The 4" x 4" Helium Leak Test Bombing Chamber features stainless steel construction, 4" diameter x 4" high chamber, NW 16 vacuum flange and valve, 1/4" NPT vent and valve, 1/4" valve and push tube helium port, and 0-30 inHg to 60 psi compound gauge.

LACO designs and manufactures both standard and custom leak test bombing chambers for the leak testing of sealed objects that cannot be connected directly to a leak detector. We offer five standard bombing chambers that can be easily customized to meet the needs of your application. Our application engineers can also design manual or fully automated leak test bombing systems that include the components you'll need for a complete turnkey system.
