    Wire Tap/Connectors

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. Wire Tap/Connectors, Single-Sided Entry.

    Single-Sided

    Entry

    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.
    Single-Sided Entry—Insert all your wires from the same side. The slim profile fits better in crowded panels and boxes than dual-sided entry tap/connectors.

    Crimp-On Butt Splices

    Extend a run or repair damaged wire instead of installing a new line. Squeeze the wire splice with a crimping tool for a secure end-to-end connection.
    Vinyl Plastic Insulation—Our basic insulation covers the wire to prevent short circuits. It won’t break down from dirt, grime, and occasional twists and tugs.
    Nylon Insulation—In addition to preventing short circuits, this wear-resistant insulation protects wire from vibration and rubbing against nearby edges.
    Double Crimp—The choice for wire that’s frequently pulled, bent, or vibrated. Crimp the splice twice on each end for an extra-strong grip on the wire.

    A step up in grip strength and strain relief over standard butt splices. After crimping your splice, apply a heat gun to shrink the plastic and grip wire 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.
    Nylon Insulation—In addition to preventing short circuits, this wear-resistant insulation protects wire from vibration and rubbing against nearby edges.
    Polyolefin Insulation—A durable, economical choice when you don't need the extra wear resistance of nylon.
    With Window—Troubleshoot bad connections without removing your splice. The splice has a cutout where the wires meet, so you can confirm at a glance that they're crimped evenly and haven't loosened.

    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.

    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.

    One splice does the job of two—connect a single wire with two others of the same size to streamline your run. After crimping the splice, apply a heat gun to shrink the plastic and grip wire 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.

    Reducing Crimp-On Butt Splices

    Connect two components with different wire sizes, such as a large 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. Colored stripes differentiate the larger and smaller openings so you don't have to measure and mark them yourself. Attach your wire with a crimping tool to avoid a damaged splice and loose connection.

    Moisture-Resistant Twist-On Butt Splices

    Unlike other twist-on butt splices, sealed end caps block out moisture and keep your wire dry and conductive. Insert wires end to end and lock them in place with the twist of a cap. These splices resist vibration and pulling to keep a secure connection between wires. Use them to speed up field installations without the use of crimping tools.

    Tight-Hold Heat-Shrink Reducing Butt Splices

    Image of Product. Front orientation. Wire Splices, Connectors, and Taps. Tight-Hold Heat-Shrink Reducing Butt Splices.
    Our strongest-gripping reducing butt splices hold wire securely through heavy vibration and sharp tugs. Also known as step-down splices, reducing splices join a larger wire and a smaller wire end to end. Colored stripes differentiate the larger and smaller openings so you don't have to measure and mark them yourself.
    Solder and Crimp-On Connection—The tightest hold you can get. First, squeeze the splice firmly and evenly onto the wire with a crimping tool. Next, melt the heat-shrink insulation and enclosed solder to add even more stiffness and strength.
    Polyolefin Insulation—The durable plastic maintains a tight grip on the wire so it stays put when pulled or vibrated.

    A step up in grip strength and strain relief over standard multi-direction splices. After crimping your splice, apply a heat gun to shrink the plastic and grip wire 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.
    These splices streamline wiring for industrial control panels, automotive electrical systems, and other complex setups. The wires come together at the center of the splice like spokes on a wheel, contacting the hub without touching each other.

    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.

    Connect large wires of different sizes, as thick as 4/0 AWG. Colored stripes differentiate the larger and smaller openings so you don't have to measure and mark them yourself. Check the color coding, wire gauge, and compression die reference number on the splice to match it with the right compression tool.
    With Window—Troubleshoot bad connections without removing your splice. The splice has a cutout where the wires meet, so you can confirm at a glance that they're crimped evenly and haven't loosened.

    Break and restore your tapped connection without rewiring. Instead of connecting to a bare tap line, these taps lock onto wires with snap-plug 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 snap plug (sold separately) onto your tap wire, then pop it in and out of the tap as often as you need.

    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.
