The 8mm Orange silicone group gasket by Caffewerks US fits E61 (58mm) brew group head espresso machines. These hold up very well in brew groups and remain soft and leak-free longer than rubber. The softer silicone makes engaging the portafilter easier thus less effort and less strain on your wrists.
