Zazolyne 5ct. S - Shape Airlock with # 6 Stopper 5pcs & Grommets 10pcs,Bubble Fermentation Airlock for Brewing Wine Making Sauerkraut Kimchi (Improved Version)

This product works very well for fermenting wine. There are 5 sets of airtight components. They are durable and reusable. Great for people who do not want to spend a lot of money to start making wine at home.

I use these for making mead, they work great. The measurements were spot on as the fit the jugs I use perfectly. Quick shipping.

The media could not be loaded. These little things worked exactly as described. They come with their own little seals and are very easy to install. Easy to clean but you have to let air dry. Only used once, but I assume they can be used multiple times without any problems. So far a very good purchase!

These work very well I was just surprised that the plastic was so hard and thin.

Before you insert the black grommet into the pre-drilled hole, soak it in HOT water for a bit. Makes it more pliable and easier to fit.

great product

Used for home brewing, seems to work exactly as advertised.

This is a great product for fermenting. Decent quality and easy to clean. Wish the put a couple of pipe cleaners in kit
