5ct. 3 Piece Airlocks with 10 Grommets,Brewing Airlock Kit,Airlocks for Fermenting Air Lock Ferment for Beer Wine Making

Perfect. Uses 1/2 inch drill bit for grommet

Great bottle airlocks works just fine

The airlocks and grommets are of excellent quality. Sadly, no instructions were provided. I began drilling a small hole then try to fit the grommet. Increased the bit size 2 more times until the grommet seemed to fit. Great for any fermentation, pickles, sauerkraut, wine.

This is a good product for fermenting foods. I have used them before and just needed more. Thanks for the quick delivery.

I got these for my husband and he said they work great!

It’s work very well

I use these on quart mason jars to ferment hot sauce and sour kraut. The only reason I didn't give it a 5 star is because it should tell you what size drill bit you need to make the hole in the cap.
