Wire joiners, also called butt connectors, join two wires end to end. Use them for extending a run or repairing a cut wire. Packs of 50.
Terminals are colour coded by wire size: red for 3mm wire, blue for 4mm and yellow for 5mm, so you can pick the right one without measuring.
| Product | Wire size |
|---|---|
| Red, 3mm wire | 3mm |
| Blue, 4mm wire | 4mm |
For joins that need sealing against water, use heat shrink wire joiners instead.
Crimp them with a ratchet crimping tool: it will not release until the crimp is complete, so every join comes out the same. Browse all types in our crimp terminals range.
