This will fit a number of different manufactures models of machines - most that have the E-61 or E-61 style group head (except the ECM Giotto, Expobar and Vibiemme groups, which are different) - as well as almost all models of Faema machines (with the only exception being the domestic models, such as the Faema Family). Assembly is required.
The spouts can be challenging for some to install. Many times the thickness of chrome on either the spout or the threads on the portafilter (or both), varies, and getting the spout to thread on may require more than one attempt. If it will not install far enough, a wrench and a very strong twist should position it over. In some extreme cases the only option is to clamp the spout in a bench vice and crank the handle. If it threads on too far PTFE plumbers tape or a gasket may be required.
The ears on this portafilter measure about 27.3 mm long, 6.5 mm thick, and 7.7 mm wide.
Isomac and Giotto users! As the Isomac and Giotto use an E61 "style" group and the casting is slightly different than a traditional Faema E61, this may not work for you. We do not currently carry portafilters specifically for the Isomac. In any event ALWAYS MEASURE YOUR EARS!
