3ct. - S-Shape Airlock with #6.5 Stopper - Set of 3 (Bubble Airlock) (Limited Edition)

These stoppers and airlocks are cheap, but they work well. Simply fill them with a little vodka (for ensure sanitized) and let them bubble away. These fit growlers well (1/2 gallon), and would probably fit most gallon glass containers, but I can't say for sure. I did notice the rubber stoppers had an intense rubber smell that might have permeated one of my brews. I will definitely soak these for a while to get rid of the rubber smell before the next round.Pros:(1) the price is right(2) works well(3) tight sealCons:(1) somewhat flimsy - made of cheap plastic - but as long as they hold together I'm alright with thatI would recommend these. They do the job well, and the price is right.

What can I really say about them? The stoppers fit my 1-gallon carboys and they help me make booze...Seriously though, almost all of my supplies for making wine come from Home Brew Ohio. Even if you manage to get a hold of an S lock that is split or cracked out of the box, a single message to them sets things right.

A good set of air locks. This size stopper seems to fit better on 1 gallon jugs than the # 6 stoppers that we’re sold to me by my local brew store

Two of the three had manufacturing defects out of the box.Cracked, split, melted, and broken jagged unfinished edges. Thin cheap plastic with ZERO quality control. Bungs are too small for any standard carboy. In short, pure garbage.

Picture shows the stoppers, which were not included. These work ok, but are a pain to clean. I've used them for making fermented hot sauces and they do ok, but there are better ones out there.

with out the little thing I could not have made this wine it 12% and kick ass

Used this on my last batch of beer and they worked however if done incorrectly the pressure can push the fluid out and allow contamination into the fermenting beer. While I may still end up using these occasionally I still prefer the three piece airlocks.

I was worried that they would be a tight fit in my gallon jug, grabbed my ruler and I thought I might have to shave them just a bit to fit them in securely, but they fit perfectly well.
