Fit note: Check the fin count and blade base against your original BN401 blade before ordering.
Accessories for NutriBullet Pro 900 NB9-0801

Best for: Owners whose cups and blade are both due for replacement.
Fit note: The listing is for 600W and 900W systems. Check the cup threads, blade base, and gasket against your Pro 900.
How to Choose the Right Accessory
Start with the problem you actually have. A replacement lid or seal makes sense when the blender still runs but leaks. Extra cups help when you make drinks often. A new blade is the right choice when the old blade is worn.
- Check the size first.
- Make sure it fits your exact model.
- Do not buy a full accessory set if you only need one piece.
- Skip accessories that block lids, cups, blades, or moving parts.
- Start with the accessory that fixes your biggest daily problem.
