What is a retaining ring

A retaining ring (also called a circlip or snap ring) is a small metal component that fits into a groove on a shaft or in a bore and serves to axially secure other parts in place. In a coffee machine, it holds parts such as bearings, pins, pistons or the boiler so they cannot shift or come loose during normal operation.

Signs of wear or damage

• A loose or corroded ring loses its tension and can no longer hold sufficient pressure in the groove
• The part it was securing starts to move, rattle or fall out
• Water or steam leakage may appear at the point where the ring was securing another part's seal

When it's time for a replacement

A damaged or deformed retaining ring no longer reliably secures the part, which can lead to it shifting, wearing down neighbouring components, or even causing a bigger fault in the coffee machine. Replacement is a simple and cheap way to prevent larger problems.

How to choose the right part

When choosing, the exact diameter and shape of the ring are important, as they must match the specific mounting location. Check the compatibility table on the product page to select the correct size for your coffee machine.
