Turbokiller 45 Guard Rear Rubber Cap

Cap 415405 is a rubber end cap closing the Kranzle Turbokiller rotary nozzle guard on the lance side, intended for nozzle size 45. The green colour serves an identification function – it denotes size 45 in the colour coding system used by Kranzle for Turbokiller rotary accessories. The cap seals the rear edge of the guard and protects the space between the guard and the nozzle body from contaminants entering at the inlet side at the lance connection.

Application

The cap is fitted on the rear edge of the Turbokiller size 45 nozzle rubber guard, on the lance side. Closing the rear opening of the guard prevents sand, dirt and abrasive particles from entering the space between the guard and the nozzle body during operation – contamination in this space abrades the nozzle body and can impede free rotation of the rotary head. The rubber material of the cap adapts flexibly at different working angles with the lance.

Replaced when the cap cracks, is lost, or hardens in a way that prevents a tight seal at the rear section of the Turbokiller 45 nozzle guard.

Symptoms – when to replace

• Visible cracking or crumbling of the 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 45 guard.
• Rubber hardened and brittle – loss of elasticity, the cap no longer seals tightly at 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.

How to select the right part

Two parameters must match simultaneously: Turbokiller nozzle size 45 and component type – rear cap (not the main guard). Green is the size 45 code – do not order the cap by colour alone without confirming the nozzle size. Green cap 415405 (size 45) does not fit the Turbokiller 70 nozzle guard – different size, different diameter at the rear edge of the guard.

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

Identify by reference number 415405. Not a substitute for the Turbokiller 70 cap (415406, blue) despite identical function and material.

Compatibility

Rubber rear cap for the Kranzle Turbokiller rotary nozzle guard, size 45, green. Not a substitute for the Turbokiller 70 cap (415406, blue) or the Turbokiller rubber guard (41528). Verify the exact compatibility range by reference number 415405 and Turbokiller nozzle size 45.

What is the relationship between Turbokiller nozzle size and the cap number and colour – how does the coding system work?

Kranzle uses a colour coding system to identify Turbokiller rotary accessory sizes: size 45 = green (415405), size 70 = blue (415406). The reference number unambiguously identifies the size – the colour is a visual shortcut for quick identification when working with several nozzle sets. When ordering, always use the reference number as the reliable basis for selection, not just the colour – the same shade could theoretically appear in other Kranzle accessory lines.
