Cafelat Nuova Simonelli 8.3mm group gaskets are made 100% 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, this is what you are potentially consuming with each drink.
Cafelat have spent months testing and adjusting the material so that the silicone gaskets have the same compression strength as rubber, but are also softer so that it is easier to create a good seal.
