Stop ring 3 mm

What this small part does

The Stop Ring 3 mm is a retaining ring (circlip) used inside coffee machines to secure a shaft, pin, or component in place, preventing unwanted axial movement of connected parts during operation.

Signs it needs replacing

Over time, retaining rings can lose tension, become deformed, or corrode, which may cause the secured component to shift, rattle, or fail to hold its position properly. A worn or damaged stop ring can lead to misalignment or looseness in the assembly it was meant to secure.

Choosing the right part

Before ordering, check the compatibility table by the product to confirm this stop ring matches your specific coffee machine model and application.
