750Pcs 2:1 Heat Shrink Tubing Kit Electrical Wire Cable Wrap Assortment Electric Insulation Heat Shrink Tube Kit with Box 5 Colors and 12 Sizes for Electronic Components

The 750Pcs 2:1 Heat Shrink Tubing Kit Electrical Wire Cable Wrap Assortment Electric Insulation Heat Shrink Tube Kit with Box 5 Colors and 12 Sizes for Electronic Components is one of those supplies you don't think about until you need it — and then you're glad you have it. This assortment covers the common sizes used in electronics, automotive, and hobby wiring projects.

Material quality is solid. The polyolefin tubing shrinks evenly when heated, conforming tightly around wires and solder joints. The 2:1 shrink ratio is standard and works well for most single-wire insulation tasks. A heat gun gives the best results, though a lighter works in a pinch for small pieces.

The size assortment is well thought out, covering diameters from small signal wires up to thicker power cables. Having multiple sizes on hand means you can insulate anything from a single solder joint to a multi-wire bundle.

For the price, this is a staple supply item. Every electronics bench, tool box, and field repair kit should have a set of heat shrink tubing ready to go. It beats electrical tape for durability and appearance every time.
