Whether you’re an avid DIYer or a professional contractor, you need to fix wires frequently for a secure electrical connection. Some people prefer fixing wires and terminals on their own because calling a professional electrician to secure the wires can be costly, even if it’s a small task. You can easily make these small fixes yourself by using a heavy-duty crimping tool.
A crimping tool creates a tight seal on your wires using terminals to secure them in place, protecting them from moisture and dust. But with an array of crimpers available on the market, finding the right product that matches your needs can be challenging. We have rated and reviewed some top crimping tools of 2023 to make your DIY projects hassle-free.
You should first check the wire size that your crimping tool can support. This is because it gives you an idea about the type of wires you can crimp in terms of their thickness and diameter.
Wires generally come with a thickness rating expressed as American Wire Gauge (AWG) and most models range from 12 to 24 AWG. So, you should pick a versatile tool that you can count on for crimping wires of any size.
If you are a professional contractor who often has to crimp wires of different sizes, you should get a crimping tool with different cavities. In other words, a crimper with multiple cavities can help you crimp wires of different thickness ratings without having to switch between different crimping pliers.
How To Use a Crimping Tool
Remove wire casing
The first step is to remove the rubber casing on your wire. Make sure to not cut it all the way through, or you might damage the copper inside. Instead, just make an even cut around the wire and slip the casing off. Once the copper is exposed, you’ll be ready for the next step.
Add the connector
There are plenty of connectors to choose from, such as an open barrel connector. With this type of connector, you can easily lay the wire inside before you crimp it. Then, use the ratcheting mechanism on your crimping tool to help you place the connector in the right-sized spot inside the jaws. Afterward, you can use the star wheel to adjust the force depending on how tight you want the crimp to be. The tighter you crimp your wires, the less likely they are to come apart over time.
Crimp the wire
Then you insert the wire into the connector and simply press the handle to crimp it, pressing them together easily. With some crimping tools, this might require a bit of force, but it’s the best way to get the job done. If you feel like the placement is wrong, you can use the quick-release button to open up the jaws before the crimp is complete.
Once this step is done, you’ll have a neatly crimped wire.
Why You Need a Wire Crimper
Crimping wires is a great way to keep them protected from dust and sand, which can make your wires last longer. It is also a less messy process than soldering and fairly easy as well. With the help of a crimping tool, you won’t need anyone else to get a neatly crimped wire at home.

People Also Asked
Q: Should I solder my crimp after it’s done?
No! There’s no real need to solder or even use heat compression on your crimp after it’s done. This is because most crimping tools are reliable enough to create a tight seal on the wire by pressing it into the connector.
Q: Why is there color coding on my crimping tool?
Some crimping tools are color coded to help you pick the right wire size for each terminal, so you can quickly identify the needed crimper from a distance without having to juggle tools.
Q: Why should I opt for crimping rather than soldering?
Crimping offers a stronger, more reliable connection when compared to soldering. The main difference is that soldering uses heated metals to connect wires to the connector and this metal might degrade over time. Plus, soldering is much easier than crimping.
