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.

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.

End caps seal off the wire to keep your connection completely dry and conductive. Set screws cinch the wire without denting the body, so you can pop splices on and off for adjustments and reuse. For cable, attach each wire to its own set screw.

The choice for outdoor electrical panels, HVAC systems, and anywhere you're concerned about moisture. A gel filler repels moisture to keep your wires dry and conductive.

These connectors bite through insulation, so you save time and avoid damage from a wire stripper. For the most dependable connection, use a crimping tool to squeeze connectors onto your wire.

Unlike other wire taps, a gel filler repels moisture to keep your connection dry and conductive. These taps bite through insulation to draw power from an installed main wire to a new tap wire. No need to cut or strip your wire—slide in the main and tap lines, then close the tap and squeeze it with a crimper for a secure connection.

Insert wires end to end and lock them in place with the twist of a cap. These splices resist vibration and pulling to keep a secure connection between wires. They're convenient for field installations when you don't have crimping tools handy.

With a tighter grip than other insulation-piercing wire options, these taps secure wire around motors and other high-vibration equipment. Twist the cap to lock the tap onto the main wire. The tap will bite through the insulation to establish a connection. Next, strip your tap wire and thread it into the tap to draw power and create a new circuit.

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.
