Preformed transparent suction hose SCHAERER Spare Parts 3370072642

A preformed suction hose carries liquids under negative pressure from a tap, hopper or tank to the pump in professional beverage equipment. The hose is shaped to follow the machine's internal routing without kinking, so the flow stays steady and the pump does not cavitate. Transparent silicone lets the operator see the liquid moving, which confirms the line is clear and helps spot blockages or air locks before they stop the machine.

The hose is fitted by sliding the 16 mm end onto the smaller connection and the 22 mm end onto the larger one, then securing each joint with a clamp or clip. Once installed, the hose runs whenever the pump is switched on, drawing liquid from the source and delivering it to the next stage—grinder, boiler or dispenser. Because the hose is under suction, any leak will draw air in rather than let liquid out, so a tight seal is critical to keep the system primed and the flow consistent.

Made of food-grade silicone, the hose withstands repeated hot-water cleaning and the acids and oils found in coffee, milk and syrups. The material stays flexible across the temperature range of a working machine, so it does not harden or crack when the equipment cycles between cold rinse and hot brew. Silicone is also non-stick, which reduces scale build-up inside the hose and makes it easier to flush clean.

Cleaning follows the same programme as the rest of the machine: a rinse cycle with hot water and detergent, then a clear-water flush. The transparent wall lets the operator check that the inside is free of residue without disconnecting the hose. If the hose is removed for deeper cleaning, it can be washed in a sink or dishwasher, then air-dried before refitting.

This hose is a direct replacement for the preformed suction line in SCHAERER beverage equipment. It fits the specified diameters and contours of the original part, so it drops into place without modification.
