A larger bottle filler that will fit on larger 1/2" ID tubing. If you have a large Auto Siphon and wish to use it to bottle, this is the bottling wand for you. It does not have a spring in the tip; instead, it has a check valve that drops into place when it is not pressed against the inside of the bottle. Once pressed, liquid will flow, filling your bottles. For a large Auto Siphon, this is the bottling tool you need.
