Delonghi O-Ring 02025 Black Silicone
If a mechanics valve, milk-carafe coupling, or frother connection is leaking or no longer sealing correctly, a worn 02025 black silicone O-ring may be one of the possible causes.
Common Symptoms This Part May Fix
- Water or steam leaking from the mechanics valve area
- Poor sealing around the milk-carafe coupling
- Air entering through a worn coupling or frother seal
- A flattened, hardened, split, or damaged O-ring
This genuine Delonghi 02025 black silicone O-ring is mainly used inside the mechanics valve on selected Delonghi coffee machines. It is also used as the smaller O-ring on Delonghi carafe coupling 5513214821 (DELONGHI-1-1282) and may be fitted to selected frother assemblies.
The exact fitting position depends on the Delonghi coffee machine model. Over time, heat, pressure, movement, and age can cause the O-ring to harden, flatten, or lose its sealing ability, resulting in leaks or poor performance.
Trusted by repair technicians and used in professional coffee machine repairs.
