Heat shrink tubing Cabletech 8 mm × 1 m, red, model LEC-NAR0260.1

Heat shrink tubing Cabletech 8 mm × 1 m in red is a single-length polyolefin sleeve designed to shrink when heated, providing reliable electrical insulation, mechanical protection and strain relief for cable joints and terminations. The 8 mm diameter before shrinkage and 1 m length make this sleeve suitable for a range of wiring tasks where color-coding and durable protection are required. The red color allows easy identification of circuits or components in installations.

Advantages

This heat shrink tubing offers consistent shrink performance and good dielectric properties typical of polyolefin materials, enabling safer and neater cable repairs and terminations. Its single continuous length simplifies cutting to the exact size needed for a repair or insulation task. The tubing resists abrasion and provides a degree of moisture protection and mechanical reinforcement at connection points.

Suitable for

• Insulating and protecting splices, solder joints and terminal connections
• Color-coding wires and cable harnesses in automotive or electronic systems
• Repairing damaged outer cable insulation and providing strain relief
• Organizing and bundling small cable runs

Key specifications

• Material: polyolefin heat-shrinkable tubing
• Nominal diameter before shrink: 8 mm
• Length: 1 m (single continuous sleeve)
• Color: red
• Shrink ratio: typical for standard polyolefin (provides tight fit after heating)
• Primary functions: electrical insulation, mechanical protection, strain relief, color identification

How to use

Measure and cut a length of the tubing that will fully cover the splice or connector with some overlap on either side. Slide the tubing over the joint or component before making the final connection when possible, or position it over a completed joint. Apply heat evenly using a heat gun, hot-air tool, or appropriate heat source until the tubing uniformly shrinks and conforms tightly to the underlying conductor or connector. Allow the tubing to cool so it sets firmly in place.

Usage recommendations

Use a regulated heat gun at moderate temperature and keep the heat source moving to avoid local overheating. Select tubing with appropriate diameter and wall thickness for the specific conductor size and environmental demands. For outdoor or high-moisture applications, consider additional sealing methods or a product rated for enhanced environmental protection.
