Premium Grolsch Style Silicone Rubber Gasket Seals - Extra Thick & High Pressure Full Replacement Washers for Flip Top, Swing Top & Similar EZ Cap Bottles - 12 Pack

High quality material, no smell, no taste and very playable but the circle is cut a little short. They work! but I thought a little overhang would be good under the cap. I'm satisfied, it seals, maybe I'm just a little nervous and looking for the outside flap when the seal is on the inside.

I needed to replace the gaskets on my 16oz e-z top beer bottles (the gaskets are only good for 2-3 bottling) and gave these a try. Excellent replacement. Seal very well.

I love these silicone caps. They are soft and flexible so they are easy to install. They fit the bottles I have from years back. I needed a little bigger opening to fit my bottles and these fit perfect. I use my bottles for water kifer. They creat an air tight closure. I will order these again.

I have placed these on all my wire has bottles. Great seal!

👍

My beautiful bottles were not getting the fizz I'm used to getting from my kombucha, so I put these suckers on and have my wonderful fizz back. Cheers!

Just about to bottle a batch, so far so good.I wish they would make these for Growlers.

Great sealing and keep the bubbles in my kombucha.
