For use where water and contaminants are a concern, the terminals and splices in these assortments have insulation that shrinks and creates a tight seal when heated. Use a crimping tool (included with some assortments) to install wire.

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/polyolefin insulation is more durable than polyolefin insulation.

Keep splicing connectors on hand for two, three, or five wires. Press down on the clamp to connect wires and pull it up to disconnect. The splicing connectors are clear, so you can see the connection. They have two test slots to check voltage after installation.

Designed for use in high-temperature applications such as motors, ovens, and furnaces, these assortments include a variety of terminals and splices made of heat-resistant materials. They are noninsulated, so you can easily inspect the wire connection. Use a crimper (not included) to install wire.

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.

Secure wire faster than twisting and crimping with the connectors in these kits. Push stripped wire into them for a reliable connection. They have a clear housing, so you can see the connection. Use an adapter to mount connectors to a DIN rail.

A good choice for jobs where you don’t have crimping tools on hand, these connectors twist on to install wire quickly. Some connectors are easy grip, so they have wings that increase your leverage when tightening.

When the splices in these assortments are heated, the enclosed solder melts to create the most secure, electrically conductive, and environmentally sealed connection we offer. They have an adhesive-lined insulation that shrinks and bonds to wire when heated, protecting it from water and corrosion.

Convenient for jobs when you don't have a crimping tool on hand, these butt splices have end caps that you twist instead of traditional crimping. The end caps lock the wire in place, making them good for high-vibration applications.

Keep a variety of ferrule sizes on hand. These ferrules add strength and stability to stranded wire, protecting it from damage. They also make it faster to insert the wire into terminal blocks. Use a crimper (not included) to install wire.

Barrel-insulated ferrules have a plastic cover to prevent short-circuiting with nearby wire. Nylon-insulated ferrules are more durable and resist chemicals better than polypropylene.

Noninsulated ferrules allow you to easily inspect the wire connection.

Use ferrules for two wires to insert two wires into one terminal block.

Keep a variety of quick-disconnect terminal sizes on hand. These terminals slide together and pull apart with ease, so they are convenient in applications that require frequent connections. Use a crimper (not included) to install wire.

Barrel-insulated terminals have a plastic cover on the barrel to prevent short-circuiting with nearby wire.

Fully insulated terminals have a completely covered connection tab—no metal is exposed when they are mated. Made of nylon, they are more durable and resist chemicals better than vinyl insulation.

Noninsulated terminals are best when you don’t need insulation and want to easily inspect the wire connection.

Keep a variety of ring terminal sizes on hand.

For technical drawings and 3-D models, click on a part number.

Keep a variety of lug sizes on hand. Either solder these lugs into place, or use a hammer-on crimper (not included) for a secure connection.

Keep on hand the set screw lugs, nuts, and bolts needed to install single- or three-phase dry-type transformers. Tighten the set screw onto your wire for a secure connection without crimping.

No crimping or wire stripping needed—this assortment includes twist-on wire connectors and insulation-piercing wire taps.
