  • Nylon insulated splice or butt connector.
  • Heat shrink butt connector and
  • High-temperature butt connector.

How to connect two wires using a butt connector?

These are the exact methods you should be following while connecting two wires for any given purpose with the help of a butt connector.

  • The first thing you should consider while connecting two wires is that you need the right sized connector with the right sized wire. If the connector and wire are not compatible with each other, you will not be able to get a smooth connection.
  • With the help of a crimping tool, strip the wire out according to the right measurement.
  • Push the wire directly into the middle portion of the butt connector and crimp the middle of the butt connector a little bit with the help of the crimping tool.
  • Do the same for the other part of the butt connector.
  • Finally, you need to heat the butt connector up for a convenient connection. Make sure you are using a heat gun to do so instead of a gaslighter.

That’s it! That is how you should be installing two wires into a butt connector to have a superior and convenient connection, avoiding any kind of short circuit.
