<p ><strong>Specification: </strong><strong> </strong><br> Shrinkage ratio is 2:1  <br> Temperature that start to shrink: 80℃  <br> Temperature that solder ring start to melt: 111˚C <br> Temperature that solder ring melt completely：138˚C <br> <strong>Note: </strong>It means the temperature of surface of the connector, rather than the temperature that the hot air gun should set. </p> <p ><strong>How to use: </strong><strong> </strong><br> 1.Strip the two wires that going to connect and select the right size of connector. <br> 2.Thread the connector to one of the wires and then twist the two conductor together. <br> 3.Move the connector to the middle of the conductor. <br> 4.Apply heat to the connector slowly and evenly with a hot air gun with nozzle until it melt with the wire. </p> <p ><strong>Note: </strong><strong> </strong></p> <ol> <li>Some of our customers can use lighter to finish the joint, but we recommend that it is better to use a heat gun with nozzle to heat shrink the connector. </li> <li>Please rotate the wire when you are heating or surround the wire to heat so that the tube was heated evenly. </li> <li>3-5 cm (1.18-1.96 inch) is the suitable distance we recommend from the nozzle to the connectors. </li> </ol> <p ><strong>Package Include: </strong><strong> </strong><br> 1.30 x White Connectors: Diameter 1.7 mm, able cross-section 0.25-0.34 mm²(A.W.G.:26-24);  <br> 2.40 x Red Connectors: Diameter 2.7 mm, Cable cross-section 0.5-1.0 mm²(A.W.G.:22-18);  <br> 3.40 x Blue Connectors: Diameter 4.5 mm, Cable cross-section 1.5-2.5 mm²(A.W.G.:16-14);  <br> 4.10 x Yellow Connectors: Diameter 6.0 mm, Cable cross-section 4.0-6.0 mm²(A.W.G.:12-10). </p>
