Insulated Male Bullet Connectors – 4mm/5mm Crimp (Red/Blue/Yellow)

Insulated male bullet connectors — push-fit crimp terminals with a coloured, insulated barrel and a solid metal bullet. Crimp onto the wire, then push the bullet into a matching female bullet socket for a neat in-line connection you can pull apart by hand. The listed size is the diameter of the metal bullet, and the anti-vibration copper insert grips the wire for a secure, reliable crimp.

Anti-vibration copper inserts

An extra copper ring inside the barrel bites into the wire and resists loosening under vibration, for a solid, repeatable crimp.
