Finally, a quality siphon for home brewing, distilling, and wine making. For siphoning out of a carboy, bucket or FermZilla. This siphon includes a 60″ long x 1/2″ interior diameter silicone tubing, and the stainless siphon wand itself is 22″ long. A glass ball is enclosed in the end, which combined with a stainless spring, start the siphon for you when you move it back and forth. Sucking or filling the siphon full of fluid is not required: just dip it into the fluid to be transferred, and jiggle it up and down a few times.

This whole assembly is plasticiser and BPA free and virtually unbreakable. It is made out of 304 grade stainless steel and is easy to take apart for cleaning. Easier to start than a conventional siphon but at the same time similarly simple to use and clean.

Note: Some of the pictures and the video show it with vinyl tubing, but it comes with silicone tubing. Silicone is the best because it can be used with everything from beer to hard alcohol.

INSTRUCTIONS

3: Attach the curved siphon to the hose
4: Submerge the end of siphon into your full container.
5: With long swift strokes shake the siphone tube up and down to start the siphon action
