Item Type: Heat Shrink Tube Material: Nylon, tin Uses: Industrial production, electrical circuits Wiring Range: SST-S41 (yellow): 4-6mm2 SST-S31 (blue): 1.5- 2.5mm2 SST-S21 (red): 0.5- 1.5mm2 SST-S11 (white): 0.25- 0.34mm2 Stripping Length: Approx. 10mm / 0.4in Working Temperature: -55-125 Start Shrinking Temperature: 80 The Temperature at Which the Solder Begins to Dissolve: 138 Complete Melting Temperature of Solder: 160 Shrinking Temperature: >160 Dielectric Strength: 1KW Protection Level: IP67 How e: 1. Get ready to strip the wires 2. The casing is inserted and the wires are connected 3. Heat it with a heat gun 4. Make it shrink and set1Good abrasion resistance and environmental protection, specially designed for harsh environments, to provide protection for wires and cables 2In the case of preventing abrasion, cutting, abrasion and low impact, it creates a cable entry seal and provides environmental seal protection 3Advanced solder seal ring, enough solder to melt and flow around the wire until a seal is formed on the wire, ensuring a lasting connection 4Good weather resistance, the adhesive provided by the right amount of hot melt adhesive system, cools, hardens, and reaches the bonding strength within a few seconds, giving a lasting bond 5Quick to operate, only a heat gun is needed to fix and connect the wires tightly. 50 xHeat Shrink Tube
