MK17/G250V for Nitrox over 50% ?

[jh_MacLeod]

Hi, I know some of you guys are SP regulator experts, so I want your answers to the question.
Is there really any problem with using this reg combination with oxygen concentrations over 50%?
Or problems involved when servicing for this intended usage?
Thanks...

I foresee no problem with the combination you have unless you store them in a oil bucket. I assume you want to use this as deco setup? I would rather use a Apek ATX50/SP R295 or similar instead of the 250. The 250 is large and would rather use that as primary.
