Nivona coffee machine seal (part number 24374) is a silicone O-ring for pressure hoses. This sealing ring is located on every hose secured with a clamp within the water circuit. If water is leaking from beneath your machine or from a hose connection point, a worn pressure-hose O-ring is the most common cause — and this is the correct replacement part.
Important — verify your model: before ordering, confirm the exact model and version (series, e.g. NICR code) of your machine. You will find this information on the rating label, typically located on the underside of the appliance or behind the water tank. This ensures the part fits your hose and clamp precisely.
When does this part need replacing? (Fault symptoms)
This part typically fails when you notice one or more of the following symptoms:
- Water leaking from beneath the machine or pooling under the appliance outside the drip tray
- Water seeping or dripping from a hose connection point inside the machine
- Weak or slow coffee flow because the connection is not holding the correct pressure
- Hissing sounds during brewing caused by pressure escaping at a leaking connection
A hardened seal can also be identified by the O-ring having lost its elasticity. Seals are subject to high pressure and temperature, causing them to harden and lose their sealing capacity over time — at that point, replacement is necessary.
Compatibility: Which models does this part fit?
This O-ring is a universal pressure-hose sealing part compatible with Nivona fully automatic coffee machines in which hoses within the water circuit are secured with a clamp:
Nivona CafeRomatica (NICR) series
- Nivona CafeRomatica NICR series fully automatic machines — wherever a pressure hose is secured with a clamp
As this is a clamp-hose sealing ring that appears at multiple points in the water circuit, we are happy to confirm an exact match for your machine. If you are unsure, contact our technical support team and quote the exact model from the rating label.
