What is an O-ring and what is it for

An O-ring is a small rubber or silicone seal with a round cross-section, used to seal joints between hoses, pipes and connectors in the water or steam circuit of a coffee machine. It prevents liquid or pressure from escaping at the point where two parts are joined.

Typical signs of wear

Over time it loses elasticity, hardens or cracks due to heat and pressure. This results in water or steam leaking around the joint, dripping under the coffee machine, hissing sounds or a drop in pressure, which also affects the quality of the brewed coffee.

Why timely replacement pays off

A damaged O-ring can no longer keep the joint sealed, which can lead to greater water leakage, damage to nearby components from moisture, or unstable pressure in the system. It is a small part, and replacing it is simple and quickly resolves the leaking problem.

How to choose the right part

When choosing, it is important to check which joint or connector the O-ring is intended for, as dimensions vary between different mounting points. Always check compatibility with your specific model in the product table.
