Why Choose the Partex RR105/RA Red Ring Terminal?
The Partex RR105/RA is a red insulated ring crimp terminal designed for connecting electrical conductors to compatible M10 threaded studs, screws and terminal posts. Supplied in a convenient pack of 100, these terminals provide a practical solution for professional electrical installations, control panel wiring, equipment assembly and maintenance.
The closed-ring connection design allows the terminal to be secured beneath a suitable nut or screw head, helping maintain mechanical retention at the electrical connection point. Its red insulated crimp barrel provides convenient visual identification and helps cover the conductor termination area.
The RR105/RA is intended for applications requiring an M10 ring connection and a suitably matched conductor. The terminal is installed using an appropriate crimping tool, providing a solder-free method of attaching a ring connector to a prepared electrical cable. Its pack quantity makes it useful for electricians, panel builders, electrical equipment manufacturers and maintenance engineers carrying out repeat termination work.

Secure M10 Ring Connections for Electrical Installations
Ring terminals are widely used in electrical wiring because they provide a convenient method of securing a conductor to a threaded electrical connection point. Unlike open-ended fork terminals, a closed-ring terminal remains captured around the fixing stud until the nut or screw is removed. This makes ring connectors particularly useful where secure attachment and straightforward maintenance are important.
The Partex RR105/RA combines an M10 ring fixing with a red insulated crimp barrel. The insulation helps cover the termination area, while the crimp connection provides a mechanical and electrical interface between the conductor and terminal when correctly installed. The terminal can be used in suitable control panels, electrical equipment and industrial wiring assemblies.
For installation, the conductor should be stripped to the correct length without damaging its strands. The prepared conductor is inserted into the terminal barrel and crimped using a tool and die suitable for the terminal and conductor combination. The completed ring termination is then positioned over a compatible M10 stud and secured using the equipment manufacturer's specified fastening method and tightening torque.
Before use, installers should confirm the conductor cross-sectional area, terminal dimensions, electrical ratings and suitability for the installation environment. Red insulation is a useful identification feature, but the correct wire size and crimping requirements should always be established from the relevant product specifications rather than colour alone.
Typical Applications
- Electrical control panel and distribution equipment wiring.
- Connections to compatible M10 studs and terminal posts.
- Industrial machinery and electrical equipment assembly.
- Electrical cable harness manufacturing and repair.
- Maintenance and replacement of insulated ring terminal connections.
- Professional electrical installations requiring secure screw-fixed conductor terminations.
