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 conductivity from standard wire connectors. Twist your wires together and crimp them so they hold securely when tugged or jostled. For rain and splashes, choose heat-shrink crimp-on wire connectors instead. For wires on or around vibrating equipment, consider tight-hold heat-shrink connectors.

An economical alternative to our quick-connect clamp-on option, these splices are as quick to install but harder to adjust. Push wire into each end without the need for an installation tool. The splices have a test socket to safely test the voltage after installation.

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.

These connectors are as quick to install as our clamp-on option, though they're not as easy to adjust. They extend or terminate electrical connections in branch circuits, such as light fixtures and electronic devices. Push wire into place without the need for an installation tool. To break the connection later, you'll have to pull wire back out. The connectors also have test sockets to safely test voltage after installation.

DIN Rail Mounting Adapters—Clip connectors onto DIN 3 rail to keep them organized and easily accessible.

Covers—Seal out moisture to protect your connection. Covers are lined with a sticky gel, so you don't need to mix or pour a potting compound yourself. They’re rated IP08 to withstand splashes, rain, and humidity. To repair or expand your circuit, open the cover and remove the wires so you can reuse them. However, you'll need to replace the splice and cover after you open the cover and remove the gel.

These tap/connectors join larger wire sizes, such as power and control cable in distribution panels. Insert your main wire into a port, then insert tap wires into the other ports and tighten the set screws. The wires lock in place for a consistent and durable connection.

Twist onto the wire instead of crimping for fast and easy installation.

Add a new branch to your circuit the quick way—no need for a new power source or a wire stripper. These taps bite through insulation to draw power from an installed main wire to new tap wires. Slide in the unstripped main and tap lines, then close the tap and squeeze it with a crimper for a secure connection.

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.

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.

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.

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.

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.

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.

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.

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.
