Submersible Insulation-Piercing Butt Splices

For 2 Wires

For 4 Wires

Pierce the insulation of wire without stripping it to make quick connections that are also sealed to keep out water. These splices have termination buttons on each end, so you can make independent connections on both sides. Since you connect each end independently, they’re often used as a disconnect point on equipment that you’ll be moving around. To install these splices, use a pair of pliers to press down on the button until it clicks.

On 2-wire splices, each button comes in one of three colors that correspond with wire gauge, making it easy to match your wire to the right connector.

4-wire splices have two entry points on both ends for twice as many independent connections as 2-wire splices.

Harsh-Environment Screw-Down Butt Splices

Splice for Four Wires

Splice for Eight Wires

Join wires and cables in some of the dirtiest and wettest locations—from paper mills to marine environments—without special tools. With a nylon body and gasketed end caps, these splices are IP68 rated to seal out dust and water even if briefly submersed. To install, insert wire into either side, tighten the screws with a slotted screwdriver, and twist on the end caps to seal. They have multiple terminals, so you can repair, extend, and reconfigure cables with multiple wires.

Underground Heat-Shrink Screw-Down Butt Splices

For 1 Wire

For 3 Wires/UF Cable

Make watertight connections for underground applications. These splices are abrasion-resistant and can withstand burial in rocky soil. They come with a length of heavy-wall polyolefin heat-shrink tubing that fits over the splice. Tighten the screws to connect wires.

Underground Twist-On Wire Splicing Connectors

Make quick, watertight connections for underground applications without any crimping. These connectors are filled with silicone, so they seal out moisture and prevent corrosion. Because you twist to connect wire by hand, they're ideal for jobs where you don’t want to carry around a lot of tools.
