Dunk Tank Leak System is a technique for checking for leaks in a component vessel or cavity. By immersing a gas-charged part in a tank to determine if a stream of air bubbles escapes from the part, the test finds leaks. This test is conducted on the vessel's interior using a Dunk Tank Leak System, which uses pressure decline over time to find leaks.Commonly utilized for dunk testing, compressed air will test the component at various pressures and times.
