If I had the right fitting I could.. I can’t get them as full as the commercial guys do. They use a pump to fill them.
I do not have the right fitting to fill those.I need one for a soda machine but I've about given up finding a place. It's the same as used with paintball. Ever place I called doesn't do them any more. If you find a place let me know.
Randy mine is a standard fitting you think you might can do.it. I can send a pic.
