Watertight Insulation-Piercing Butt Splices

A gel filler seals out water to keep your wires completely dry and conductive. No need to strip your wire—insert insulated wires into the splice, then squeeze the button with a crimper or pliers until it clicks. The splice bites through the insulation, so you don't take extra time or risk nicks and cuts from a wire stripper. Snap splices together to create the exact setup you need.

Moisture-Resistant Twist-On Wire Connectors


Straight Grip	Low-Profile Easy-Grip Wing

Unlike other twist-on connectors, a silicone filler repels moisture to keep your wire dry and conductive. These connectors twist on and off your wire to save time over crimp-on connectors. You can bury them in soil to power everything from irrigation systems to landscape lights. The connectors have a lower maximum voltage when buried.

Low-Profile Easy-Grip Wing—Our slimmest twist-on connector is the best fit for crowded outlet boxes and other cluttered areas.

Watertight Set Screw Butt Splices

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.

Protect utility, irrigation, and other underground connections from groundwater, rocky soil, and mechanical stress. After tightening the set screws, slide the heavy-wall polyolefin tube onto the splice. Then, apply a heat gun to shrink the tube and completely seal out moisture and dirt.

Watertight Reducing Insulation-Piercing Butt Splices

Connect two components with different wire sizes, such as an 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. The larger and smaller openings are color coded so you don't have to measure and mark them yourself. You can snap splices together to create the exact setup you need.

A gel filler seals out water to keep your wires completely dry and conductive. No need to strip your wire—insert insulated wires into the splice, then squeeze the button with a crimper or pair of pliers until it clicks. The splice bites through the insulation, so you don't take extra time or risk nicks and cuts from a wire stripper.

Underground Twist-On Wire Connectors

A go-to for underground feeder lines, these connectors stand up to pressure and wear when buried in the polypropylene cover. Strip your wires and slide them side by side into the opening. To connect, twist the easy-grip wing for a tight grip on the wire without straining your arm.
