it is about 30% fail rate for used regs, the chance of both of them fail is weak, but I don't have good faith on them because I had two of the same model brass regulators long time ago, all diaphragm damage.
The same model stainless steel regs that I got were good.
They are the same model of the GO, Swagelok or HOKE regulators, I am not really sure if the actual manufacture is Harris group, because I can't find it from Harris or Airproducts, and of course, it is not a Victor either.
Since it is the same model as GO, I suspect the actual manufacture is in JAPAN, just like those swagelok pressure gauges.
