Why Choose the Partex YFB50/VR Yellow Insulated Female Bullet Terminals?
The Partex YFB50/VR is a yellow insulated female bullet crimp terminal designed to provide secure, reliable and detachable electrical connections in industrial wiring, electrical equipment and control panel applications. Featuring a 5 mm nominal female bullet connector, this terminal is designed to mate with a compatible male bullet terminal, creating a convenient electrical connection without requiring screw or stud fastening.
As part of the Partex insulated male and female bullet terminal range, the YFB50/VR combines a conductive metal terminal with protective yellow insulation. The yellow colour identifies the commonly used 4–6 mm² conductor size range, making it suitable for larger stranded copper conductors in electrical wiring applications. Its VR vibration-resistant design is intended to help maintain dependable electrical contact in equipment exposed to movement and vibration.
Supplied in a convenient pack of 100 terminals, the Partex YFB50/VR is a practical solution for electricians, electrical maintenance engineers, panel builders and OEM equipment manufacturers. Its detachable bullet connection is particularly useful for machinery wiring, equipment servicing and electrical assemblies where conductors may need to be disconnected and reconnected during maintenance.

Reliable Bullet Connections for Industrial Electrical Wiring
Bullet terminals provide a convenient method of connecting electrical conductors using mating cylindrical male and female contacts. The Partex YFB50/VR female bullet terminal is designed to accept a compatible 5 mm male bullet connector, creating a detachable electrical connection that can be separated when equipment requires inspection, servicing or replacement.
The terminal's VR vibration-resistant construction makes it particularly suitable for wiring assemblies where mechanical movement or vibration may be present. Its yellow insulation helps identify the nominal conductor size range while providing protection around the crimp termination. When correctly installed, the crimp connection helps maintain reliable conductor retention and electrical continuity.
For correct installation, the conductor should be stripped to the appropriate length and inserted fully into the terminal barrel before crimping with a suitable tool and die for yellow insulated 4–6 mm² terminals. The completed connection should be checked for secure conductor retention and correct engagement with the mating male bullet terminal. Both connectors must be compatible in size and design, and any additional insulation or electrical protection required by the installation must be provided.
Typical Applications
- Industrial machinery wiring and electrical equipment assembly.
