Helium - Wikipedia

One industrial application for helium is leak detection. Because helium diffuses through solids three times faster than air, it is used as a tracer gas to detect leaks in high-vacuum equipment (such as cryogenic tanks) and high-pressure containers. The tested object is placed in a chamber, which is then evacuated and filled with helium.

Helium Leak Testing - Applied Technical Services

Clients may request helium leak testing to assess the performance of a material or to analyze or evaluate component longevity. Helium is the preferred leak testing medium because technicians can detect and measure it at minute leak rates (less than 1 cubic centimeter/300 years) and because the gas is inert, meaning it will not react with most components being tested.
