Electric tube

Direct answer: Choose the diameters and shrink ratios that match your wire space and your insulation goals. This collection offers various options, including tubes with inner diameters of 3 mm, 6 mm, 7 mm, and 10 mm, in lengths of 1 m, 5 m, or even 10 m. You’ll also find multiple colors such as blue, black, and yellow, and some larger bundles include up to 164 pieces. Choose what fits your insulation and protection needs from moisture and friction.

The main factor is the insulation diameter your cable or wires need, taking into account the 2:1 shrink ratio in some products. Different lengths—like 1 m and 5 m—help with coverage for different home or industrial projects. Colors and materials such as polyolefin provide insulation performance and durability, while having a fire-resistant layer improves safety. Also look at manufacturing quality and warranty availability—some bundles may include a one-year warranty.

The key feature centers on polyolefin material, responsible for effective electrical insulation, with water- and moisture-resistant properties and heat tolerance up to about 125°C continuously. The options include multiple colors and large bags with up to 164 pieces for bigger bundles. Some models also handle heat well and provide reliable insulation for electricity and vehicles. In some models, a flame-resistant layer improves safety.

Most offers in this collection allow a one-year warranty on the products, with some exceptions that may state they come without warranty. This means you get protection with the kit you choose—especially when the tubes are intended for small electrical projects or home use. Check the seller page before purchasing to confirm warranty terms, the duration included, and replacement details in case of a manufacturing defect.

For beginners, we recommend the 164-piece bundle, which includes a wide range of diameters, lengths, and materials—giving you coverage for different applications from basic insulation to protecting more complex wiring. If you need something more tailored, choose 5-meter lengths for larger needs or 3–6 mm diameters for DIY projects and home maintenance. These options support multi-use and reduce the need to buy extra pieces.
