I'm looking for a reg to use for an argon bottle, either one of the dedicated argon regs, like the Salvo or Oxycheq. Or a regular unbalanced piston first stage like a Mk2 or Oceanic SP5 etc. My only requirement is it must be a DIN fitting.

Thanks,
Jim

Oh man, Shoulda said something today. I have a scuba pro. Needs an O-ring or two.
