    Terminal and Splice Kits

    Maintain a supply of extra terminals and splices in various sizes. Use a crimping tool (included with some kits) to install wire.
    Barrel Insulated, Fully Insulated
    Image of Product. Front orientation. Terminal and Splice Kits.
    Barrel-insulated terminals have a plastic cover to prevent short-circuiting with nearby wire.
    Fully insulated terminals have a connection tab that’s completely covered, leaving no metal exposed when mated.
    Nylon Insulation—Nylon insulation is more durable and chemical resistant than vinyl insulation.

    Twist-On Insulation-Piercing Wire Tap Assortments

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. Twist-On Insulation-Piercing Wire Tap Assortments.
    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.

    Watertight Insulation-Piercing Butt Splices

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. 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.

    Watertight Reducing Insulation-Piercing Butt Splices

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. 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.

    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.

    Cut and restore your tapped connection without rewiring. Instead of connecting to a bare tap line, these taps lock onto wires with quick-disconnect terminals on the end. First, insert your main line into the tap (no need to strip the wire first). Next, squeeze the tap with a crimper so it bites through the insulation for a secure connection. Crimp a quick-disconnect terminal (sold separately) onto your tap wire, then pop it in and out of the tap as often as you need.

    Covers

    Lay the main wire into your tap on the first try instead of poking and threading. The tap wire connects parallel to the tap or at 90°, so the tap will slide into your setup at different angles. Strip both wires and slide off the screw plate before installation. Tighten the set screws onto both wires for a secure connection.
    Covers—These covers fully insulate the tap so moisture can't reach the wire. They snap shut so you don't have to tape them down.
