328pcs Heat Shrink Tubing Assortment Kit (8 Sizes)

If you have a lot of wiring to do, you need more than just insulation—you need organization. This 328-piece kit includes heat shrink tubing in distinct colors, allowing you to color-code your power lines (Red), ground wires (Black), and signal wires (Blue/Yellow). It covers a huge range of sizes, from tiny 1mm tubes for repairing headphone cables to large 14mm tubes for thick battery cables. The tubes shrink to half their diameter (2:1 ratio) when heated, creating a tight, waterproof seal.
