Went ahead and bought a separate regulator for my Argon tank. Added an 8' 1/4" plastic hose that can go to the bottom of the containers. That way I flood from the bottom then slip the hose out. When the bags are sealed I "squirt" some more onto them prior to sealing the lid. Only caution about using Argon is that it is much heavier than air and needs to be "poured" out so you do not breathe it.
