Thermal insulation set 530 pieces Chinese

The heat shrink tube is available in all sizes required for professional maintenance and DIY home projects, especially the smaller sizes that are uncommon in the market. All heat shrink tubes are packed in a plastic box for easy carrying so you don't have to worry about mixing tubes of different sizes. The specifications for all tube sizes are shown on the plastic box for easy identification and access. Suitable for electrical insulation, wiring assembly, color coding, mechanical protection, wire/cable joints, daily repairs, and so on. Easy to use, cover the exposed part of the wire with these tubes, heat with a soldering iron, hot glue gun, or even a hairdryer (hot enough), and the tube will shrink to protect the wires and give you a professional look for the repair job!
