FastRack 3-Piece Airlock Set for Fermentation (Set of 2) | Includes Transparent Airlocks and Drilled Rubber Stoppers – Hydrolocks for Fermenting Beer, Wine, Mead, and More | Fits Carboys & Fermenters

Used this airlock for a batch of ginger mead and it did exactly what it was supposed to. Fit securely on the bottle and handled the fermentation process without any issues. Simple, effective, and just what I needed for a clean ferment.

item as described works as it should

Before purchasing these bung and airlock sets i was a bit worried if they would fit my carboy openings.But when I tried them, they fit in both my 1 gal and 3 gal glass carboys.Very easy to disassemble, clean and sanitize.The airlocks will fit all the way inside the rubber bung, if you leave them like they look in the picture they seem to be a little loose, so i always press them all the way in to be on the safe side.There is a fill line on the plastic airlock so you can see how much sanitizer or vodka to add.The hole in the rubber bung is small but BARELY big enough to fit a 5/16" tube for a blowoff hose. (This took me about 10 mins and a lot of elbow grease)

Good product

Both came absolutely crushed, 100% unusable.

I purchased one set of these, and they work so well, I purchased another set very soon after. Thanks to a review by another customer, I modified plastic mason jar lids to fit these (made holes with a Dremel and smoothed and refined them by hand with sand paper), and they are working great! Yes, they are inexpensive, but they don't feel cheap, and I expect I will be using them for a long time to come. It's cold where I live, so fermenting sauerkraut, pickles and sriracha can take quite a long time; with these installed on my lids, I haven't had to worry at all about mold forming or manually letting the gasses escape. A small price to pay for peace of mind!

The plastic is cheap and will not stay in a bottle. It kind of does what its meant for but be careful cause it will come out when a fly hits the bung.

This is by far not the best quality but if you're beginning wine making then this would suit you I have had no problems so far
