FAQs
Can I use these pliers for insulated terminals?
No, these pliers are specifically designed for non-insulated open barrel terminals only. Using them on insulated terminals may result in a poor connection or damage to the tool.
What is the wire gauge range for this tool?
The tool is suitable for wire gauges from 14 AWG down to 24 AWG, which corresponds to approximately 0.45mm to 2.5mm.
What types of terminals can I crimp with this tool?
This tool is designed for Deutsch, electronic sensor, and Weatherpack open barrel terminals.
How do I ensure a good crimp?
Select the correct groove for your wire size, seat the terminal properly, and apply firm, consistent pressure. The crimp should be secure and the wire should not pull out.
Are these pliers suitable for marine applications?
While designed for automotive, they can be used for marine applications if those applications utilize Deutsch, electronic sensor, or Weatherpack style terminals and require non-insulated connections.
What is the length and weight of the pliers?
The pliers have a length of 210mm and a weight of 300g.
Troubleshooting
Crimped terminal is loose or pulls off.
Ensure you are using the correct groove for the wire gauge and terminal size. Verify the terminal is fully seated in the pliers before crimping. Re-crimp if necessary, ensuring firm pressure.
Pliers feel stiff or difficult to operate.
Clean the pivot point and apply a small amount of light machine oil. Check for any debris lodged in the jaws or mechanism.
Wire strands are cut or damaged during crimping.
Ensure the wire is properly stripped and seated within the terminal barrel. Use the correct crimp setting for the wire gauge; over-crimping can damage conductors.
Jaws do not align properly.
Inspect the jaws for any damage or bent tips. If damage is present, the tool may need replacement. Ensure the pivot is clean and lubricated.
