Bottle filler with auto shut off at adjustable fill level. This bottle filler has a tapered fitting that accommodates 5/16", 3/8" and 1/2" siphon hoses. It can be used for bottling both still and sparkling wine. Simply attach a siphon hose from the spigot on the bottling bucket to the bottling filler unit, turn the spigot on, push the button on the bottle filler and the filling begins! When the bottle is full, the unit automatically shuts off. The rubber piece that goes into the bottle can be moved to adjust the fill level. The nut on the top of the unit allows regulation of the flow.
