Gaskets for the De'Longhi La Specialista Arte Evo
- Size matches the 51mm De'Longhi La Specialista Arte Evo group.
- Listing names a DeLonghi model or machine it claims to fit.
- A De'Longhi replacement filter assembly for EC9255M shows a 51mm La Specialista-style three-lug portafilter. Treat whole portafilter swaps as La Specialista-family fitment, not generic Dedica/Stilosa/ECP 51mm fitment.
- Aftermarket 51mm 'La Specialista' bottomless portafilters often list older models (e.g. EC9335/9155/9355/9665). Prefer listings that explicitly confirm EC9255 / Arte Evo, or buy only with a return path.
- Precision baskets remain the safer extraction upgrade: a 51mm precision basket drops into the stock portafilter and does not depend on matching the replacement-portafilter ear body.
- The grinder is built in, so external single-dose grinder accessories (dosing cups sized to a separate grinder) are not part of this machine's workflow.
- What size to buy
- Buy 51mm for the De'Longhi La Specialista Arte Evo.
- What to avoid
- Avoid 54mm and 58mm gaskets - they will not fit the 51mm group.
- If you own another machine
- Own a Breville Bambino? Use the 54mm page instead - these 51mm parts will not fit it.

Before buying gaskets
Does any 51mm gasket fit the De'Longhi La Specialista Arte Evo?
No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. A De'Longhi replacement filter assembly for EC9255M shows a 51mm La Specialista-style three-lug portafilter. Treat whole portafilter swaps as La Specialista-family fitment, not generic Dedica/Stilosa/ECP 51mm fitment.
Is a gasket the first upgrade to buy?
Not automatically. The De'Longhi La Specialista Arte Evo's stored upgrade order starts with wdt tool; fix grinder, basket, dose, or maintenance issues before adding optional tools.
