BS43 Partex Blue 4mm Fork Crimp (PK100)

Why Choose the Partex BS43 Blue Insulated Fork Terminal?

The Partex BS43 is a premium PVC insulated fork (spade) crimp terminal designed to provide secure, durable electrical terminations for stranded copper conductors. Manufactured from high-conductivity C1100 tin-plated copper with robust blue PVC insulation, it delivers reliable electrical performance, corrosion resistance and long service life in industrial, commercial and OEM electrical installations.

Part of the trusted Partex BS insulated fork terminal range, the BS43 is engineered to minimise conductor strand damage while producing secure, vibration-resistant electrical connections. The open fork design allows conductors to be disconnected without completely removing the fixing screw, simplifying maintenance and reducing downtime.
