Feature: 1. These heat‑shrinkable tubes are made of nylon, water and electricity are not flammable, and no tape is required. 2. These tubes shrink when heated, and the internal solidified glue melts, and the wiring is tight and waterproof. 3. With high strength and toughness, it can be bent arbitrarily after heat shrinking, and the tensile strength is good. 4. Use a lighter or a hot air gun to quickly shrink after heating, which is very convenient to use. 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 Uses: Electronic components, circuit wiring harness, wire connection repair, data line (small head) repair, household goods line repair Heat Shrinkage Ratio: 2: 1 Include Size: Yellow: Approx. 1.5 x 45mm / 0.1 x 1.8in, 6 x 45mm / 0.2 x 1.8in Blue: Approx. 2 x 45mm / 0.1 x 1.8in, 10 x 45mm / 0.4 x 1.8in Black: Approx. 2 x 45mm / 0.1 x 1.8in, 4 x 45mm / 0.2 x 1.8in, 5 x 45mm / 0.2 x 1.8in, 10 x 45mm / 0.4 x 1.8in Red: Approx. 4 x 45mm / 0.2 x 1.8in, 8 x 45mm / 0.3 x 1.8in Green: Approx. 3 x 45mm / 0.1 x 1.8in, 10 x 45mm / 0.4 x 1.8in.
