Rotating Hose End DN8 M22x1.5

End fitting 40324 is a rotating end for a high-pressure hose with a nominal diameter of DN8 (NW8) and M22x1.5 thread. Rotation relative to the hose eliminates torsional stress created during operation – the hose does not wind around its own axis and does not stiffen during sudden changes of direction. The internal spindle allows free rotation while maintaining a seal under working pressure.

Application

The end fitting is mounted at the end of a DN8 high-pressure hose – on the connection side to the gun, lance or other accessory of the Kranzle pressure washer. The M22x1.5 thread is the standard connection used in Kranzle accessories. The free rotation of the end fitting operates independently of the operator's position – the hose remains relaxed even during intensive work with a wide variation in angle.

Used when repairing a hose with a damaged end fitting, replacing the end with a rotating version, or reconditioning a hose assembly after mechanical damage to the connector.

Symptoms – when to replace

• Water leak at the connection point between the end fitting and the hose – under working pressure or immediately after it drops.
• Seized or noticeably restricted rotation of the end fitting – the hose starts to twist during normal operation, which did not occur previously.
• Visible damage to the M22x1.5 thread – crushed threads, difficulty screwing on accessories, or noticeable play after closing the connection.
• Cracking or splitting of the crimping sleeve at the connection point with the hose – the hose slides out or rotates together with the accessory instead of the end fitting rotating independently.
• Corrosion or pitting on the rotating spindle leading to leaks at full pressure.

How to select the right part

The basic selection parameters are three values simultaneously: nominal hose diameter DN8 (NW8), M22x1.5 thread, and end fitting type – rotating. Changing any one of these parameters means a different part.

Most common ordering mistakes:

• DN8 vs DN10 – different hoses with different end fittings, not interchangeable. Measure the outer diameter of the hose or check its marking before ordering.
• Rotating vs fixed – a fixed end fitting (without a rotation mechanism) is a separate part. If you are replacing a damaged end fitting, make sure the original was rotating – rotation can be felt even on a damaged part.
• Thread configuration – M22x1.5 thread can be male or female depending on the mounting side. Before ordering, confirm that 40324 matches the connection side of your accessory.
• Identification by reference number 40324 is more reliable than by dimensions alone – use it as verification, not the only basis for selection.

Compatibility

End fitting for DN8 (NW8) high-pressure hoses used in Kranzle pressure washers with M22x1.5 connections. Verify the exact compatibility range by reference number 40324 and by comparison with the removed part.

What is the difference between a rotating and a fixed end fitting, and when does this difference have practical significance?|A fixed end fitting transfers twisting directly to the hose – during intensive work with a wide variation in direction the hose stiffens, wears out faster and becomes harder to manoeuvre. A rotating end fitting separates the movement of the hose from the movement of the accessory – the hose remains relaxed. In workshop and service work, where the operator frequently changes position, the difference becomes noticeable after a short period of use.

How to check whether the rotation mechanism of the end fitting is working before removing the hose?|With the accessory connected, grip the end fitting just behind the gun or lance and try to rotate it – if the mechanism is working, the rotation should be smooth and light. Resistance, clicking or seizing indicates a seized or worn spindle. Hard water deposits block the mechanism from inside – a brief flush sometimes helps, but with visible spindle corrosion replacement is the safer option.

M22x1.5 thread is also found in automotive connectors – are these parts interchangeable?|M22x1.5 thread appears in several industries, but seal geometry, thread length and working pressure can differ. Do not use parts from automotive installations as replacements in the pressure circuit of a washer – the risk of leaks or damage at the washer's working pressure is real. Use only parts intended for high-pressure hoses.
