O ring colour means squat Im afraid. manufacturers colour all sorts of O rings.
I've seen all sorts used with Pure O2 (Viton, EPDM, Buna) quite happily, although I tend to see some dusting on the Bunas. For my gear, I just use EPDM throughout, saves messing around (ie I service everything on the HP side for pure O2). For second stages, I dont bother farting around, they get whatever they get.
