This Vacuum Plug allows you to test your watertight enclosure for proper seal without getting wet! Here’s how it works: the barbed end is connected to a handheld vacuum pump and vacuum gauge and then you insert the other end into the vent on the enclosure. By pumping the vacuum pump, you’ll remove air from the enclosure, which simulates the same external pressure that the enclosure would experience a few meters under the water.
