LACO offers several standard leak test Helium Bombing Chambers & Systems used for the leak testing of sealed objects. Our standard bombing chambers are also used for manual or fully automated leak test bombing stations that include all the components you’ll need for a complete turnkey system. Combined with our leak detector inlet vacuum chambers and TITAN VERSA Helium Leak Detector, LACO can offer a comprehensive leak test solution.

Our standard bombing chambers can be easily customized to meet the needs of your application. Our applications engineers can also design manual or fully automated leak test bombing systems to meet your unique requirements.


The bombing method is used to leak test sealed objects that cannot be connected directly to a leak detector. The part is placed in a chamber containing pressurized helium, allowing the helium to penetrate the part. The part is then tested in a vacuum chamber connected to the leak detector. Important considerations include pressurization time, helium bombing pressure, internal volume and leak size.

Helium Bombing Stations are ideal for manufacturers of small sealed electronics and other hermetically sealed devices which must be bombed with helium prior to leak testing. Stations are designed for either manual or fully automated PLC operation using LACO’s ATLAS Leak Test Process Controller.
