Hello

In the stages with high percentage of oxygen (for instance – 80% O2) you use specific regulators (the green ones with O2 clean) or the “normal” regulators can do the job?

By “normal” regulators I mean good regulators with the usually announce that support 40% O2 …

Thanks

I would take apart the reg, and clean it for oxygen use. If I was not able to do that, I would purchase a regulator that is already cleaned for oxygen use. I would not use a regulator specified for 40%
 
Most places don't oxygen clean regulators. Until the mix is above 50%, it isn't necessary. If you are using 80%, go for O2 cleaned
