YR43/RA Partex Ring Terminals, M4, Yellow, pack 100

Why Choose the Partex YR43/RA M4 Yellow Ring Terminal?

The Partex YR43/RA is a professional yellow insulated ring terminal designed for terminating electrical conductors at compatible M4 screw and stud connections. Featuring a closed-ring connection, yellow insulation and a convenient pack of 100 terminals, this electrical accessory provides a practical solution for control panel wiring, industrial machinery and electrical equipment assembly.

As part of the Partex range of electrical cable termination accessories, the YR43/RA supports secure and organised conductor connections. Its closed-ring design allows the terminal to be retained around the fastening screw or stud once correctly installed, making it suitable for applications where a captive connection is preferred over an open-ended fork terminal.

The Partex YR43/RA M4 ring terminal combines a crimp-style conductor termination with a yellow insulated sleeve to support consistent wire preparation and identification. Supplied in a pack of 100, it is a practical choice for electricians, panel builders, OEM equipment manufacturers and industrial maintenance technicians requiring reliable electrical termination accessories.

Secure M4 Ring Terminal Connections for Industrial Electrical Wiring

Ring terminals are commonly used to connect electrical conductors to screw and stud terminals in industrial electrical installations. Unlike open-ended spade terminals, a ring terminal features a closed connection opening that surrounds the fastening hardware. This configuration helps retain the terminal in position when the screw or nut is correctly fitted and tightened.

The Partex YR43/RA features an M4 ring connection and yellow insulated sleeve, making it suitable for electrical assemblies that require these characteristics. The insulated entry supports organised conductor termination, while the ring connection provides a practical interface for compatible terminal hardware.

For dependable installation, the conductor cross-section must be matched to the terminal's specified wire capacity, and the crimp must be completed using a compatible tool and die. Yellow is commonly associated with larger insulated crimp terminal sizes, but the exact conductor range for the YR43/RA should be verified against the applicable Partex specification rather than assumed from colour alone. The completed connection must also be installed using the tightening requirements specified by the receiving equipment manufacturer.

Typical Applications

• Industrial electrical control panel wiring.
• Electrical distribution and control assemblies.
• Motor control and industrial machinery wiring.
• Electrical equipment screw and stud connections.
• Automation and OEM equipment manufacturing.
• Compatible electrical terminal and connection points.
• Electrical installation, servicing and maintenance.
• Replacement and refurbishment of electrical conductor terminations.
