Black O-Rings for DeLonghi Hydraulic Fittings
DeLonghi bean-to-cup machines use many small push-fit water connections, each with its own O-ring. Heat and scale slowly flatten these seals, and the result is a damp base or a slow loss of pressure. Replacing rings during a service is cheap insurance against a later leak.
A Pack for a Full Service
This bag holds seven black rings with a 3.8 mm bore and a 2.0 mm section. Having seven means you can replace every ring you disturb while the machine is open, rather than reusing tired ones. Keep the leftover rings in a labelled bag with your machine’s manual so they are easy to find next time.
