Portafilters
A portafilter has to match the group head it locks into: the diameter, the shape and spacing of the locking lugs, and the depth of the basket all vary between machine lines. Two portafilters with the same nominal diameter are not automatically interchangeable, so we only list a portafilter for a machine when the manufacturer does.
Verified portafilters
10 portafilters part numbers, each listed with the exact model codes the manufacturer’s own page names for it (12 models in total). A part number missing from a model’s row is not proof that it does not fit; only an explicit statement is, and we show those as “Not for”.
