Craft A Brew 4602x3.4616x3 3ct. - S-Shape Airlock with #6.5 Stopper - Set of 3 (Bubble Airlock)

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.

FYI, they are made of plastic like a soda bottle. They seem pretty sturdy. The stoppers appear to be silicone, and are much lighter in color than they appear in the stock photo. I don't know what kind of bottle you're using them for, but I'm put them in 1/2 gallon growlers and they fit just fine.

Work just as you would want them to.b

Price is right . Bungs are good (soft rubber so it will seal). The airlocks are thin walled so be careful with them very thin plastic. They work well.

I've canned for years but decided to embark on a new project...winemaking. I had gallon glass.jars and glass jugs, but needed the other supplies. These worked perfectly in the glass jug. I've also seen them used in the lids of the gallon wide mouth jars; this requires a little drilling, however.

Functions as expected

Nothing arrived broken but I can see how people have had problems with this. The bubblers are very thin and cheaply made. The bungs have the wrong sized hole, as if the were made for different bubblers altogether. I would suggest that you insert the bubbler into the bung before inserting it into your carboy. Otherwise you might break the neck of your carboy, or the cheap bubbler, itself.

The bubbler tops were fine, worked like any other. The bases however were exceptional, had enough give to be useful with various glass jugs. Will only buy these from now on.
