Keep multiple sizes of our tightest-gripping butt splices on hand. After crimping your splice, apply a heat gun to shrink the plastic and grip wire 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 strongest-gripping reducing butt splices hold wire securely through heavy vibration and sharp tugs. Also known as step-down splices, reducing splices join a larger wire and a smaller wire end to end. Colored stripes differentiate the larger and smaller openings so you don't have to measure and mark them yourself.

An upgrade in strength and strain relief over standard reducing splices. After crimping your splice, apply a heat gun or butane torch to shrink the plastic and grip wire 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. Also known as step-down splices, reducing splices join a larger wire and a smaller wire end to end. Colored stripes differentiate the larger and smaller openings so you don't have to measure and mark them yourself.

One splice does the job of two—connect a single wire with two others of the same size to streamline your run. After crimping the splice, apply a heat gun to shrink the plastic and grip wire 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.

A step up in grip strength and strain relief over standard multi-direction splices. After crimping your splice, apply a heat gun to shrink the plastic and grip wire 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.

These splices streamline wiring for industrial control panels, automotive electrical systems, and other complex setups. The wires come together at the center of the splice like spokes on a wheel, contacting the hub without touching each other.

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.
