This compatible replacement O-ring is mainly used to seal PTFE pipe fittings and connections in Delonghi coffee machines. Depending on the machine model, the same O-ring may also be used in other internal fittings and connections. Over time, heat, pressure, limescale, and age can cause O-rings to harden, flatten, or lose their sealing ability, resulting in leaks.

Common Questions
Can this O-ring fix a leaking PTFE pipe connection?
Yes. If water or steam is escaping around a PTFE pipe fitting, a worn, flattened, or damaged O-ring may be preventing the connection from sealing correctly.
Is this O-ring only used on PTFE pipes?
No. PTFE pipe connections are its main application in many compatible Delonghi coffee machines, but the same O-ring may also be used in other internal fittings and connections depending on the model.
Should I replace this O-ring during repair?
Yes. If the original O-ring is damaged, flattened, brittle, or no longer seals correctly, we recommend replacing it. As O-rings are wear items, we also generally recommend replacement every 4 years during routine servicing, even if there are no obvious signs of damage. Reusing an old seal can sometimes cause leaks after reassembly.
