Hello Tom, The instructions with the one I have say 2 PSI under or over (I forgot which) system pressure, I will look Monday and email. Check the local Fire Extinguisher recharge co. for Nitrogen, They use in in Dry Chemical extinguishers. The one I have has a regular valve stem on it like a tire. Fills with the same adapter as a tire (Same as the one that used to be on Badger Brand Water Extinguishers).
