Lance tube 500 mm 1/4"

Lance tube 123851 has a length of 500 mm and a 1/4" thread, making it a medium-length working section between the gun, handle, or additional accessory component. During replacement, the key factors are thread condition, tube straightness, and compatibility of the ends with the current lance configuration.

APPLICATION

The tube is used as part of the working accessories in Kranzle pressure washers. It transfers pressurised water from the gun or handle side toward the working tip, nozzle, or another component mounted in the lance system.

The 500 mm length provides greater reach than short tubes, but it is not as long as 600 mm variants. This matters when maintaining comfortable handling of the accessories, especially where the operator needs a stable, rigid extension without excessive distance from the working point.

SYMPTOMS – WHEN REPLACEMENT IS RECOMMENDED

Replacing the lance tube may be necessary when the following issues occur:

• damaged, seized, or stripped 1/4" thread,
• leakage at the connection with the gun, handle, or working tip,
• clearly bent tube after impact,
• corrosion in the thread area or near the connection end,
• inability to tighten the cooperating component correctly,
• incompatible length compared with the previous accessory setup.

Minor signs of use on the surface of the steel tube are not a reason for replacement. What matters are defects affecting tightness, thread condition, axial alignment of the accessories, or stable tightening of the connection.

HOW TO SELECT THE CORRECT PART

Selection should be based on the 500 mm length, 1/4" thread, and reference number 123851. Before installation, compare it with the removed tube: total length, end type, thread condition, and connection method with the remaining lance components.

If the previous setup was comfortable in use, it is best to keep the same length. Changing from a 500 mm tube to a shorter or longer version may affect reach, accessory balance, and nozzle position relative to the cleaned surface.

COMPATIBILITY

Lance tube 123851 has a length of 500 mm and a 1/4" thread. It is used as part of Kranzle pressure washer accessories in systems requiring a steel working tube with these specifications.

[faq]

Is corrosion near the thread more important than scratches on the tube?|Yes. Scratches on the outer surface usually do not affect operation. Corrosion near the thread may make tightening difficult, reduce connection tightness, or accelerate wear of the cooperating component.

What should be done if the new tube screws in only partially?|Do not force tightening. Check whether an old seal remains in the socket, whether the thread is contaminated, and whether the cooperating component uses the correct connection standard.

Does a slightly bent steel tube interfere with operation?|It depends on the degree of bending. If the tube can still be mounted leak-free and does not affect the positioning of the working tip, the issue may only be cosmetic. Replacement makes sense when the bend interferes with work or places stress on the connections.

Why is the length important for this tube, not only the 1/4" thread?|The same thread may be used in tubes of different lengths. The 500 mm length affects reach, handling comfort, and the position of the working tip, so it should match the previous accessory configuration.
