## Summary description

Rittal 4051.726 cable ferrules made of polypropylene (PP) in grey. Each ferrule measures 18 mm in length with a 4.2 mm outer diameter. Supplied in a pack of 500, these ferrules provide insulated termination for stranded conductors, improving connection reliability and preventing fraying in control cabinets, switchgear and general electrical installations.

## Long description

Rittal polypropylene cable ferrules in grey provide insulated terminations for stranded conductors. Each ferrule is 18 mm long with an outer diameter of 4.2 mm and is supplied in a pack of 500. These ferrules help prevent conductor fraying, improve the reliability of screw and clamp connections, and are intended for use in control cabinets, switchgear and general electrical installations where secure, repeatable terminations are required.
Advantages
The polypropylene material offers chemical resistance and electrical insulation while remaining lightweight and dimensionally stable. A consistent 18 mm length and 4.2 mm outer diameter ensure uniform insertion depth and fit for compatible connection points. Supplied in a bulk pack of 500, they reduce handling time and provide a ready supply for repetitive wiring tasks. The insulated collar protects conductors from damage and helps maintain secure clamping pressure in screw terminals.
Suitable for
 Insulating and terminating stranded conductors in control cabinets and switchgear
 Routine electrical panel wiring and maintenance
 Industrial and commercial electrical installations requiring repeatable terminations
 Environments where a high quantity of terminations are performed and bulk packaging is preferred
When it may not be suitable
These polypropylene ferrules are designed for standard stranded conductor termination; they may not be suitable for solid conductors, very fine strand bundles outside the matching conductor cross-section, or applications requiring high-temperature or flame-retardant materials. For installations that demand specific regulatory approvals, halogen-free properties, or higher thermal resistance, select a ferrule material and specification that meet those requirements.
Key specifications
 Material: polypropylene (PP)
 Colour: grey
 Length: 18 mm
 Outer diameter: 4.2 mm
 Packaging: pack of 500 pieces
 Function: insulated termination for stranded conductors
How to use
Strip the conductor to the recommended length for the ferrule, insert the stranded conductor fully into the ferrule barrel so that no stray strands protrude, and crimp using an appropriate ferrule crimping tool sized for the conductor cross-section. After crimping, insert the ferrule into the terminal and fasten the screw or clamp to the manufacturer’s torque specification. Store unused ferrules in a dry place to avoid contamination or deformation prior to use.
What to consider before purchase
 Ensure the ferrule dimensions and material are compatible with the conductor cross-section and terminal type
 Confirm that polypropylene meets the environmental and regulatory requirements of your installation
 Check that bulk packaging quantity (500 pieces) fits your project needs and storage capacity
Usage recommendations
Use a dedicated ferrule crimping tool sized for the actual conductor cross-section to achieve consistent crimps and reliable electrical connections. Verify torque settings on terminals after installation and keep ferrules in original packaging until use to prevent contamination.
