Tight-Hold Heat-Shrink Butt Splice Assortments

Keep multiple sizes of our tightest-gripping butt splices on hand. 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.

Polyolefin Insulation—The durable plastic maintains a tight grip on the wire so it stays put when pulled or vibrated.

Underground Heat-Shrink Set Screw Butt Splices


Style A	Style B

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.

Wire Tap/Connectors

Single-Sided

Entry

Dual-Sided

Entry

Inline 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.

Dual-Sided Entry—Stagger multiple wires running from opposite directions—especially rigid wire that won't bend around the connector. For a safe flow of current, attach only one wire per port. Wires connected on both sides may overload the port, causing the connector to overheat and fail.

Inline Entry—Connect wires from opposite directions to create a straight run. Similar to butt splices.

Aluminum and Copper (For Joining Dissimilar Metals)—Aluminum and copper don't play well together, but these connectors keep them in line. They cover the wires with an antioxidant compound so the aluminum wire—and the whole connection—won't oxidize and corrode.

Quick-Connect Clamp-On Wire Connector Assortments

Install and service setups for two, three, and five wires, then reuse these connectors later. They pop on and off wire with the flip of a clamp to save time over crimping. Choose them for setups that change often, such as prototypes and testing. They even have test sockets to safely test voltage after installation. The assortments include DIN-rail adapters so you can snap connectors into a control panel.

Quick-Connect Push-On Wire Connector Assortments

Install and service setups for two to eight wires. These assortments include DIN-rail adapters so you can snap connectors into a control panel. Quick-connect push-on connectors are as fast to install as our clamp-on option, though they're not as easy to adjust. 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.

Underground Wire Tap/Connectors


Single-Sided Entry	Offset Entry

Plugged and sealed at every opening, these tap/connectors protect wire from groundwater and rocky soil. The trim-to-size port plugs create a tight seal where the wire enters. The other plugs have double O-rings to seal off gaps around the set screws.

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.

Offset Entry—Attach wires running from opposite directions—especially rigid wire that won't bend around the connector. The connection points are staggered so that current flows freely instead of concentrating in one spot and causing a fault.

Tight-Hold Heat-Shrink-Insulation Terminal and Splice Kits

Keep on hand a variety of different sized terminals and splices with the most secure, sealed connection we offer. Heat the outside and the enclosed solder melts to secure your wire. The insulation also shrinks when heated, keeping out water and contaminants.

Ring, quick-disconnect, and spade terminals have insulation covering the barrel to prevent short circuiting with nearby wire. Butt splices have a fully insulated connection tab, so no metal is exposed when they’re mated.

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.
