Why Choose the Partex RR43/RA Red Insulated Ring Terminal?
The Partex RR43/RA is a reliable red insulated ring terminal designed for secure electrical conductor termination in industrial control panels, electrical installations and equipment wiring. Featuring an M4 stud connection, this crimp terminal provides a practical method of connecting stranded electrical conductors to compatible screw terminals, terminal studs and electrical connection points.
As part of the Partex electrical crimp terminal range, the RR43/RA combines a closed-ring contact with an insulated conductor entry to support dependable electrical connections. The ring-shaped design surrounds the fastening screw or stud, helping maintain terminal retention once the connection is correctly tightened. This makes it suitable for applications requiring secure and serviceable electrical terminations.
Featuring red insulation and supplied in a convenient pack of 100 terminals, the Partex RR43/RA is ideal for electrical contractors, panel builders, maintenance engineers and OEM manufacturers requiring consistent conductor terminations for professional electrical wiring and assembly applications.

Reliable Electrical Connections for Industrial Wiring
Insulated ring terminals provide a practical and secure method of connecting electrical conductors to screw and stud terminals. The Partex RR43/RA features a closed-ring contact that surrounds the fastening point, helping maintain mechanical retention once the connection is correctly tightened. Unlike open-ended terminal designs, a ring terminal generally requires the fastening screw or nut to be removed before the conductor can be disconnected.
The red insulated sleeve helps identify the termination and provides insulation around the conductor entry. For reliable performance, the terminal should be matched to the correct conductor cross-section, suitable crimping tool and compatible M4 fastening point. Proper conductor preparation, crimping and tightening help achieve consistent electrical continuity and mechanical security in industrial wiring installations.
Typical Applications
- Industrial electrical control panels and switchgear wiring.
- Electrical distribution equipment and terminal connections.
- Machinery control circuits and automation systems.
- Electrical equipment manufacturing and assembly.
- Maintenance, repair and replacement of electrical terminations.
- OEM panel building and general industrial wiring installations.
