Acid Carboy Cap- 6.5 Gallon Acid Carboys

SKU 7020



Product Details

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:The Acid Carboy Cap for use on older style 6.5 gallon acid carboys with the threaded tops. 

This Cap is too small for our current 6.5 Gallon Carboy (U7007) with a standard neck. See our Standard Carboy Cap for that carboy.

they fit good an easy on off

Does not fit

Useless. Does not fit either of my 6.5 gallon carboys.

So glad I got this

I was using a rubber stopper that always wanted to pop out. Most times I needed to do a heavy tape job around the stopper to keep it in. Big hassle anytime I wanted to check gravity. This cap fits perfectly snug...seems to be airtight as my blowoff tube bubbles like it always did. I don't recall the size, but I had some tubing laying around that fits around the smaller cap stem for very easy blowoff tube setup. Best $4 I ever spent.

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.

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.
