Feature: 1. Made of high-quality insulating materials, water and electricity isolation, high strength and toughness, and can be bent arbitrarily after heat shrinking. 2. The heat-shrinkable tube will shrink when heated, the internal solidified glue will melt, and the wiring will be tight and waterproof. 3. Use a lighter or a hot air gun to quickly shrink after heating, which is very convenient to use. 4. The PC box adopts a freely partitioned design, which is convenient to take the required size and is convenient for sorting and storing. 5. Widely used in wire connection, solder joint protection, wiring harness identification, insulation protection of resistance and capacitance, etc. Specification: Item Type: Heat Shrink Tube Material: Nylon, PC Uses: Electronic components, circuit wiring harness, wire connection repair, data line (small head) repair, household goods line repair.
