Cimbali group inlet piping

What is the brewing unit inlet tube

This is a rigid or shaped tube that carries hot water from the boiler or pump to the coffee machine's brewing unit. It ensures a smooth and tight flow of water under pressure at the moment of espresso preparation, so it must be perfectly sealed and unobstructed.

When the part stops doing its job

• Water leaking or dripping at the point where the tube connects to the brewing unit
• Fluctuating pressure or uneven water flow during extraction
• Change in coffee taste caused by limescale deposits inside the tube
• Hissing, bubbling, or other unusual sounds during brewing

Why you shouldn't put off the replacement

A damaged or clogged tube reduces the brewing unit's performance, causes uneven extraction, and can lead to further damage to surrounding components if water leaks over a long period. Timely replacement prevents unnecessary breakdowns and keeps coffee quality consistent.

How to choose the right part

Since the shape and dimensions of the tube vary depending on the specific brewing unit model, always check compatibility in the product table before purchasing.
