? Features ? ? Shrinkage Ratio 3:1 ? An easy One-Step Wire Connections. ? Easy Identification: Color coded connector tubing. ? Polyolefin heat shrink butt connectors improve Pullout Strength. ? High-quality wire connectors in Seal, Strain Relief, Cable Check and Insulation. ? Melted Solder ensures wires Strongly Connected and avoids wires slipping out from the terminal. ? Operating temperature range ? ? Operating temperature : -55??125? ? Minimum shrink temperature : 80?C ? Minimum temperature for solder to melt: 138°C ? Package Included ? ? 10 x White Connectors: Suits Cable/ Wire Sizes 0.25-0.34mm² (A.W.G:26-24); ? 22 x Red Connectors: Suits cable/ wire sizes 0.5-1.0mm² (A.W.G:22-18); ? 10 x Blue Connectors: Suits cable/ wire sizes 1.5-2.5mm² (A.W.G:16-14); ? 8 x Yellow Connectors: Suits cable/ wire sizes 4.0-6.0mm² (A.W.G:12-10) ? 1 x PP Storage Case ? HOW TO USE ? ? Select the proper size connector for the wires, stripped wires. Insert the stripped wires into the connector. ? Apply heat evenly to the connector from the 2 ends first until tubing shrinks and the adhesive flows, then continuously apply heat evenly until solder sleeve melt and seal. ? WARM TIPS ? ? For better results, continuously rotate the connector when applying heat with a HEAT GUN to make the terminal evenly heated. ? Keep the hot air gun a distance of 3-5 cm to the solder connector when the connector is being heated. DO NOT get too close. ? DO NOT set high temperature at the beginning, or the surface of connector will be over-heated, which will cause the tube melt to damage but the solder ring still not melt.
