The filler has a tapered fitting that accommodates 5/16”, 3/8” & 1/2” siphon hoses.
To use, simply attach the siphon hose to the spigot on the bottling bucket & filler unit, turn the spigot on, push the button on the filler & 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.
