Insulated Butt Connectors – Crimp Wire Splice (Red/Blue/Yellow)

Insulated butt connectors — straight crimp splice terminals for joining two wires end-to-end. Strip both wire ends, insert one into each side of the barrel and crimp to make a fast, permanent inline join. The PVC insulation is colour-coded to wire size and covers the whole connection, so there's no exposed metal once crimped.
