DetailsTo 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.
Note: This item is only compatible with glass carboys in 3, 5, 6 or non-acid 6.5 gallon sizes.

4 months agoWorksUsed to remove airlock and use tin foil for cold crash now I just sanitize and pop this on top. Havent got the chance to ferment with it yet but appears you could just stick a hose right in and run to a container of water and never remove your top for cold crash again.April 3, 2019Purchased

9 months agoGreat for use as a blow off tubeWorks as it should. Fits well on a standard glass carbon, even under an over zealous fermentation as a blow off tube.Works like it is intended, fits well even under pressure!September 14, 2018Purchased
11 months agoGood StuffI picked up one of these to convert a 5 gallon water bottle I had on hand. Saved me the cost of purchasing a carboy, the Racking cane fits perfect as did the vapor lock. I will buy this product again to outfit the other two 5 gallon bottles I have in storage.February 3, 2017Purchased
over 2 years agoRethinking this oneIt leaked. Had a pin hole in top which I fixed with a hot poker. Also had to put several rubber bands around circumference to seal completely.February 3, 2017Purchased
over 2 years agoMakes siphoning a lot easierUsing a racking cane, I use a quick blast of CO2 to get the siphon going rather than blowing into the tube.January 29, 2014HandycapI know this isn't supposed to be used with the better bottle,but I got one & it fits snugly. I put the airlock in the center tube for one week oaking,etc. Working just fine so far on my 6G BB.November 26, 2013

Browse 3 questions Browse 3 questions and 9 answersWill this fit on a 5 gallon plaster water jug? Like the ones you use in a water dispenser?BEST ANSWER: I really have no idea, I use mine on glass bottles and not plaster bottles, or plastic.Can you attach an airlock to this instead of a blow off tube?BEST ANSWER: Yes, I do. Much easier to take on and off than the other types and it stays upright when you set it down with the airlock while testing.Will this fit a 6 gallon Bubbler plastic carboy?BEST ANSWER: I think the bubbler OD on the opening is just about the same size as the glass carboy so it should fit. I also use a clamp on mine to keep it tight for making sour beers and adding a CO2 blanket to the carboy.
