I have 2 of these;

Does anyone know if they can be used / cleaned for O2? Maybe a rebuild kit that's good for O2? I know they sell O2 ready regulators, but I don't really want to spend more if I don't have to.
My plan is to use one specifically for O2 PP blending mixtures higher than what my stick can do through the compressor (so really anything higher than ~ 40%). My end goal would be to set the regulator at whatever psi is needed for whatever mix I'm shooting for and open the needle valve so it's slow as a snail getting to where it needs to go. I'd like to do other things while filling with O2 then sit there and babysit the gauge as it s-l-o-w-l-y creeps up to desired pressure.
I don't PP blend all that often, but when I do it's a painstakingly slow process.
Is this a bad idea? If so why? I have very limited experience with using a regulator, but since I have 2 I'd like to put them both to good use (the other is in my fill panel).
