Without some form of gasket, the Mason jar plastic lids are not airtight. Quality Reliable Products Mason Jar Silicone Seals fit snug into Mason jar plastic lids. QRP seals provide a perfect airtight, anaerobic enclosure while fermenting Pickles, Kimchi (vegetables) or Kombucha (tea). QRP SEALS are designed wide enough that they seat firmly against the roof of any brand Mason jar plastic cap completely underneath the grooves and cannot fall out while screwing the lid onto the jar. CAUTION: OVERTIGHTENING COULD DAMAGE THE SEAL AND MAKE IT DIFFICULT TO REMOVE THE CAP! The QRP Stopper provides a "quick close" for storage when the fermentation process has ended as opposed to removing the lid and replacing with another cap, which allows too much oxygen into the jar. Metal vs. Plastic Lids use for fermentation and storage of fermented foods? We find that whatever we are fermenting doesn't normally come in contact with the lid during fermentation, however can briefly come in contact with the lid during storage. We've done the research, which reveals that metal shouldn't be used during fermentation, nor for storage of fermented foods due to possible corrosion. We use these Fermentation Lids for fermenting Kimchi, and during the second stage fermentation of Kombucha in Quart and Half Gallon Mason Jars.

Great for fermenting
These lids are great. I haven't had any problems with them at all. They screw on easily and come off easily. All my ferments that I have made using these lids turned out really well. I highly recommend them! They are easy to clean, and they look nice too.

... "Fermies" as I affectionately call them & I do like them. Got 2 pkgs to have plenty
I'm using these lids for my "Fermies" as I affectionately call them & I do like them. Got 2 pkgs to have plenty. One split at the hole when I put the airlock in it . Was a tight fit. Otherwise I'm satisfied.

Good purchase, inside bung's are slightly loose.
Happy with purchase, fast shipping. The large "bung's" inside of the caps are slightly loose, and fall out when tipped over. However, I am pleased with this purchase. If only the bungs were a millimeter larger they would be snug. I recommend this seller and their good product.

I love these lids
I love these lids! They are my go to lids for fermentation and I always have a glass of tea in hand with a lid and straw in the car. Will order more as needed.

Absolutely great
These are perfect for making kimchi and sauerkraut! Just stick an airlock in the top and let'er rip! Once done fermenting, stick the included plug in the hole to keep it sealed. I thought about making them myself but why go through the hassle of buying a drill bit, drilling, assembling all these pieces? Just to save a few bucks? I bought it premade and it was worth it!
