Sealing ring for gear rod

What this sealing ring does

The sealing ring for gear rod is a small gasket fitted around the toothed rod mechanism inside a coffee machine's brewing or dosing unit. It prevents water, steam or ground coffee residue from leaking along the rod as it moves, keeping the surrounding parts dry and protected from pressure loss.

Signs it needs replacing

Over time, this ring can lose its elasticity due to heat and constant friction, leading to visible leaks, reduced pressure, or a looser feel around the gear rod. Cracks, flattening or a hardened texture are typical signs that the seal is no longer doing its job properly.

Choosing the right one

Before ordering, check the compatibility table listed with this product to confirm it matches your specific coffee machine model.
