Use this heat shrink tubing kit from RS PRO to attach labels to your electrical wires. It's supplied with four different versions of clear tubing and is suitable to use in demanding industrial applications.
The plastic covers attach easily with the help of a heat gun to form a firm seal over your wire. Various types of tubing allow the sleeves to be used with a wide range of operating temperatures, so you can choose the component that best suits your application. Some of the units are halogen-free meaning they won't release any toxic gases when heated.
Most of the sleeves in this kit meet SAE-AMS-DTL-23053-13 standards for safe electrical insulation. For additional peace of mind, they're made from Viton fluoroelastomer – a thin-wall, heat-shrink tubing that's flexible, flame-retardant and abrasion-resistant.
