Features 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 Package List 40 x 1.5x45mm Yellow Tube 40 x 2.0x45mm Blue Tube 40 x 2.0x45mm Black Tube 30 x 3.0x45mm Green Tube 25 x 4.0x45mm Red Tube 25 x 4.0x45mm Black Tube 20 x 5.0x45mm Black Tube 20 x 6.0x45mm Yellow Tube 10 x 8.0x45mm Red Tube 10 x 10.0x45mm Green Tube 10 x 10.0x45mm Blue Tube 10 x 10.0x45mm Black Tube 1 x Storage Box
