What are bootlace ferrule crimpers?

Bootlace ferrule crimpers are designed to crimp bootlace ferrules.

Bootlace ferrules are copper tubes that are used to create a reliable electrical connection at the end of an electrical wire. They're used to protect the copper wire, when connecting the ends of a cable to an endpoint. They come in two different types, insulated and uninsulated. Insulated ferrules come with a recognisable coloured insulation sleeve, whereas uninsulated ferrules don't have a sleeve. Insulated ferrules also come in two different sizes, Single or Twin versions. Single ferrules are used to insert a single cable, whereas Twin ferrules are used to bundle two cable ends into one.

Crimping is the process of joining two or more fittings together by deforming one or both pieces. crimping pliers, therefore, help to join the copper cable end with the ferrule, creating a reliable connection.

How to choose bootlace ferrule crimpers?

When shopping for bootlace ferrule crimpers, look out for the following important features:

  • Adjustable for Different Sizes – you'll need to crimp a whole range of different sized ferrules, so you need one tool that can handle all the popular sizes.
  • Hardened Jaws – your tool is no good if it stops working after a short period of use, so choose a crimper that has HRC 57 hardened jaws for extra durability.
  • Hand Force Multiplier – crimping is hard on the hands, so you want a tool that will multiply your hand force to make it easier. Look for a tool providing a 12x multiplier.
  • Return Spring – resetting the tool while crimping, particularly if your hands are full, can be really awkward. So choose a tool with a return spring, so you don't have to.

How do you crimp a bootlace ferrule?

To crimp a bootlace ferrule with crimping pliers, follow these steps:

1. Strip the end of your cable to reveal the copper insides.

2. Slide the copper ends gently into the bootlace ferrule, until the ends almost reach the other end.

3. Clasp your crimpers around the non-coloured part of the ferrule and press down firmly until you have created a secure connection.

Can you crimp ferrules with pliers?

You can try to use a set of pliers to crimp when in a pinch, but you won't get a good quality crimp, and so you may end up letting moisture into the connection, which can cause corrosion.
