What size to buy
Buy 58mm. Tampers and distributors can go 57mm (1mm under); baskets, shower screens and portafilters must be an exact 58mm match.
What to avoid
51mm and 54mm parts will not seat or seal in a 58mm group - there is no adapter.

How 58mm compares

51mm Budget entry
De'Longhi Dedica
De'Longhi Dedica
Fits: Basic bottomless portafilters and a few baskets.
Thinnest aftermarket - keep it simple.
54mm Breville standard
Breville Bambino Plus
Breville Bambino Plus · Breville Bambino · Breville Barista Express
Fits: Bottomless PFs, single-wall & precision baskets, tampers (53mm), distributors, shower screens.
Deep, beginner-friendly range.
58mm Commercial standard
Gaggia Classic Evo Pro
Gaggia Classic Evo Pro
Fits: VST/IMS precision baskets, bottomless PFs, tampers (58mm), PID & OPV mods.
Widest selection - the upgrade engine.
The one rule: match the size to your group head. Baskets, screens and portafilters must be exact; tampers and distributors go 1mm under (a 53mm tamper for a 54mm Breville). The wrong size will not seat or seal.

Compatibility here is inferred from portafilter size, not hands-on testing. Always confirm the listed size against your machine's group before buying - see our methodology and size chart.
