Heat Shrink 3-Way Connector 22-18GA

Heat Shrink 3-Way Connector 22-18GA

| /

Waterproof 3-way splice that joins three 22-18 AWG stranded copper wires in one connector — one wire in, two out, or two in, one out. The adhesive-lined heat shrink sleeve melts and seals around the wire insulation when heated, blocking moisture, salt and road spray from reaching the crimp. Made in USA.

Use it for: tapping a feed to power a second light or accessory, or joining two grounds to one lead, on boats, trailers, truck and off-road wiring, outdoor lighting and anywhere a connection sees water, washdown or vibration.

Choose something else if: you only need to join two wires — a heat shrink butt connector is simpler. For dry locations the nylon or vinyl 3-way connectors crimp without a heat gun.
