  • You need a good wire stripping tool, and a reliable heat gun or lighter for melting the solder and shrinking the tubing.

  • Shrinkage ratio 2:1.
  • Waterproof Rating: IP67.
  • Material: Polyolefin Tubing with Solder and hot melt adhesive Inside.
  • Minimum temperature for solder to melt: 280°F / 138°C

  • Minimum shrink temperature: 176°F / 80°C

  • Please raise the temperature from low to high gradually when you use the hot air gun to heat the wire connector.
  • Please DO NOT set the high temperature at the beginning, or the surface of connector will be over-heated, which will lead to the tube melt while the solder ring still not melt.
