Carboy Cap- 6.5 Gallon Carboys

Carboy Cap- 6.5 Gallon Carboys

SKU: 7020



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.

Note: This item is only compatible with glass carboys.

Best Purchase so far
This thing is awesome, I just stick my racking cane in and blow into the other side, siphon starts itself and doesn't stop!!

Good Product
I thought I would try this with tubing for a blow-off tube instead of just a big piece of tubing. Fits fairly well on the 6.5 gal carboy, i do wish it was a bit more snug, but think it is tight enough to keep air out. I think this should work fine for a blow-off on a primary.

Nice addition to beer gear
Nice thing to have for your carboy. I get tired of having to clean and sanitize a stopper and airlock so this is just the remedy. Good for popping on your carboy and transporting. Also good when you have a bit too much wort in your carboy and need to add a blow off.

Good price, but not a snug fit and holes are too small for racking cane
Bought it for my 6.5 carboy, and was disappointed to see that it did not fit very tight around the top. It works, but it seems a little too loose. Only other complaint is that the holes are extremely small, and do not fit the racking cane like the instructions say. I really had to stretch it out in order to get the racking cane to fit._x000D__x000D_One great feature is that the siphon can be started by blowing into the other hole, no auto siphon needed. Check out Google for some good videos and pictures on how to do this.

It is what it is
I have 2 of these for both of my 6.5 gal. carboys. Fits snuggly and is actually a little difficult to get off. I run a 1/2" SS thermowell down the middle and a length of 3/8" silicone tubing off the side as a blow off/airlock. Works perfectly.

Works well but the finish could be better
This fits well on my more recent version Italian 6.5 carboys(glass large threaded necks). I use it as a blow off and have not have any problems yet. Once fermentation calms down i switch to a standard bung plug and airlock. The finish quality could be better on the inside, it is very rough inside. This makes it more challenging to clean and sanitize.

works alright
I wanted to use this for blow off tubing. It isn't an ideal fit, but it works. Like one reviewer said, it is rough on the inside. I hope this doesn't help harbor bacteria or yeast. Sanitize well. It is pretty cheap.

Mine doesn't fit tight
Mine doesn't fit tight on the top of my 6.5-gallon carboy, so I have not gotten any use from mine. Hopefully it was just an oddball defect and others have had a better experience. I have had no problems with the functionality of the rubber stopper style, so that is what I have been using.

not worth it
do not buy this. I have 2 6.5 gallon carboys. Doesn't fit air tight on either. Doesn't work with a blow off tube or an airlock. a most disappointing item.
