Electrical Connector Crimpers

Terminal and Splice Crimpers

They may look like normal pliers, but these tools have a built-in crimping die.

Terminal and Splice Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

High-Voltage Terminal and Splice Crimpers

The rubber grip provides protection up to 1,000 volts AC.

High-Force Terminal and Splice Ratchet Crimpers

With one ton of compression force and an ergonomic design, this crimper reduces fatigue when crimping.

Quick-Change Terminal and Splice Ratchet Crimpers

Dies snap in and out of this tool, so you can quickly change from crimping one electrical connector type to another.

Wire Ferrule Crimpers

These crimpers have individual square crimping slots for each wire gauge.

Confined-Space Wire Ferrule Crimpers

Because you insert the wire ferrule from the front, this tool is useful in tight spaces.

Pin-and-Sleeve Contact Crimpers

Crimp open- and closed-barrel pin-and-sleeve contacts in connectors.

Pin-and-Sleeve Contact Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time on pin-and-sleeve contacts.

Compression Lug and Splice Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Compression Lug and Splice Crimpers

Hydraulic Compression Lug and Splice Crimpers

The most crimping force we offer—these tools have a high-pressure pumping system.

Battery Terminal Hammer-On Crimpers

A compact and economical alternative to standard battery terminal crimpers. Hammer the top of the pin to crimp.

Battery Terminal Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Battery Terminal Crimpers

The rotating dies in these crimpers are coded to match battery cable and terminals, making it easier to select the correct die.

Combination Electrical Wire Strippers and Crimpers

Strip wire and crimp connectors with one tool.

Squeeze-and-Strip Combination
Electrical Wire Strippers and Crimpers

One squeeze strips insulation and pulls it off the wire.

High-Voltage Combination Electrical
Wire Strippers and Crimpers

The rubber grip provides protection up to 1,000 volts AC.

Data and Coaxial Cable Strippers, Crimpers, and Tools

Coaxial Cable Crimpers

Coaxial Cable Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Confined-Space Coaxial Cable Crimpers

The elongated nose on this tool reaches into tight spaces.

Ethernet Cable Ratchet Crimpers

The ratchet applies the correct pressure to ensure a complete crimp every time.

Ethernet Cable Crimpers

Terminal and Splice Assortments

Use the included crimping tool to install a variety of terminals and butt splices.

Electrical Connectors

Stackable Pin-to-Pin Connectors

Also known as power-pole connectors, these single-pole connectors join two pin connections, rather than a pin and socket. They stack from the top and sides to form any configuration.

Build-Your-Own Molex Compact Connectors

Configure a connector for your application—combine housings with pins and sleeves for different wire sizes. Use them with standard Molex connectors.

Build-Your-Own AMP Compact Connectors

Configure a connector for your application—combine housings with pins and sleeves for different wire sizes. They fit AMP MATE-N-LOK connectors.

Deutsch-Style DC Connectors

Use these connectors in vehicles and other agricultural and construction equipment. They have a sealed nylon housing that resists dust and temporary submersion.

Build-Your-Own Weatherproof DC Connectors

Configure a connector for your application by combining housings with pins and sleeves for different wire sizes. Also known as weather-pack connectors, they withstand moisture, harsh engine fluids, and high temperatures.

Weatherproof DC Connector Sets

Each set includes one plug and one socket. These connectors withstand moisture, harsh engine fluids, and high temperatures. Also known as weather-pack connectors.

Mil. Spec. Compatible Connectors

These connectors have the same pin and socket configuration as connectors that meet MIL-DTL-26482, so they can be used with products that meet the same standard. Quickly mate them by pushing them together.

Vibration-Resistant High-Current Connectors

Make secure connections with machine tools, robots, and other equipment that vibrates frequently and carries currents as high as 300 amps.

Servomotor M23 Connectors

These general purpose M23 connectors send power or signal to servomotors, servocontrollers, and servodrives.

Multipurpose Build-Your-Own Latching Connectors

Assemble a connector that can handle multiple applications at once. Combine inserts that send power, signal, and data with a base and a hood.

Build-Your-Own Latching Connectors

Configure a connector for your application—combine inserts for power and signal with a base and a hood.

Compact Latching Connectors

The smallest latching connectors we offer, these fit in tight spaces. The base and hood latch together securely, yet can be quickly detached for equipment repair or replacement.

Data, Audio, and Video Connectors

Shielded Easy-Install Crimp-On Data Connectors

Protect sensitive equipment from electromagnetic interference.

Unshielded Easy-Install Crimp-On Data Connectors

Pull wires all the way through the connector face, and then use the crimper to cut and crimp wires in one step.

Push-to-Lock Data Connectors

Push these connectors together for secure Ethernet connections that are quick and easy to connect and disconnect with just one hand. You’ll know when the plug and socket are locked in place when you hear a click.

Unshielded Crimp-On Data Connectors

Use an Ethernet cable crimper to terminate these plugs.

Shielded Crimp-On Data Connectors

Protect sensitive equipment from electromagnetic interference.

Coaxial Connectors

Transmit audio, video, and data through coaxial cable.

D-Sub Connectors

Assemble DB and HD connectors to replace worn out connectors.

Screw-Together Wet-Location
RJ45 Connectors and Cords

Use these connectors and cords to make Ethernet connections in wet location environments.
