Non-Insulated Butt Connector 22-18GA

A3B

$0.04

| /

Butt connector for joining two 22–18 AWG stranded copper wires end to end. It is tin-plated copper with no insulation: insulate it with heat shrink after crimping, or use it inside a protected enclosure.

Use it for: repairing or extending sensor, signal and LED wiring where you will seal the joint with heat shrink, or inside a protected enclosure.

Getting the right size: match the barrel to the wire gauge. Same non-insulated butt connector for other gauges: 16–14 AWG · 12–10 AWG · 8 AWG · 6 AWG · 4 AWG · 2 AWG · 1/0 AWG · 2/0 AWG · 3/0 AWG · 4/0 AWG. Same size, different construction: high temp (900°F), vinyl, nylon, heat shrink (waterproof).

Priced per piece — order any quantity. Seal it with adhesive-lined dual wall heat shrink. See all butt connectors.
