WKK Heat Shrink Tubing Assortment Black 465 pcs 2:1 (28113101)

Electrical wiring projects often require reliable insulation and protection for splices, terminals, and cable bundles. This heat shrink tubing assortment provides a comprehensive solution with 465 pieces in ten different diameters, all in black. The tubing shrinks to half its original diameter when heated, creating a tight, protective seal around wires and connectors. Made from polyolefin, it offers good electrical insulation and resistance to abrasion and chemicals. The pieces are pre-cut to 45 mm lengths, ready to use. A reusable storage box keeps the assortment organized and accessible.
