As long as you get a regulator that has the correct stem, you should not have any problem replacing just the nut...though now that leads me to thinking whether the CGA320 stems are compatible with DIN nuts.
Do you have dimensions/pictures of the DIN nut? I am quite curious about this now.
I have pics of a DIN 477 #10 (nitrogen) nut and nipple in this thread: Linde regulator question (German model)
I was asking for help to convert that regulator for CO2 use in the US.
