Ermeto Tube – Complete

Tube 410411 is a complete hydraulic line in the Ermeto system, intended for the Kranzle Profi-Jet pressure washer in the AP variant. Complete means the tube has factory-fitted Ermeto connectors on both ends – ready for installation without additional swaging or machining. The metal Ermeto tube carries water under the washer's working pressure between components of the hydraulic circuit, where a flexible hose is not used due to installation geometry or space constraints.

Application

The tube is mounted in the hydraulic circuit of the washer, connecting two points of the installation through a fixed, rigid pipe connection.

Replaced when the tube is mechanically damaged (bent, cracked, corroded), when the Ermeto fitting leaks on the tube side, or when there is a leak at the connection with other components of the hydraulic circuit.

Symptoms – when to replace

• Water leak at the Ermeto fitting under working pressure – worn or damaged ferrule or fitting seat.
• Visible mechanical damage to the tube – bending, flattening or cracking of the metal tube body.
• External corrosion or pitting on the tube – particularly in environments with aggressive cleaning agents or where the tube coating is damaged.
• Leak that recurs cyclically after tightening the fitting – indicates a damaged tapered seat in the fitting or a deformed ferrule that cannot be permanently sealed by tightening alone.

How to select the right part

Identify by reference number 410411. Before ordering, confirm on the removed tube: the total length between fittings, tube diameter, the type of Ermeto fittings on both ends (straight, angled, size) and any configuration with different fittings on each end.

Complete tube 410411 is a factory component with a precisely bent profile and matched fittings – do not substitute it with a length of industrial tubing of the same diameter without confirming identical geometry and fitting configuration. The wrong length or bend angle will prevent installation in the space designed for this tube.

When replacing the tube, assess the condition of the fittings at the connection points at the same time – a damaged seat in the pump or valve block connection will prevent a tight fit even with a new tube.

Compatibility

Complete Ermeto line for the hydraulic circuit of the Kranzle Profi-Jet pressure washer. Verify the exact compatibility range by reference number 410411 and the Profi-Jet model.

FAQ

What does "complete" mean for an Ermeto tube, and how does it differ from raw hydraulic tubing?|A complete Ermeto tube is a ready-made component with factory-fitted connectors on both ends – precisely cut to length and, if required, bent to a profile matched to the installation space in the washer. Raw hydraulic tubing is a length without connectors, requiring Ermeto ferrules to be swaged using a specialist tool and cutting to the correct length. When replacing a damaged tube in the Profi-Jet washer, complete component 410411 is the only reliable option for retaining the original geometry and fitting configuration.

Why is a rigid Ermeto tube used in this part of the hydraulic circuit instead of a flexible hose?|Rigid Ermeto hydraulic tubes are used where a flexible hose does not fit due to restricted installation space, where a precise line routing profile is required, or where vibration and working pressure would lead to flexible hose fatigue in a short time. In the internal installations of pressure washers, Ermeto tubes provide a more durable and predictable connection than a hose at locations with fixed geometry and an unchanging line route.

How to check the tightness of a newly installed Ermeto tube before fully starting the washer?|After installation, start the washer at low pressure (open the gun and allow the pump to run unloaded) and observe both ends of the tube for several seconds. If there is no leak at low pressure, gradually increase the load to full working pressure. Ermeto fittings may require slight bedding in on first start-up – a small leak at the first pressure test sometimes stops after the ferrule beds in. If the leak persists at full pressure, switch off the washer and check the Ermeto nut tightening torque.
