Operating temperature: -55°C- 125°C Shrinkage temperature: 80℃- 130℃ Note： 1. Use a heat gun or lighter to shrink the tube. Keep approximately 1/2 inch away from the tube when using a lighter to shrink the tube, otherwise, a black mark may be left on the tube. Do not touch the tube until it has cooled completely. 2. Keep the hot air gun at the proper distance and rotate the connector for even heating. 3. Do not set a high temperature at the beginning, otherwise, the connector surface will overheat, which will cause the tube to melt while the weld ring remains unmelted. 4. This product includes only 560PCs coloured heat shrink tube & 140PCs solder wire connectors set, without other decorations. 5. This product comes as a mix of various items, the quantity of each item may not be exact due to the manual count. 6.
