6 types of crimpers and how to use them
THE BOOTLACE HERO
The Maun Bootlace Ferrule Crimper is a compact tool does what it says on the tin - crimps bootlace ferrules or bootlace crimps to wires. Bootlace ferrules are metal tubes with a colour-coded insulation collar, typically made of plastic or nylon.
Handy when using screw terminals to prevent multiple core wires from splitting, this gadget is a maintenance and electrical installation favourite.
How to crimp with this tool:
1.Firstly, strip the insulation off the section of your wire that will slot into the connector.
2.Slip the wire into the connector, then place the connector in the crimper jaws.
3.Apply force to the handles, securing the connector around the wire. If you aren’t happy with the crimping security, reinsert the connector and clamp again to apply more pressure.

THE COAXIAL SPECIALIST
These Maun crimping tools belong in the toolkit of every professional electrician and television or radio aerial service engineer. The crimpers feature colour-coded handles to help you use the right tool for the coaxial impedance in question. Choose between a 75 Ω connector Crimping Tool for RG 59 cable and a 50 Ω connector Crimping Tool for RG 58 coaxial.
Both tools include a ratchet release lever, which only releases once crimped enough for maximum safety.
How to use these crimping pliers for coaxial cables:
1. Feed the crimping ferrule or sleeve over and down your wire, ready to slide back up later.
2. Prep your wires, following your connector instructions. Typically, you’ll trim back around 20 mm of insulation, 10 mm of wire braiding and 5 mm of inner insulation to reveal the centre conductor, showing all four materials at once. You might need to trim these further as you go.
3. Slot the wire’s newly revealed centre conductor into the connector’s centre pin, and clamp inside the crimping tool’s small cavity until the ratchet is released.
4. Flair the braided wire shield for easier insertion of the connector body.
5. Now insert the newly crimped wire and pin into the connector body. Make sure the connector slots neatly under the cable’s braiding but over the inner insulation, parting the two materials.
6. Once your braiding is around the connector, feed the crimping ferrule or sleeve over the two until it hits the connector’s body.
7. Now place the crimping ferrule or sleeve into the crimping tool’s larger cavity and close the handles until the ratchet is released.
