Manual leak tester for can packaging

Pump for testing the leak tightness of empty cans

Make a hole in the bottom of an empty and closed can. Screw in and tighten the tip of the leak tester (do not overtighten). Inflate the can until the pressure gauge reads 1.5 bar. Submerge the areas to be tested under water and visually check for the formation of air bubbles at the seam.
