I belive that you can use normal O rings but that they will
detererate
faster when used in a high O2 environment. This means more regular serviceing
or a greater chance of an O ring failure.
Yes, O2 is used in a lot of places where there is oil around, but
they also have acedents in these places, so why take the risk?
