Gaggia Cubika Plus 65SH Silicon Boiler Sealing Valve
If water or steam drips or leaks from the group head when the filter holder is not attached, a worn group valve seal may be one of the most common causes.
Common Symptoms This Part May Fix
- Water dripping from the group head without the filter holder attached
- Steam or water leaking from the group head while the machine is heating
- The group valve no longer closing or sealing correctly
- A worn, hardened, deformed, or damaged valve seal
This genuine Gaggia, Saeco and Philips silicone group valve seal, also known as a group valve dome, is used on selected manual coffee machines without a solenoid valve. It works together with the group valve spring to close the water passage and prevent water or steam from escaping through the group head when coffee is not being brewed.
Over time, heat, pressure, limescale, and repeated movement can cause the seal to harden, deform, or lose its sealing ability, resulting in dripping or leaking from the group head.
Trusted by repair technicians and used in professional coffee machine repairs.
Important Information
This group valve seal should be replaced together with the correct spring. The spring used with this seal differs between coffee machine models, so please check the exploded diagram for your machine before ordering.
Replacing only the seal while reusing a worn, weakened, damaged, or incorrect spring may not stop the leak and may prevent the group valve from operating correctly.
We also recommend inspecting and cleaning the valve seat and surrounding area during repair, as limescale or damage may prevent the new seal from seating correctly.

Common Questions
Can this seal stop water or steam dripping from the group head?
In many cases, yes. If water or steam drips from the group head when the filter holder is not attached, the group valve seal may be worn, deformed, or no longer sealing correctly.
Do I need to replace the spring at the same time?
Yes. We recommend replacing the group valve seal together with the correct spring. Different coffee machine models use different springs, and a worn or incorrect spring may prevent the new seal from closing the valve properly.
Is this seal used on machines with a solenoid valve?
This seal is mainly used on selected manual coffee machines without a solenoid valve. Always check the compatibility checker and exploded diagram for your exact model before ordering.
What else should I check during the repair?
Inspect the group valve seat, spring, and surrounding area for limescale, wear, or damage. A dirty or damaged valve seat may still cause leaking after the seal and spring have been replaced.
Will this fit my machine?
Use the compatibility checker and exploded diagrams above to confirm your exact machine model, the correct spring, and the fitting position.
Is this a genuine part?
Yes. This is a genuine replacement group valve seal used in selected Gaggia, Saeco and Philips coffee machines.
