Antique copper crimp tubes for 16-gauge jewelry wire. 10mm long Artistic Wire® Large Wire Crimp Connectors are the perfect cold connection to join large gauges of Artistic Wire together. Perfectly calibrated for 16-gauge Artistic Wires and other soft wires, you can also use them for Artistic Wire Braid, and to join multiple strands of smaller gauge wires. To use, place one end of the wire that you are joining half way into the Crimp Connector. Place the other wire in the opposite end so that the wires meet in the middle. For 16 gauge wires, use the back notch of Standard Crimping Pliers to gently squeeze one side of the crimp, then the other for a secure connection.
