Why vacuum ? I understand that your customers have usually to do with
wetness, vacuum is not a good way to seal those afaik. The smallest leak
fills the box with water (completely) even if water needs to enter as
vapor because the hole is so tiny.

Don't you tell them to fill it with liquid ? (oil or special) ?
