8.5 mm Silicone Group Gasket for E61 Espresso Machine

Silicone group gasket for all E61 espresso machines. This has a thickness of 8.5 mm, which is thicker than standard for coffee machines with E61. If you experience that the portafilter (filter frame) can be tightened further than 90 degrees, it is possible that the fasteners on either the portafilter, or on top of the group are worn. You can then try switching to this group gasket, or if you need a thicker one, choose a group gasket with 9 mm . This is made of silicone, which has a much longer durability than standard rubber.
