Why Choose the Partex CEF25016F-K 25 mm² Black Insulated Cord End Ferrule?
The Partex CEF25016F-K is a professional-grade single insulated cord end ferrule designed to provide secure and consistent electrical terminations for flexible stranded copper conductors. Featuring a 25 mm² conductor capacity, a 16 mm metal barrel length and distinctive black insulation, this bootlace ferrule is ideal for industrial electrical installations, power distribution equipment and control panel wiring.
As part of the Partex CEF insulated cord end ferrule range, the CEF25016F-K consolidates individual conductor strands within a conductive metal sleeve. This helps prevent loose strands, fraying and conductor damage during termination, while providing a neat and repeatable connection when used with compatible electrical terminal blocks.
Manufactured with a tin-plated high-conductivity copper barrel and a Polyamide 66 insulated collar, the ferrule combines dependable electrical contact with durable conductor entry protection. Its black French-type colour coding identifies the 25 mm² conductor size, while the pack of 1000 provides a practical solution for high-volume panel building, electrical installation and industrial equipment manufacturing.

Reliable 25 mm² Cable Termination for Industrial Power and Control Wiring
Flexible stranded copper conductors are widely used in industrial electrical installations, power distribution equipment and machinery because they provide flexibility during cable routing and assembly. However, individual strands can spread or become damaged when connected directly to certain electrical terminals. The Partex CEF25016F-K 25 mm² insulated cord end ferrule helps overcome these issues by enclosing the stripped conductor strands within a conductive copper crimp sleeve.
The ferrule is fitted over the stripped conductor and compressed using a compatible crimping tool, producing a compact termination for insertion into a suitable electrical terminal. Its 16 mm metal barrel provides a defined termination length, while the black Polyamide 66 collar guides the conductor during installation and creates a neat transition between the cable insulation and conductive sleeve.
The tin-plated copper construction supports efficient electrical conductivity and helps protect the contact surface against corrosion. When correctly selected and crimped, the CEF25016F-K supports consistent termination quality and reliable electrical connections in industrial control panels, electrical distribution cabinets and other professional wiring assemblies.
Typical Applications
- Industrial electrical control panels and automation cabinets.
- Power distribution boards and electrical switchgear assemblies.
- Motor control centres and industrial machinery wiring.
- Electrical distribution cabinets and terminal blocks.
- Industrial automation and equipment control systems.
- Electrical cabinet manufacture and panel assembly.
- Building services electrical installations.
- OEM electrical equipment manufacture and production wiring.
- Electrical maintenance, servicing and refurbishment projects.
- High-volume preparation of 25 mm² flexible stranded copper conductors.

Frequently Asked Questions
What is the Partex CEF25016F-K cord end ferrule used for?
The Partex CEF25016F-K is used to terminate flexible stranded copper conductors before insertion into compatible electrical terminal blocks. It helps keep conductor strands together and provides a neat crimp termination for industrial control panels, power distribution equipment and machinery wiring.
What cable size is suitable for the Partex CEF25016F-K?
The CEF25016F-K is designed for a nominal conductor cross-section of 25 mm². It should be installed on compatible flexible stranded copper conductors using an appropriately sized ferrule crimping tool.
What is the barrel length of the Partex CEF25016F-K?
The ferrule features a 16 mm metal barrel length and an overall length of 28 mm. The barrel dimensions should be checked against the receiving terminal's conductor insertion requirements.
Why is the Partex CEF25016F-K ferrule black?
The black insulated collar follows the French-type colour coding system for 25 mm² cord end ferrules. This helps installers identify the correct conductor size during cable preparation and electrical assembly.
