Looking for an O2 Regulator

[Ironflight]

I'm working on a "special" O2 system, and need to find an Oxygen-safe first stage regulator that will screw onto a standard CGA-540 valve (typical Aerox portable bottle) and put out from 50 - 100 psi through a standard pipe-thread-type fitting (to which I can connect a medium pressure hose).

Searching the 'net is tedious with these requirements - we've got so many folks here on VAF, I figure that someone might pop up and say "hey, I make those!"

{Once I have the 50-100 psi O2, I'll pipe it to a second-stage diluter/demand regulator that I already have. I have used a borrowed bottle/reg for the front end of this before, but that isn't always available to me, so I want to roll my own that will work with bottles I have for our canula systems.}

This is not a scuba first stage regulator you are seeking? I can help if it is. I did this to use for emergency strut inflation with scuba tank for my 310. 310 is gone.
