Vacuum Leak Testers Easily Locate Tubes for Replacement

The Vacuum leak tester KVLD-3000 is the only tool you need to discover your leaky tubes that require plugging or replacement. Using vacuum technology, the tester gives a reading for each tube that it is inserted into. A steady reading indicates that the tube is well sealed, while a drop in the reading is indicative of a punctured or leaking tube.

The tool is easy to operate, whether you are dealing with boiler, condenser, or heat exchanger maintenance, and it will decrease the time and frustration of locating holey tubes.
