If you are using any of the other fittings you have to use a thicker o-ring. The o-ring is a USA standard #9. Some guys from overseas have had issues finding that exact o-ring. Vapor did post measurements, but I forget exactly where.

I did a quick google search and found these measurements. I'm not positive they are correct though: 5/8"OD x 7/16"ID x 3/32" wall

Some guys have taken the o-rings off the included fittings and stacked them on the o-rings from the other fittings and haven't had an issue that way.
i changed the O-rings on my bp fittings with thicker one's that not the problem.
the one's that came with the res leak like hell!!

the res leaks at the mounting to fit it in the case !!
