A sealing ring is required for Nespresso machines with cartels in the capsule holder. For machines with smooth surface inside the capsule holder no sealing ring is required at all.
The sealing ring is applied to the capsule as follows:
- Close the empty capsule with the lid tightly.
- Role the sealing ring carefully from the smaller end of the capsule towards the lid so that the sealing ring rests on the outer rim of the lid.
- When cleaning the capsule with clear water (no detergent required), the sealing ring does not have to be removed after every use.
