Milk container hose for Siemens EQ.700/EQ.9 coffee machines

What is the milk frother hose

This hose carries milk from the container or bag to the frothing unit of the coffee machine, where it mixes with air and steam or pressure to create frothed milk for cappuccino or latte. It is the connecting element between the milk container and the frother nozzle.

Signs of wear

• Milk is drawn in slowly or not at all, foam is thin or missing
• Milk or water leaks around the hose or at its connection
• The hose is cracked, hardened or deformed and loses tightness
• Residue appears in the milk or in the frothed structure

Why replace this part in time

An old or damaged hose can cause incorrect milk dosing, poorer foam quality and, in the worst case, a hygiene issue, as milk residue settles more easily in damaged material and bacteria can form. Timely replacement keeps the frother running reliably.

How to choose the right hose

Hoses differ in length, diameter and the shape of the end fittings depending on the specific coffee machine model, so check the compatibility table on the product page before purchasing.
