3-Piece Airlock 4 Pack with 4PCS #6 Stopper and 8PCS Grommets, Fermentation Airlock Beer Wine Kombucha Brewing Kit,Carboy Airlock FDA Transparency Upgraded

I've made 15 gallons of mead with this kit so far and the only error was user error because I didn't make the hole in my lid big enough it was hard to install and after the third 5 gallon batch the gasket tore. The product itself functions perfectly. I'm glad I have another three gaskets to work with once I expand the hole to the proper size.

Perfect product

Pretty flimsy plastic one cracked after first use

Drilled a 1/2" hole in a 3-gallon bucket lid from big box store, added water to prescribed line, and placed over bucket with pepper mash. Fermented for 30 days, with bubbles escaping as process continued. For the price, can't be beat.

Excellent air locks!

No instructions and poor shipping. My box was open. Like others have said, the grommets are extremely tight. The hole that needs to be drilled into the lid is a half inch due to the size of the airlocks neck when inserted into grommet. I’m not sure the they are the right size for this airlock. The airlock itself seems to be ok. Just hard plastic parts. If you drill a steel lid the edges will cut the grommet easily, I ruined my first one trying to figure out what size hole. Probably would have been better off with a plastic lid or a burping lid. Live and learn.

This worked great for wine fermentation. It is sturdy and easy to wash. My wine turned out great and no bugs got into it. Some of these are very fragile but this one is not. I recommend this for wine making/fermentation. Good value for the money.

These air locks appear to work just fine
