This hand-operated vacuum pump allows you to test the seals on a watertight enclosure without getting it wet.

The vacuum test doesn’t test at very high pressure, but it does give you the peace of mind that the enclosures are properly shut and airtight. We usually do this test after opening and closing an enclosure and before the first dive of the day.

The pump comes with everything you need to use it, including the Vacuum Plug.
