Cable trunking and insulation

The kit provides eight inner diameters to fit a wide range of wires: 1.0 mm, 2.0 mm, 3.0 mm, 4.0 mm, 6.0 mm, 8.0 mm, 10.0 mm, and 14.0 mm. This variety allows you to insulation-wrap small signal wires up to thicker power cables. The assortment makes it easy to tailor each sleeve to the exact cable diameter for a snug, protective fit.

Use them for cable insulation, split wire repair, and bundling multiple wires together for neater installations. These sleeves are designed for electronics and electrical projects, with the durability to protect wires from abrasion and moisture in everyday electronics, home repairs, and car or appliance maintenance.

Colors include black, blue, green, red, and yellow, which helps you color-code different circuits or projects. Color-coding improves organization in multi-cable setups and makes it easier to identify wires during maintenance or upgrades, keeping installations tidy and safer.

Cut the tubing to the required length, slide it over the wire or joint, and apply heat with a heat gun or a hair dryer until the sleeve tightens and seals. The tubing then provides insulation, mechanical protection, and strain relief, helping prevent moisture ingress and wear at connection points.

Yes. These heat-shrink options are versatile enough for electronics, automotive wiring, computer setups, and household repairs. They offer robust insulation and protection, making them suitable for repairing cables in cars, appliances, and home-office setups.

Besides diameter range, consider the total piece count (164 pieces in this set), the number of colors, and the ease of storage. A larger assortment with distinct colors and multiple sizes accelerates your projects by letting you pick precisely sized sleeves for each cable and keeping tools organized for future jobs.
