Noninsulated butt connectors made from copper tubular material with electro tin plating for durable, longlasting performance in a variety of settings. Secure connections with a wire stop barrier that ensures compression, delivering reliable and safe electrical connections. Wide range of applications including machinery wiring, electrical power systems, household appliances, aviation applications, shipbuilding projects, and railway equipment work. Substantial quantity: 380 pieces per box, covering wires from 22 to 6 AWG. Use scenarios In factory maintenance, connect 226 AWG conductors in control panels or motor wiring assemblies. The wire stop barrier helps achieve correct compression for secure, durable joints during routine servicing. At home or in a workshop, or extend power leads for household appliances, using 226 AWG cables where a quick, reliable crimp is required. In aviation, shipbuilding, or railway projects, perform robust electrical connections in harsh or demanding environments, taking advantage of the coppertubular construction and electro tin plating for corrosion resistance and lasting performance.
