DeLonghi Steam Boiler End Connector + O-Ring Kit
Complete Steam Connection Repair Kit – Lattissima / Dinamica / Eletta / Primadonna / La Specialista
Restore full steam pressure and eliminate internal leaks with this DeLonghi Steam Connector & O-Ring Repair Kit, combining both critical sealing components used in the boiler-to-steam system.
This kit includes:
- 🔩 Steam Connector: 5513216741
- ⚫ Black O-Ring: 5313217701
Together, these parts restore a tight, high-pressure steam seal between the boiler/vaporizer and steam pipe system in DeLonghi automatic coffee machines.
If your machine is experiencing steam leaks, weak froth, hissing noises, or internal moisture, this is one of the most effective repair kits available.
🔧 Product Overview
The steam connector and O-ring work together as a high-pressure sealing interface in the steam circuit.
They are exposed to:
- Continuous high-temperature steam
- Pressure cycling during every milk frothing cycle
- Limescale buildup (especially in Australian water conditions)
- Thermal expansion and contraction
Over time, the O-ring hardens and the connector loses sealing precision, resulting in steam leaks and pressure loss.
