Hose SCHAERER Spare Parts 3370067760

A hose of this type carries water, steam or cleaning solutions between fixed pipework and moving parts inside professional coffee machines. The inner layer is made from PFA, a fluoropolymer that resists heat, pressure and chemical attack, so the hose remains flexible and leak-free even when the machine cycles between cold water and live steam. An outer braid or jacket protects the PFA tube from abrasion and kinking, extending the working life in a busy café or restaurant environment.

The operator connects one end to the machine's water inlet or steam outlet, and the other to the corresponding fitting on the boiler, group head or steam wand. Once secured with the correct clamps or unions, the hose flexes as the machine expands and contracts during heating and cooling, preventing stress fractures at the joints. Because the hose is transparent or semi-transparent, staff can visually check for scale, discolouration or trapped air bubbles without dismantling the line.

Cleaning follows from the materials: the PFA lining can be flushed with descaling agents and sanitising solutions without absorbing odours or flavours. After flushing, the hose is left to dry in place or hung vertically to drain completely, reducing the risk of bacterial growth in residual water.

This hose is a direct replacement for SCHAERER coffee equipment. It is sized 4/6, indicating the internal and external diameters that match the manufacturer's original fittings, ensuring a secure, leak-proof connection without adapters or modifications.

The product is listed in the SCHAERER spare-parts catalogue under coffee-machine components.
