Cable end ferrules Rittal 4051.732, polypropylene green, 6.3 mm Ø, 18 mm length, pack 500

Rittal 4051.732 cable end ferrules are insulated sleeves made from green polypropylene (PP) designed to terminate stranded conductors. With an outer diameter of 6.3 mm and a length of 18 mm, these ferrules come in a pack of 500 and are intended to prevent wire fraying, improve contact reliability and facilitate secure connections in control cabinets, electrical panels and machinery wiring.

Advantages

These polypropylene cable end ferrules offer consistent insulation and mechanical protection for stripped conductor ends. The uniform dimensions and smooth finish make crimping straightforward and help ensure reliable electrical contact. Supplied in a bulk pack of 500, they are suitable for repeated use in installation and maintenance tasks and help standardize termination quality across multiple cables.

Suitable for

• Termination of stranded conductors in control cabinets and electrical panels
• Wire connections in industrial machinery and automation systems
• Panel building, electrical installation and maintenance work requiring consistent ferrule supply

When it may not be suitable

These ferrules have a polypropylene insulation and defined outer diameter and length; they are intended for stranded conductors that match the ferrule dimensions. They are not intended for solid conductors, conductors requiring higher temperature or chemical resistance than PP provides, or applications that demand a different ferrule size or material.

Key specifications

• Material: Polypropylene (insulation)
• Outer diameter: 6.3 mm
• Length: 18 mm
• Colour: Green
• Quantity per pack: 500 pieces

How to use

Strip the stranded conductor to an appropriate length so that the bare wire fits fully into the metal tube portion of the ferrule. Insert the conductor into the ferrule until the insulation butts against the ferrule collar, then crimp using a suitable insulated ferrule crimping tool sized for the ferrule dimensions. After crimping, inspect the termination to confirm the conductor is secure and the insulation collar is undamaged. Use the crimped ferrule in screw terminals, relays or plug connectors as required.

What to consider before purchase

• Verify that the ferrule outer diameter and length match the conductor cross-section and terminal dimensions you use
• Confirm polypropylene insulation is acceptable for the operating temperature and chemical environment of your installation
• Ensure you have the correct crimping tool for insulated ferrules of this size to achieve reliable terminations

Usage recommendations

Use a calibrated insulated ferrule crimping tool appropriate for the ferrule size, apply consistent crimping pressure, and perform a visual and pull test after crimping to ensure secure, low-resistance connections. Store the pack in a dry, dust-free environment to maintain component cleanliness and ease of handling.
