outer diameter. Manufacturers and users of condensers, heat exchangers and other tubular apparatus depend on the Vacuum Leak Detector to accurately pinpoint costly leaks the first time, every time.

The Vacuum Leak Detector can be used with accessory parts, including the Wilson Tube Plug Snap for 3/8 to 2-inch (9.5–50.8 mm) Outer Diameter. Additional nozzles are available from 1/4 to 3-inch (6.4–76.2 mm) Outer Diameter and nozzle extensions are available from 5/8 to 2-inch (15.9–50.8 mm) Outer Diameter.

How It Works

One person can easily do the job. He or she just seals the far end of each tube with a snap-type tube plug, presses the Vacuum Leak Detector’s 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 90 psi dry, clean air, it only takes six to eight seconds to test a typical tube (1-inch Outer Diameter x 20 gauge and 20 feet long) with the Vacuum Leak Detector. The tool weighs 2 1/4 lbs. and is equipped with a muffler, so it operates quietly even in confined areas.
