Hello all,
I have been searching through about this OPV as well, since I have an Xstream 1st serial 0120, and a Jetstream 1st serial 3960.
I have omniswivel currently installed on my Xstream 2nd, planning to change all hoses to miflex.
But do these regs has OPV?
Cheers in advance
As i remember, te 3960is the flat bottom first stage, and if it is, it have built in OPV.
