garbage
The hole is too big for the supplied hose, so no seal is possible. So now I have a length of hose that is too short to be of any real use, and a stopper with a hole that won't even hold an airlock. Ridiculous.

Home brew
I use to brew a lot of beer years ago and still had most of my equipment stored in the basement.Just decided to start doing again forgot how good it was. Had to get a few parts I was missing and really glad I found this sight. Great prices and fast service. I would reccomend this company to anyone that brews beer!

Works great and IS a great fit
This product works great and really is a great fit, regardless of what you read in the 1-Star reviews. When you insert the bung into a Better Bottle or Bubbler with the "loose" tubing already in the bung, an amazing thing happens...the bung compresses a bit, as rubber does, and tightens the tubing inside the bung hole. So 1-Star reviewers, you can essentially "blow it out your bung hole."

Works perfectly
At first I was a little worried as the tube was slightly loose in the stopper, but operationally it seemed to work perfect. I would prefer a lip at the top of the stopper though, as it would be easy to push it too far in to get out easily.

Works amazingly well
I jumped on the 2 for 1 deal with the Bubbler carboys & picked up one of these so I could use for primary.I have to admit I was quite worried about the blowoff tube getting plugged (since I'm used to working with the 1" tube on glass carboys).I just put a batch of Winter Warmer into primary on Saturday & it is working like a charm. I did see problems with the bung slipping at first, but I also just set it on top of the carboy for a few minutes & inserted it once it was dry. No problems.

hole is too big
This is basically useless since the hole in the plug is drilled out too much so the hose just falls through it.Usually when something is overpriced it's because it saves you having to do it yourself. This is not the case here.

Too loose
I had same issue as others where the stopper would not stay in the bottle. Just moving the tube slightly would pull the stopper out. My last batch I really pushed it down and nearly was unable to get it out again. Why can't anyone get the Better Bottle Big Blow Off Closure? I can't find it online anywhere.

worthless
doesn't fit tight at all. It just slips out. No seal at all.

plugs more easily
This set up does seem to plug more easily with the smaller diameter tubing than with a 1" hose set up usually used on a glass carboy. Ideally a 1" hose could be adapted to the Better Bottle.

Not worth the price
Very disappointed with this purchase. The hole was oversized and the tube just barely would stay in. A regular drilled No. 10 stopper and a three piece airlock with tubing attached to it makes for a much better set-up. I will say though, the Better Bottle deal I got from NB was well worth the price.

What is the ID / OD size of the tubing?
A shopper on Apr 22, 2017
BEST ANSWER: The tubing is 1/2" ID siphon hosing which is technically 7/16 ID and 9/16 OD
It says this blow off assembly is for PET fermentors. Why can it not be used with glass carboys? What should be used with glass instead?
S T on Sep 14, 2015
BEST ANSWER: The PET blow off will only work for PET carboy because the opening is larger than a glass carboy

so it will not fit in the opening. For glass carboys

we sell a large hose that fits right in the neck as a blow off: http://www.northernbrewer.com/shop/1-id-blow-off-hose
