Our Raychem heat shrink tubing provides electrical insulation, mechanical protection, environmental sealing, and strain relief for applications such as back-end connector sealing, breakouts, and connector-to-cable transitions. It is a solid alternative to taping, molding or potting. When heated, it conforms to the size and shape of the substrate beneath, enabling quick and easy installation. Its high expansion ratio makes it possible to repair most damaged cable jackets without removing connectors. Available in a wide range of materials, colors, and sizes, heat shrink tubing is delivered in forms such as spools, 1.2m lengths, and cut pieces. Clear types permit inspection of covered components and offer excellent transmittance of light.
