A step up in grip strength and strain relief over standard crimp-on wire connectors. First, twist your wires together and crimp them in the connector. Then, apply a heat gun to shrink the insulation and hold wires securely under tension and vibration. The heat shrink also protects wire from the drips, dirt, and scuffs that lead to fraying, poor conductivity, and short circuits.

Our tightest-holding connectors secure wire through heavy vibration and sharp tugs. Apply a heat gun or butane torch to shrink the insulation and firmly grip the wire. As the connector heats up, the enclosed solder melts around the wire for a stronger, more rigid connection than unsoldered wire.
