10 cm heat shrink

This product is a set of heat-shrink tubing used to insulate and protect cables and electrical connections. With lengths of 10 cm and varying inner diameters, it fits different cable sizes. The kits include multiple diameters and colors to provide effective insulation and better organization of your wiring. This polyolefin solution offers long-lasting insulation and resistance suitable for both home and professional use.

Measure your cable or connector diameter, then select a tube whose inner diameter is slightly larger for a secure fit—while also respecting the shrink ratio. For example, 7 mmID versions are suitable for thinner cables, while sizes like 12 mmID fit wider sections. The typical shrink ratio is 2:1, meaning the final diameter will be about half the original diameter.

Kits offer inner diameters from 3 to 12 mm depending on the model, and include various colors such as black, blue, green, red, white, and yellow. This variety helps you insulate and organize multiple cables using color-coded identification. Some sets also include multiple 10 cm lengths and a large number of pieces, so you can outfit many cables and electronics or household projects.

The polyolefin material supports reasonable temperatures for insulation and shrinking. The time and shrink temperature vary by diameter, but the specification sheets generally list a usable range that covers common home and professional conditions. Expect faster shrinking once the tubing is heated, which improves insulation and helps secure connections.

Cut a piece slightly longer than the section to be protected, insert the cable, then heat it using a hot air gun or an iron under an appropriate setup until the tubing retracts tightly around the cable. After that, check for wrinkles and make sure the tubing is evenly fitted along the entire length. Proper installation ensures effective insulation and protection.

Store the kits in a dry place away from intense heat sources when not in use. During installation, wear gloves and follow the manufacturer’s instructions to avoid burns or thermal damage. After installation, periodically check the tubing for cracks or peeling and replace it if needed. Use the correct diameter and avoid overheating, which could damage cables or the tubing.
