Ensure proper steam pressure and leak-free operation with the Delonghi Espresso Machine Steam Nozzle O-Ring 535693. This small but essential sealing component prevents steam and water leakage from the nozzle, ensuring consistent frothing performance. A worn O-ring can reduce steam efficiency and affect milk frothing quality.

Made from high-grade heat-resistant rubber, this O-ring provides excellent sealing performance under high pressure and temperature conditions. It maintains flexibility and durability even with frequent steam usage.

Installation / Replacement Instructions:
1. Turn off the espresso machine and unplug it.
2. Allow the steam system to cool completely.
3. Remove the steam nozzle assembly carefully.
4. Take out the old O-ring from the nozzle groove.
5. Install the new 535693 O-ring securely in place.
6. Reassemble the nozzle and test steam output for leaks.
