Masontops Pickle Pipes - Airlock Fermentation Lids - Fermentation Kit For Wide Mouth Mason Jar Sauerkraut & Pickle Kit - Fermentation Jar Not Included

Excellent product. Perfect for fermentation. Extremely durable and work fantastic. Will definitely be purchasing more of these. They are a bit expensive for 4 of them. But they are easy to use and have made fermenting foods easier, as the jars burp themselves.

Great product. Just made my fermented cabbage and these mason tops work perfectly.

These silicone tops are the easy solution to "burping" fermenting hot sauce or other foods. They fit the jar lid well and provide both the seal and "relief" through a slip in the nipple on top. Easier to use than fermentation locks, but I use both

Perfect for making Sourkraut!!!! I cannot believe I struggled for so long trying to cover while fermenting This is the perfect product

Pickle pipes work well.

so easy, I can burp my jars without introducing air

I chose this particular item for my first foray into fermentation. The lids arrived next day after my order and were included in solid packaging along with some fermentation weights. After a quick wash and dry, the first quart of fermented red onions was underway. The lids fit as expected.

Exactly as advertised and will make my fermentations even easier. No having to remember to burp the jars. If something comes up and I end up out of town for a day, I don’t have to toss it out in fear of something exploding all over my kitchen. Recommend for all levels of fermenters.
