Abstract: A multi-fit, fast connect, bottle-to-dispenser system for connecting a liquid dispensing pump to a liquid reserve has a universal adapter. The universal adapter attaches to a neck of a bottle and has a first fitting and a second fitting being concentrically stacked, wherein the first fitting has a first plurality of ribs of a first diameter and the second fitting has a second plurality of ribs of a second diameter. The first fitting forming a seal with the neck of smaller bottles and the second fitting forming a seal with the neck of larger bottles. A pass through channel traverses through the first fitting and the second fitting, and allows a connecting tube to be positioned through the universal adapter into the bottle. A dispenser coupling is terminally connected to the connecting tube opposite the universal adapter, joining the connecting tube to a down stem of the liquid dispensing pump.
