Please note that although the gaskets are strong under compression, you should never use a sharp tool like a screwdriver to install them. This may tear the silicone.
Cafelat group gaskets made from food grade FDA silicone. Unlike regular gaskets that are made from rubber these do not have any smell or taste whatsoever, and are easy to change since they will not bake rock hard like rubber does. If you have ever struggled to change an old gasket you cannot help but notice the awful smell and the black soot that comes off the rubber. And that is what you are potentially consuming with each drink.
Cafelat has spent months testing and adjusting the material so that these have the same compression strength as rubber, but are also softer so that it is easier to create a good seal.

We are making these gaskets available as an upgrade, replacing the stock gasket with this one would not be any significant cost decrease, so we suggest if you are interested in this gasket to use your stock gasket as a backup.
