Looks like all those adapters are to fill the paintball tanks from the bigger bottle. I suppose they will work to extract gas from the PB tasnks, but the fitting will be backwards for your beeer regulator.
Hye, my 5# tank is an old fire extinguisher. Somebody had the valve changed and the tank re-hydroed. Probaly cost $25, plus the fill. For a swap meet buy of $1?
So far, I've had more experience thinking than I've had brewing....you don't think they are mutually exclusive, do you?
57 batches so far,
33 wine, mostly Loquat, peach, plum, prickly pear
22 beers and ciders
1 Tequila, from a prickly pear wine experiment that didn't work. I call it "Prickly Heat"
