Why Choose the Partex RR37/RA Red Insulated Ring Terminal?
The Partex RR37/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 M3.5 stud connection, this crimp terminal provides a practical method of connecting stranded conductors to compatible screw terminals, terminal studs and electrical connection points.
As part of the Partex electrical crimp terminal range, the RR37/RA combines a ring-shaped contact with an insulated conductor entry to support dependable electrical connections. The closed-ring design helps retain the terminal beneath the fastening screw or nut, reducing the likelihood of accidental disconnection compared with open-ended terminal designs when correctly installed.
Featuring red insulation and supplied in a convenient pack of 100 terminals, the Partex RR37/RA is suitable for electrical contractors, panel builders, maintenance engineers and OEM manufacturers requiring consistent conductor terminations for professional electrical wiring applications.

Reliable Electrical Connections for Industrial Wiring
Insulated ring terminals provide a practical solution for connecting electrical conductors to screw and stud terminals. The Partex RR37/RA features a closed-ring contact that surrounds the fastening point, helping maintain mechanical retention once the connection is correctly tightened. This makes ring terminals particularly useful in electrical equipment where a secure conductor connection is important.
The red insulated sleeve helps identify the termination and provides insulation around the conductor entry. For reliable performance, the terminal must be matched to the appropriate conductor cross-section, crimping tool and M3.5 fastening point. Correct conductor preparation, crimping and tightening are essential for achieving a secure electrical connection.
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.
