Why Choose the Partex PXL25-6 Copper Tube Ring Terminal?
The Partex PXL25-6 copper tube ring terminal is a professional medium-duty, uninsulated electrical crimp lug designed for terminating 25 mm² copper conductors onto M6 studs and bolts. Manufactured from high-conductivity copper with a protective bright electro-tinned finish, this terminal provides a dependable electrical connection for power distribution assemblies, industrial control panels, electrical equipment and heavy-duty cable installations.
Part of the Partex PXL copper tube terminal range, the PXL25-6 features a bell-mouth barrel entry that helps guide the conductor into position during installation. An integrated inspection hole allows electricians to check that the cable is fully inserted before crimping, helping improve installation accuracy and connection consistency. Its closed-ring palm provides a secure connection to compatible M6 terminal studs, busbars and electrical equipment connection points.
Supplied in a convenient pack of 50 terminals, the Partex PXL25-6 is an excellent choice for electrical contractors, industrial panel builders and maintenance engineers carrying out repeated cable terminations. With a 6.8 mm barrel internal diameter, 13.0 mm palm width and 33.0 mm overall length, this compact copper lug combines practical installation features with reliable mechanical and electrical performance.

Secure 25 mm² Crimp Connections for Industrial Power Distribution
The Partex PXL25-6 M6 copper tube terminal provides a practical method of connecting 25 mm² copper cables to stud-mounted electrical equipment. Its tubular barrel is designed to accommodate a correctly prepared conductor, while the bell-mouth entry assists insertion. Before crimping, the inspection hole enables installers to verify that the conductor has been inserted correctly. When compressed using an appropriate crimping tool and die, the barrel forms a secure mechanical and electrical connection with the cable.
For reliable installation, electricians should confirm the conductor size, construction and stud compatibility before selecting the terminal. The cable insulation should be stripped to the appropriate length without damaging the copper strands, and the lug should be crimped using the recommended tool and die combination. After crimping, the termination should be inspected and secured to the M6 connection point using the equipment manufacturer's specified tightening method. As the PXL25-6 is uninsulated, suitable insulation, sleeving or protective barriers may be required depending on the installation.
Typical Applications
- Industrial electrical control panel manufacturing.
- Termination of 25 mm² copper conductors onto M6 studs.
- Electrical distribution boards and switchgear assemblies.
- Industrial power distribution and electrical equipment connections.
- Motor control centres and industrial automation systems.
- Machinery wiring and manufacturing plant electrical installations.
- Busbar connections and stud-mounted terminal assemblies.
- Commercial electrical infrastructure and maintenance work.
- OEM electrical equipment production and cable assembly.
- Repair and replacement of existing copper ring terminal connections.
