Why Choose the Partex COL25-5/RA Right-Angle Copper Tube Terminal?
The Partex COL25-5/RA is a professional 25 mm² right-angle copper tube ring terminal designed for terminating electrical conductors onto equipment fitted with an M5 stud or bolt connection. Featuring a copper tube conductor barrel and an angled ring fixing, this terminal provides a practical solution for electrical installations where cable routing, equipment layout or restricted connection space requires a right-angle termination.
Designed for use with appropriately sized 25 mm² conductors, the Partex COL25-5/RA combines a crimp-style conductor connection with an M5 ring fixing. Its right-angle configuration allows the cable to approach the connection point from a different direction than a conventional straight ring terminal, making it useful for compatible electrical panels, machinery connections and equipment assemblies where cable orientation is an important consideration.
Manufactured from copper, the COL25-5/RA provides a conductive termination component for professional electrical applications. The closed ring fixing is designed to be secured beneath suitable stud or bolt hardware, helping retain the terminal when correctly installed. The angled construction can assist with cable routing and connection positioning, provided the complete installation meets the equipment manufacturer's electrical and mechanical requirements.
Supplied in a convenient pack of 100 terminals, the Partex COL25-5/RA is particularly suitable for electrical contractors, control panel manufacturers, OEM machinery builders and industrial maintenance departments carrying out repeated cable termination operations. The bulk pack supports consistent component selection across electrical assembly, equipment manufacturing and maintenance projects.

Right-Angle Copper Tube Terminals for Electrical Panels and Machinery
Electrical cable terminations must be selected to suit both the conductor and the physical arrangement of the equipment connection. In some installations, a conventional straight ring terminal may require an inconvenient cable approach or additional space for conductor routing. The Partex COL25-5/RA right-angle copper tube terminal provides an alternative configuration for applications where an angled connection is appropriate.
The terminal combines a 25 mm² copper tube conductor connection with an M5 ring fixing. Its right-angle arrangement allows the conductor to approach the fastening point from a different direction than a straight terminal. This can be useful in electrical enclosures, machinery assemblies and connection areas where the relative positions of the cable entry, terminal stud and surrounding components influence the termination layout.
Correct cable routing remains essential when installing an angled terminal. The conductor must not be forced into position or subjected to excessive bending, pulling or twisting at the crimped connection. Adequate space should be provided for the cable's permitted bending radius, terminal hardware, electrical clearances and any required insulation or protective sleeving.
The 25 mm² conductor size and M5 stud connection must also be assessed together. An M5 fastening point should not automatically be assumed to support the electrical loading or mechanical requirements associated with a 25 mm² conductor. The equipment terminal rating, contact arrangement, fastening hardware and manufacturer's technical data must be checked to confirm that the complete connection is suitable.
Crimping and Installation Considerations
To achieve a suitable electrical connection, the conductor should be prepared according to the manufacturer's instructions and inserted correctly into the copper tube barrel. Crimping must be carried out using tooling and dies compatible with the terminal and conductor construction. The completed crimp should be inspected for correct positioning, mechanical security and any visible damage.
When fitting the terminal to an M5 stud or bolt, the ring should be positioned so that it sits correctly against the intended contact surface without introducing unnecessary mechanical stress. The fastening hardware should be installed and tightened according to the equipment manufacturer's specifications. Any required electrical insulation, protective sleeving or enclosure protection should be provided as part of the completed installation.
The right-angle configuration should be selected only where it matches the physical layout of the equipment and allows the conductor to follow an appropriate route. Where cable movement, vibration or mechanical loading may occur, suitable cable support and strain relief should be considered.
