Carboy Caps for 5 gallons


Carboy caps work to seal carboys as an alternative to plastic or rubber stoppersTwo spouts which will accommodate racking and blow tubes, filtration tubes, or fermentation locks.  Put a racking tube through the center spout, fit the cap over the mouth of the full carboy, then blow hard into the second hole to prime a siphon.

To use the Carboy Cap: Push a racking cane through the center tube, place on the top of your carboy, blow into the other tube, and a siphon is easily started. May also be used for blow-off when fermenting. Attach a length of 3/8" ID tubing to the hood, and run the tubing into a bucket of water. When used this way, the carboy cap takes the place of an airlock. 

Carboy caps are useful for making almost anything including beer, wine, mead, or soda.
