The main reason to use a wire ferrule is to prevent the wires from fraying or fanning out, which is a common problem when using stranded wire. Wire ferrules are cylindrical in shape and made of a tin plated copper. They are available with a nylon extruded jacket or non insulated.

In the first picture you can see a single strand of wire that has separated from the group of stranded wires. Occasionally this can happen during the installation process. This loose strand can cause a possible intermittent failure in the electrical system and these types of failures are more difficult to locate and can be very expensive to isolate and repair. Using a wire ferrule can turn a stranded wire with into a solid wire, which will in the end save you time & money.


They are also ideal for use in any application where you may need to insert & remove the wire numerous times, they will protect the wire from becoming frayed and unmanageable over time.

A wire ferrule can also ensure that you get 100% conductivity when inserting your terminated wire into the connection you are working with. For example- a terminal block or trailer receptacle and plug with pressure plated setscrews.


Here are a few other products that may come in handy:

Dielectric Grease

Dielectric grease is a non-conductive, silicone-based grease that’s designed to seal out dirt, moisture & prevent corrosion on electrical connectors & wiring. Click here to see more about what we offer.


Wire Strippers

The first step when using a wire ferrule is always stripping the insulating jacket to expose the inner strands of the wire.  Wire strippers come in many different varieties- self adjusting, spring loaded & compact to name just a few, but the one thing you need to look for is that it will work with the wire gauges you’re using. Click here to see more about what we offer.
