Cafelat E61 Silicon Gasket 8.5mm
For Lelit Biancas, MaraX, Decent.
The Cafelat 8.5mm E61 Blue 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.
What is the difference between 8mm and 8.5mm Group Seal?
The thickness of the gasket will determine the “lock-in” position of the portafilter handle. Ideally you want the handle to lock in directly towards you (6 o’clock position). If the gasket is too thin it will lock in too far. If the gasket is too thick it will not lock in enough.
