how to heat shrink connectors

Best answer


Slowly spin the connector(holding the wire about 4 to 6 inches away) as you apply heat,starting at the farthest point from the open end and working toward it to force air out and prevent trapping air bubbles inside the collar. Once the shrinks are tight,remove the heat and allow the connector to cool before touching it.

  • How do heat shrink tubing connectors work?

  • They consist of an outer layer of heat shrink tubing with a section of solder on the inside. When heat is applied, the solder melts and forms a solder joint on the wires inside the connector.

  • What are heat-shrink electrical connectors?

  • As their name implies, heat-shrink electrical connectors have insulation that shrinks when heat is applied. Most also have an adhesive inside the insulation that seals tightly against the wire to help to make the connection weather-resistant, which in turn helps prevent corrosion.

  • What are heat shrink Butt connectors used for?
