If the fitting a cga 320 male? My regulator is only made to attach to a standard 20oz paint ball tank. I am trying to find an adapter so I can use this tank with my regulator. The regulator I have is from Green Leaf Aqariums http://greenleafaquariums.com/products/gla-mini-ss-paintball-co2-regulator.html.

These are standard CO2 tanks with, I believe, 5/8"-18 threads. These will not fit a paintball size threading. We do sell an adapter that may work for your needs.


Have a great day!
