Our new patent-pending self-tapping tank is now available. This tank seals itself, which means you can make your drinks outside of the cooler and drop it in or remove the tank from the cooler with your leftover drinks without ever wasting a drop. Simply drop it in and thread on the spout from the outside to activate. When you're ready to remove the tank to save your leftover drinks or clean it, just unscrew the tap and pull it out. Fits all the 55qt Br
