Flip a clamp onto your wire instead of crimping to speed up installations and reuse your splice later. Choose these splices for setups that change often, such as prototypes and testing. They even have test sockets to safely test voltage after installation.

A step up in grip strength and strain relief over standard butt 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.

Extend a run or repair damaged wire instead of installing a new line. Squeeze the wire splice with a crimping tool for a secure end-to-end connection.

Connect large wires of different sizes, as thick as 4/0 AWG. Colored stripes differentiate the larger and smaller openings so you don't have to measure and mark them yourself. Check the color coding, wire gauge, and compression die reference number on the splice to match it with the right compression tool.

Plugged and sealed at every opening, these tap/connectors protect wire from groundwater and rocky soil. The trim-to-size port plugs create a tight seal where the wire enters. The other plugs have double O-rings to seal off gaps around the set screws.

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.

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.

Connect two components with different wire sizes, such as a large air compressor and its control panel. Also known as step-down splices, these 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. Attach your wire with a crimping tool to avoid a damaged splice and loose connection.
