"Oxygen Clean"?
Hello. I'm brand new here and haven't even begun working with glass. I absolutely intend to and will post a bit of an intro in the new members forum right after I post this. But as for the point of this thread, I'm putting together an O2 system (details in my intro thread too) and, due to my extreme OCD, am trying to make it absolutely perfect, super awesome, and FAR beyond overkill for my needs. But a term that I've come across often is "oxygen clean". This term has proven to be very limiting towards my build. If only I could find out what I need to do in order to make items "oxygen clean" myself, I'd have like 100x more options for components that I need. I've found glass-blowing/lampworking forums to be the best sources of info on homefill/O2 concentrator repurposing (not to mention, I do intend on giving glass working a try once I do have it setup). Any help would be GREATLY appreciated. Thank you.

Hi Brandon - welcome to LE!
I've been lampworking for many years and have used both tanked oxy and concentrators but "Oxygen clean" is a phrase I've never heard before. I will be interested to read your intro post!

Clean
I was taught to always keep the valve closed when the tank is empty,
preventing anything from getting into the cylinder.
Other than that I have no idea.

"Oxygen Clean" means that any part of a system using pure or almost pure oxygen must have all of the parts cleaned of any petroleum products. Any metal parts that are not made specifically for use with oxygen need to be cleaned of oils left from the machining process, in other words in insides of tanks, valves, fittings, etc.
Have fun & be safe.

The dangerous thing is "pure" oxygen under high pressure in the presence of oils.
KABOOM
Edit: the OP is planning a Homefill setup, so that definitely counts as high pressure. I'm planning a HVLP system and will not be spending much time cleaning parts with acetone.
Edit2: O2 safety guidelines: https://www2.le.ac.uk/offices/safety.../hse8.pdf/view (file too big for this site).
