Carboy Cap 3,5 & 6 Gallon

Universal fits standard 3, 5, or 6 gallon carboys.

Universal fits standard 3, 5, or 6 gallon carboys. Put a racking cane through the center tube, fit the cap over the mouth of the 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.
