Turbokiller 70 Guard Rear Rubber Cap

Cap 415406 is a rubber end cap closing the Kranzle Turbokiller rotary nozzle guard on the lance side – the rear section of the guard through which the nozzle-to-lance connection passes. The blue colour serves an identification function – it denotes nozzle size 70 in the colour coding system used by Kranzle for rotary accessories. The cap seals the rear edge of the guard and protects the inlet area from contaminants entering between the guard and the nozzle body.

Application

The cap is fitted on the rear edge of the Turbokiller nozzle rubber guard, on the lance side. Closing the rear opening of the guard prevents dirt, sand and abrasive particles from entering the space between the guard and the nozzle body during operation – contamination in this space could abrade the nozzle body surface and impede free rotation of the rotary head. The rubber material of the cap allows flexible adaptation to the lance connection at varying working angles.

Replaced when the cap cracks, is lost, or hardens in a way that prevents a tight seal at the rear section of the guard.

Symptoms – when to replace

• Visible cracking or crumbling of the cap rubber – the rear edge of the guard is no longer sealed, and contaminants enter the space between the guard and the nozzle body.
• Cap slides or falls off during operation – loss of secure seating on the rear edge of the Turbokiller guard.
• Rubber hardened and brittle – loss of elasticity, the cap no longer adapts tightly to the lance connection when the working angle changes.
• Cap missing entirely – the space between the guard and the nozzle body is open on the lance side, accelerating contamination of the rotary mechanism.

How to select the right part

Two parameters must match simultaneously: Turbokiller nozzle size 70 and component type – rear cap (not the main guard 41528). Blue is the size 70 code – for other Turbokiller sizes the cap colours may differ. Before ordering, confirm the nozzle size and the colour of the original.

When replacing the cap, also assess the condition of the main guard 41528 – if the rear edge of the guard is deformed or cracked, a new cap will not seal this area correctly without replacing the guard.

Compatibility

Rubber rear cap for the Kranzle Turbokiller rotary nozzle guard, size 70, blue. Not a substitute for the Turbokiller rubber guard (41528) or guards for other Kranzle nozzle types. Verify the exact compatibility range by reference number 415406 and Turbokiller nozzle size 70.

FAQ

Why is the rear section of the Turbokiller guard closed with a separate cap rather than being a single continuous component with the guard?|The guard and cap as two separate components allow independent replacement of each – when only the cap is damaged, there is no need to replace the complete main guard, and vice versa. The rear closure as a separate component also makes guard installation easier, as the flexible rubber cap can be adjusted after the guard has been fitted to the nozzle body.

What does the blue colour of cap 415406 indicate, and how to identify size 70?|Blue is the size 70 code in the Kranzle Turbokiller accessory identification system. Different Turbokiller nozzle sizes are identified by different guard component colours, allowing quick size identification without reading text during operation. Size 70 refers to the nozzle parameters – when ordering the cap, always specify size 70 or reference number 415406, not the colour alone as the only selection criterion.
