What are Hydraulic crimping tools and their applications?

by Carter Toni

Hydraulic Crimping Tools:

These tools are fundamentally specialized pliers designed to fold and crush metals like copper and aluminum in numerous forms. We can crimp a metal object to squeeze it into a joint or into closure that is so tight it will not re-open on its own. Crimping can be an actual way to conjoin 2 pieces of metal, such as conferring a connector to the end of a cable, by re-shaping it to hold them together. Hydraulic crimping tools can be used on cable wiring, electric cables, and other types of wires. Many people like to use hydraulic crimping tools over other tools with alike applications because they are usually portable and do not take up a lot of storing space. Some find them more real and easier to use than alike tools like hammer crimps or physical crimping tools, and, dependent on the type of hydraulic crimping tool, they can be more versatile. They are especially useful to have on hand if we are dealing with larger wires or cables, as they are more powerful than their physical counterparts and make crisper and sharper corners.

What to Look in a Hydraulic Crimping Tool


For such a tool that seems as simple as hydraulic crimping tools, there is some difference to be found in these tools. A crimper that works well on, the copper wire may not necessarily work as well on wires made of a dissimilar kind of metal. Some types of hydraulic crimpers may work improved for welding or electric cables than others. We should be sure to check the images of any hydraulic crimping tool we want to buy to make sure it is compatible with the task.


Dies are the substitutable jaws of a crimping tool, the parts that touch and form the metal. The quality, form, size, and number of dies comprised with a hydraulic crimping tool will differ depending on the tool itself and the company that makes it. It is necessary to look for tools that have to die made of tough material, as they will be on the getting end of most of the wear and tear during the usage.


The strength of a hydraulic crimping tool is measured in tons and can also vary considerably. The thicker and rougher the metal we are working with, the more force we will need from your hydraulic crimping tool. 5 – 8 tons is a pretty standard level of force and so if we are going to use the tool on a tougher metal like aluminum or steel, we will want to buy a crimper that’s in the 12 – 16 ton range.
