3-Piece BPA-Free Plastic Airlock Bubble Airlocks for Fermentation, Black Silicone Fermenter Lid Grommets 5/8" OD, 3/8" ID with #6 Hole Rubber Airlock Stopper Plugs for Beer Wine Sauerkraut, 12 Pieces

These work alright, but the holes in the stoppers are very small, so you can't use them for standard sized tubing, only the airlocks. Even some of the other airlocks I have don't fit well. The stoppers seem pretty cheap as well. They tend to pop out of the top due to the material they're made of. I chose this due to it's low price though. Have ended up giving the stoppers away. The gaskets aren't very tough either, so be sure to sand the edges of any hole you put them in.

The ones I recieved were foggy and felt kind of cheap. But, I guess you get what you pay for in this case. Still worked for my mead.

Came quick, basic water seal. You c as n tell cheaper plastic that ones I bought at wine store. Size 6 plug doesnt fit 5gallon car boy. Also HIGHLY suggest using 1/2 drill bit. Worked way better.

Does it's job

These corks are made of silicone so they slip right out of jugs, if they are not completely dry.

I have used them to make fruit wine and red wine. The wine is very good. These tools are able to isolate air and bacteria. It is a good wine making tool.
