Distributors for the Chefman CafeMaster Pro
- Size matches the 51mm Chefman CafeMaster Pro group.
- Compatibility inferred from size; not stated by the listing.
- The portafilter's ear/lug geometry appears proprietary to this Chefman group. Even a correctly-sized 51mm third-party bottomless or spouted portafilter may NOT lock into the brew head. Verify the exact ear/lug fit against this specific model before buying any replacement or upgrade portafilter, and prefer sellers with a returns policy.
- 51mm is a thin accessory ecosystem to begin with; many '51mm' listings are cut for DeLonghi/Dedica groups and are not guaranteed to index into a Chefman group even at the same diameter. Confirm the part is fitted to this Chefman, not just to a 51mm DeLonghi, before buying.
- We analyzed manufacturer specs and could not confirm a user-removable shower screen, so screen-swap accessories should be treated as unverified for this machine.
- Skip machine-specific 'bottomless portafilter' purchases until you have physically verified the ear fit; a mismatch here is the most likely and most expensive wrong buy.
- What size to buy
- Buy 50mm or 51mm for the Chefman CafeMaster Pro.
- What to avoid
- Avoid 54mm and 58mm distributors - 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 distributors
Does any 51mm distributor fit the Chefman CafeMaster Pro?
No. The nominal size is only the first check. Model-specific locking geometry, basket depth, mounting pattern, or clearance may also matter. The portafilter's ear/lug geometry appears proprietary to this Chefman group. Even a correctly-sized 51mm third-party bottomless or spouted portafilter may NOT lock into the brew head. Verify the exact ear/lug fit against this specific model before buying any replacement or upgrade portafilter, and prefer sellers with a returns policy.
Is a distributor the first upgrade to buy?
Not automatically. The Chefman CafeMaster Pro's stored upgrade order starts with tamper; fix grinder, basket, dose, or maintenance issues before adding optional tools.
