O-ring silicone 3.3x2.0 - 10pcs.

What is an O-ring and what is it for

An O-ring is a small circular seal used in a coffee machine in dozens of places – in the hydraulic circuit, on pistons, valves, nozzles, hose connections or in the steam wand. Its job is to seal the joint between two parts so that water, steam or pressure cannot escape through it.

Signs of wear

Over time it loses elasticity, hardens or cracks. This shows up as water or steam leaking around the joint, dripping under the machine, a drop in pressure when brewing coffee, or hissing and humming when steam flows through. Sometimes wear even affects the taste of the coffee, when the leak alters the extraction pressure.

Why replace this part in time

A damaged O-ring may look like a minor detail, but a long-term leak of water or steam can damage surrounding parts and reduce the coffee machine's performance. Replacement is a quick and cheap fix that prevents bigger problems.

How to choose the right one

• The key factor is size – the diameter and thickness of the ring, or the material stated with the product.
• Check the compatibility table on the product page according to your coffee machine's model.
• If ordering several pieces, it's a good idea to keep spare O-rings in stock, as this is a part that wears out regularly.
