Why Choose the Partex COL1.5-4 Copper Tube Ring Terminal?
The Partex COL1.5-4 is a copper tube ring terminal designed for terminating 1.5 mm² electrical conductors onto an M4 threaded stud or terminal connection. Supplied in a convenient pack of 100 terminals, it provides a practical solution for creating secure, mechanically fastened electrical connections in control panels, distribution equipment and industrial electrical installations.
The copper construction provides an electrically conductive connection between the cable and the termination point. Its tubular barrel is designed to accommodate the conductor for crimp termination, while the ring-shaped mounting eye allows the terminal to be secured using a compatible stud, screw or bolted connection.
With its 1.5 mm² conductor size and M4 stud compatibility, the Partex COL1.5-4 is suitable for electrical installers, panel builders and maintenance engineers requiring consistent cable terminations in industrial and commercial electrical systems.

Reliable Crimp Connections for Electrical Installations
Copper tube ring terminals provide a practical method of connecting electrical conductors to equipment terminals, busbar connection points and threaded studs. The Partex COL1.5-4 combines a tubular crimp barrel with a closed-ring mounting eye, allowing a correctly prepared 1.5 mm² conductor to be terminated and mechanically fastened to a compatible M4 connection.
For dependable installation, the conductor should be prepared and crimped using tooling suitable for the terminal design and conductor size. The completed ring terminal should then be fastened according to the equipment manufacturer's instructions. Correct crimping, cable selection and fastening are essential for maintaining electrical continuity and reducing the risk of loose or overheated connections.
Typical Applications
- Industrial electrical control panel wiring.
- Electrical distribution boards and switchgear assemblies.
- Terminal connections on electrical equipment.
- Machinery control and automation installations.
- Electrical maintenance and cable replacement work.
- Commercial and industrial wiring installations.
- Equipment manufacturing and electrical panel building.
