Review on 🔋 Convenient Maddog CO2 Fill Station: Dual Valve Bottle Refill for 12oz, 16oz, 20oz Tanks by Brad Jeffress

I have 4 cans of 20oz Maddog paint. I bought 3 of these Maddog fill adapters and returned them because the black fill adapter that attaches to the threaded paint canister is too large to properly seal with the o-ring on the bead tank. The only way this adapter will work consistently is to purchase and use a 3/4 inch o-ring that fits between the top of the paint can and the refill adapter. Poor quality control if your maddog fill adapter doesn't work with maddog paint. spherical tanks!
