What the part does
The milk frother or steam wand coupling connects the milk container or steam nozzle to the body of the coffee machine, ensuring that steam or a mixture of steam and air needed for frothing milk flows through it. It is a mechanical connecting element through which pressure and movement are transferred between the fixed part of the machine and the movable attachment.
When the part stops doing its job
- Milk does not froth or the foam is thin and unstable
- The connection between the container and the machine is loose, wobbles, or holds poorly
- Steam escapes outside the correct path and an unusual hissing can be heard
- The frother is difficult to attach or does not stay in place at all
Why timely replacement pays off
A worn or cracked coupling causes steam leakage, reduces frothing efficiency, and can lead to the milk system failing completely. Timely replacement prevents further damage to the surrounding parts of the steam wand.
How to choose the right part
Couplings vary in shape and mounting method depending on the specific coffee machine model, so be sure to check compatibility in the product table before purchasing.
