Heatshrink Tubing

Heatshrink tubing is the ideal way to create a tight, professional finish on any wire, hose or cable management project.

Once shrunk, the tubing will hold its reduced state even in elevated temperatures. The wide range of available colors and diameters makes Techflex Heatshrink Tubing a perfect solution for any termination application.

Measure the heatshrink tubing to length and cut with a scissor. The thickness of your bundle, as well as the desired final appearance, will determine the length of the tubing you cut. Generally, a piece 1 1/2” - 2” long will accommodate almost any need (such as this bundle of 10 CAT-5 network cables). Single wires, or smaller bundles, require shorter pieces.

Slip the tubing over the bundle and position it so that both the sleeved and unsleeved portions are sufficiently covered. Notice the small pieces of tubing installed on single wires as part of a color coding system. If your project requires multiple operations, always work up from the smallest to the largest bundle.

Gently apply heat from a heat gun, hair dryer or torch with an appropriate attachment. Keep the heat source far enough away so that hot metal or direct flame don’t come in contact with the tubing, wires or sleeving. Move the heat around the bundle to prevent damaging the sleeving and to ensure that all areas of the tubing have been shrunk. Once cooled, your installation is complete.
