A Hose for the Ages
This hose is undoubtedly a cylindrical hose of 1" in diameter which fits snugly into my carboy and facilitates the passage of gaseous substances from my brew into the outside world via the hose lumen and not around the seal. I expect it to last for a number of extremely chunky batches, after which point it will grow beskudged and I will purchase another based on its price, previous performance, and all around hose-y-ness. For the distinguishing homebrewer, I proclaim this hose as a paragon of hoses everywhere.

Fitting is quesitonable
Bought for blow off with big mouth bubbler, and though it "fits" the seal is not tight and made me definitely switch to a tighter top after several days

The Amazing Blow Off
My recent purchase of the 1” diameter blow off hose has turned out to be a great experience. This hose was able to handle 7# of peaches erupting with montezumas revenge exploding out of the carboy. Not a single drop escaped to the outer world of the carboy!

Simple and effective. Can not ask for more than that. A must if you are using a yeast starter.

I noticed in the description it states "Fits directly in the neck of standard or acid-style glass carboys (#7003, 7004, 7006, and 7007)", does anyone know which ID fits inside the 1 gallon carboy SKU#7009?
C V on May 10, 2016
BEST ANSWER: This hose would be too large for a 1-gallon jug opening. A good way to have a blow-off tube on a jug is to have a 3-piece airlock held in a #6 stopper, or the screw-cap-with-hole. Take the top and center cap out of the airlock and put a piece of 3/8" tubing onto the center "stem" of the airlock, and drop the tubing down into a cup or container of water. This will make a simple blow-off assembly for fermenting in the jug. -Mike W, Northern Brewer
Will this work well with (non-Big Muth Bubbler PET carboys as well?
J L on Feb 9, 2016
BEST ANSWER: Yes, this fits the Big Mouth Bubbler. When you add the bubbler to the cart you will be given the option to select additional items such as this blow off tube.
Will this work with a Big Mouth Bubbler?
Nick E on Jan 10, 2016
BEST ANSWER: Yes fits nice. It's my opinion that it fits carboys just a little better. But it fits and does the job on the big mouth just fine
does this fit the opening on the Little Big Mouth Bubbler?
Raymon A on Mar 6, 2017
BEST ANSWER: It does on mine. The opening should be the same as a carboy.
Is this food grade?
A shopper on Dec 13, 2016
BEST ANSWER: Despite it not saying specifically so, I have used this hose in a blowoff tube capacity on numerous fermentation runs and have had no issues with it.
Does this fit the standard lid that comes with the 6.5 gallon brewing buckets?
C O on Oct 22, 2015
BEST ANSWER: It does not. It fits the opening of the 3



and 6.5 gallon glass carboys
