Description
Replacement group-head seal for De’Longhi Dedica and La Specialista espresso machines, including selected La Specialista Maestro models.
If water is leaking around the portafilter while brewing, the portafilter no longer locks in firmly, or brew pressure is escaping at the group head, a worn seal is a common cause. Replacing the gasket restores a snug seal between the portafilter and group head.
