Nitrogen cylinder regulator

[alia176]

I have three regulators at the house and was wondering if any of them can be used for a Nitrogen bottle.
I have:
Argon/CO2 bottle regulator
Oxy bottle regulator
Acet bottle regulator

Thanks.

Oxygen... Done it, works great.

Argon should have the same CGA stem as other inert gasses, like nitrogen. Otherwise, it is just a matter of changing stems on the other high pressure regulators. An acetylene regulator may not cut it.
