Lanbo Vacuum Leak Detector (VTLD) is a simple test instrument used by manufacturers and users of condensers, heat exchangers, and other tubular apparatus to identify leaky tubes from 5/8 to 1 1/4-inch (15.88 - 31.8mm) Outer Diameter. With the VTLD, one user can seal the far end of a tube with a T-Handle tube plug by pressing the rubber-coated nozzle into the near end of the tube and depressing the trigger. A steady Gauge reading indicates a good tube while 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 25-feet in length) can be tested in 8 to 10 seconds. The VTLD weighs 2 1/2 pounds and is equipped with a muffler, providing quiet operation even in confined areas.
Lanbo VLD can be used with accessory parts, including Spare Nozzes.
