Masontops Pickle Pipes - Waterless Airlock Fermentation Lids - Wide Mouth Mason Jar Fermenter Cap - Premium Silicone Top

I love these fermentation lids! They are the perfect solution to a simple, but annoying problem. These perfectly fit a wide mouth mason jar, use the canning ring (of which I have collected tons over time), and work exactly as advertised. They're also very easy to "burp" by simply squeezing the top of the pipe to open the check valve. Occasionally when I overfill my vegetable fermentations the brine will come up and out of the pipe stem, but that's on me, and it never flows past the canning ring, only out of the top of the stem. Cannot recommend these enough for fermenting vegetables at home. Going to try this soon for a sourdough starter as well.

I thought I had already written a review :/ Anyway, these do work great but... I had to buy wide mouth jars due to they sent the ones for wide mouth rather than regular :/ I'd love to reorder and get the right ones but don't want to chance the wrong ones coming again. I got these to mainly ferment and make cabbage and kimchi and such. As I said, they do work great but I don't always want to make a huge jar lol... either way I love the colors and they are so easy to clean. I love that there is minimal work when they're being used. So I most likely will eventually order more :)

im using all four right now to ferment. they work so well. i am pleased with my results. two weeks in. when they all burp at the same time it smells like hot sauce in here. these lids make fermenting a lot easier than having to manually burp the jars. they are easy to use. only have to sterilize and put on the jar. the lid does the rest, it automatically burps when it needs to. they are durable food safe bpa silicone. dishwasher safe. i use with ball/mason/kerr wide mouth jars.

As the title says, these are perfectly fine, but I would not buy again.

These are perfect for making fermented water kefir. It's easier to move the bottles around without the liquid splashing out the top.

Where were these when I was a kid? I was in charge of burping jars, cleaning the plates(a whole different process but same principle) and getting gross gunk on my hands.I love these. Fill your jars, add weights and walk away!!!

I’m using these to make fermented feed in wide mouth mason jars, for my 12 chickens as a treat each day. Very easy to use, clean and are reusable.

Los vamos a poner en uso pronto y estamos seguros que nos ayudará a cambiar nuestros hábitos alimenticios para introducir alimentos que cuiden nuestro microbioma.

Funzionano perfettamente anche con i barattoli Bormioli!!! Le ghiere, però, le ho acquistate a parte, sempre qui su Amazon.

These guys are awesome! My Kimchi bubbles quickly, especially in our wood heated house in winter. These silicone ferment lids are durable, easy to clean and hold really well under pressure while still allowing the ferment to off-gass. I have the expensive oxygen pump ones to, but honestly these guys work just as well and are much simpler in design. I find them easier to remove after they have been pressurized by the ferment process, while my air pump ones always lock up tighter then when I closed it. If these ones get super pressurized, they will slip free out of the ring rather then locking up. They are super simple to use to, just fill the jar, put the lid on top, and screw on your ring. These are a Game changer!

I had never tried fermenting anything but I wanted to make Kimchi. I bought these and some mason jars and Googled some instructions and recipes. These things make it so simple that now I’m fermenting everything, including blackberries. I kept hearing about exploding jars and mould - nothing! They take care of themselves. I just filled them, stuck a shot glass in to press everything down, and left them for a week. I bought the smaller size but I will be buying more of both sizes. Really great product and really easy to clean.

Ils sont adaptés à mes bocaux Kilner large ouverture de 500ml. Je vais faire seulement des petites quantités de légumes fermentés. They fit my Kilner 0.5l wide mouth jars. I will only make small batches of fermented vegetables
