Cafelat group head gasket in silicone for all E61 group head machines.
This is a thicker 8.5mm gasket (blue). The thickness of the gasket will determine the “lock-in” position of the portafilter handle.
This group gasket is higher quality than the rubberones. Its made from food grade FDA silicone. Unlike regular EPDM rubber gaskets these do not have any smell or taste and they are longer lasting as they will not become hard like rubber ones does.
