Looks great, does the swagelok fitting have a stand NPT thread or did you have to use an adapter?

It have an orginal NPT thread on it.

Now I just have to figure out what thread my Subal has. It has an unused bulkhead, sure would be nice to know it won't leak before I dunk it.
How much vacuum do you pull when testing it? and do you plan to leave it at vacuum when diving?
Thanks!

I can get it up to -0,5 bar(-7,5 Psi). Then I leave it about 10-20 min to see if it drops. If you leave about -0,1 bar then you can't get it apart, nice to have when you put the rig through the splash zone.
