VarioJet Nozzle Guard

Guard 411551 is a protective component for the VarioJet nozzle of the Kranzle pressure washer. It protects the internal spray angle adjustment mechanism from mechanical damage, contamination and direct contact with cleaned surfaces. The VarioJet nozzle allows continuous adjustment of the spray angle without replacing the nozzle – the guard stabilises and protects this mechanism during operation.

Application

The guard is mounted on the outer part of the VarioJet nozzle, covering its front or side section where the adjustment mechanism is located. When working in demanding conditions – close to surfaces, cleaning edges or corners – the guard absorbs impacts and scrapes against the substrate instead of the nozzle body or adjustment mechanism. Without the guard, the nozzle body and adjustment mechanism are directly exposed to mechanical damage.

Replaced when the guard is cracked, shattered or deformed in a way that prevents it from seating correctly on the VarioJet nozzle.

Symptoms – when to replace

• Visible cracking or shattering of the guard – plastic cracked from impacts or discoloured and brittle after prolonged UV and detergent exposure.
• The guard does not sit securely on the VarioJet nozzle – noticeable play or falling off during use, indicating damaged retention features.
• Deformation of the guard causing friction against the adjustment mechanism – rotation of the adjustment ring is difficult or impossible despite an otherwise intact nozzle.
• Guard missing entirely – VarioJet nozzle in use without protection, risking damage to the adjustment mechanism at the first contact with a hard surface.

How to select the right part

Identify by reference number 411551. Guard 411551 is intended exclusively for the Kranzle VarioJet nozzle – it does not fit other nozzle types from this brand (Turbokiller, Dirtkiller, flat fan nozzles). Before ordering, confirm you have a VarioJet nozzle and not another type of adjustable nozzle.

When purchasing the guard alone, check the condition of the VarioJet nozzle adjustment mechanism – if the guard was damaged by a drop or impact, also assess the condition of the adjustment ring and nozzle body before fitting the new guard.

Compatibility

Guard for the VarioJet nozzle of Kranzle pressure washers. Verify the exact compatibility range by reference number 411551 and the VarioJet nozzle type.

[faq]

Can guard 411551 be purchased separately, or only together with the complete VarioJet nozzle?|The guard is available as a separate service part, without the need to purchase a complete VarioJet nozzle. This is significant because the VarioJet nozzle as an adjustment mechanism is a considerably more expensive component than the guard alone – when only the guard is damaged with the nozzle mechanism intact, replacing the guard on its own is the correct and economical solution.

How does the VarioJet nozzle differ from other Kranzle nozzles, and why does it have a separate guard?|VarioJet is a nozzle with a continuously adjustable spray angle – the operator changes the spray angle by rotating the nozzle body, without replacing the entire component. This adjustment mechanism is more complex than in fixed-angle nozzles and contains moving parts that require protection from contamination and impacts.
