Vacuum testing and the vacuum tester failures


(Julian Hancock) #1

Hi

The vacuum testers I use turn out to be a failures after a while. Can any one recommend a bullet proof version or another method of testing the seals.

Regards

Julian

That was my experience with the brass pumps as well. I ended up getting a “mityvac” (made by Parker Hanifin) which seems better made and hasn’t had issues.

Hi Paul

Looking at their mityvac website is that their hand pumps?

Thanks

Julian

I’ve had lots of luck with this one and it has a way to attach a tube to the valve that returns air that has been vacuumed out of the enclosure. I’m in Florida and humidity is a real problem and I return dry air into the ROV enclosure Vacum

We use the mighty vac as well. We once had some trouble finding an air leak. We rented (for free) a vacuum pump, used to do Air Conditioning work, from Autozone that drew a vacuum so quickly that we were actually able to hear the leak and find that we were getting air through a wire sheath from a leaking external camera. The electric vac also can remove all of the water from the container by boiling it off.
