I spoke to the tech guy today and we discussed leak testing and he agreed that using nitrogen worked better.
I theorized that under a vacuum, you could completely remove the flare nuts
and it might still hold a good vacuum..

The dilution principle makes pressure testing even better looking..

He also recommended the MasterCool 3 CFM vac pump. Said it had a check-valve.

Anyways, I'm wondering what type and size of flare nuts I'm going to see
on these 5/8" & 1/4" OD lines? Metric or regular?
