12.7 mm 3:1 Adhesive-Lined Dual-Wall Heat Shrink Tubing, Black

Black 3:1 adhesive-lined dual-wall heat shrink tubing in the nominal 12.7 mm size. The PE outer wall shrinks with heat, while the inner adhesive softens around the wiring. Use for wire insulation, cable-joint repair and terminal protection.

Choose the supply configuration

Select a 1 m or 10 m cut length, or an original whole-roll option where listed. Each whole-roll option supplies one roll of its stated length. Small-roll and standard-roll labels identify the corresponding supply presentation.

Supplier reference dimensions

The nominal size is the supplier size designation. Use the separate reference bore values when choosing tubing. Values are supplier reference data. Check clearance over the widest part of the connection and the required recovered fit.

Packing quantities shown in the supplier reference chart describe bulk packaging. Your order follows the selected cut-length or whole-roll option.

Installation

Cut a section to suit the joint, slide it onto the wire before joining, then center it over the completed connection. Apply heat evenly with a suitable heat gun. Allow the tubing and adhesive to cool before handling.

What is included

Black tubing in the selected nominal size, supplied as one cut length or one original roll exactly as listed in the option. Coil and spool photographs are supplier series references. Wires, terminals, tools and other installation props are supplied separately.

Selection questions

Does the nominal size equal the starting bore? The nominal designation and supplier reference bore are listed separately above.

What is a cut length? It is one 1 m or 10 m section of tubing. Select an explicitly listed whole-roll option when you need that original roll configuration.
