50 PCs Silicone Grolsch Gaskets Washers High Pressure Leak-proof Seals for Ez Cap Swing Flip Top Bottle-Red

The fit and seal are perfect. The original seals on my Yeboda bottles were getting old and didn't seem to contain the CO2 like they used to. These seals solved the problem and seem better than the originals.

Easy install and fit perfectly! No leaks when I shake the liquid inside. Would buy again except I have enough to last a lifetime now haha

I bought these to use for home brewing of beer. I have arthritis in my hands and have difficulty putting on and taking off the O ring gaskets. I used them for my most recent batch and they worked fine and are really easy to put on and take off.

seems like a good product but i did have one break on me but the seal was still ok to keep the beer fresh. Maybe i was too rough with the closure.?

I use these over guitar/bass strap buttons to make sure the straps don't fall off during gigs. They work great and are super cheap!

I have some swing-top bottles that I use on a daily basis. The hard plastic washers eventually loosened and came off or broke. These solved the problem and IMO, are superior to the washer type bc there is less touching with fingers required, so more sanitary. Makes a nice seal. MY only problem is that they are small and now I don't know where I put all the extras. Ha!

I tried these because the more traditional rubber seals don't hold carbonated beverages reliably. I am happy with these but actually prefer the design of the green ones with no hole in the middle. I needed the different colors to distinguish the different brews.

Using these for carbonated bottled homebrew. Upon first look/touch they feel much nicer than the gaskets that came with the Grolsch-style bottles I purchased on Amazon. Hoping it will protect the plastic stopper from obtaining staining/flavours from multiple batches, since this variety seals over the entire bottom of stopper.
