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.

Keep different sizes of connectors on hand and twist them onto wires for quick installation.

These connectors hold wire more securely than crimp-on connectors, so they're a better choice for high-vibration setups. They're also quicker to install and reusable because you don't crush them with a crimping tool. Tighten the set screw into the metal barrel inside the connector for a secure grip on the wire.

Keep multiple sizes of wire taps on hand to tap any wiring in your facility. With a tighter grip than other insulation-piercing options, these taps secure connections around motors and other rattling or jolting 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.

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.

Keep multiple sizes on hand to connect wire without crimping or wire stripping.
