Heat-shrink tubing CellPack 204313, 4 m length, single pack

CellPack 204313 heat-shrink tubing is a single-piece insulating tube supplied in a 4 m length for electrical insulation, cable repair and protection. The product is intended for use on electrical wiring, joints and cable harnesses where mechanical protection, strain relief and environmental sealing are required. Supplied as one pack, the tubing is compatible with manual and heat-gun shrinking methods and is suitable for general-purpose wiring tasks, hobby electronics and light automotive repairs.

Advantages

The heat-shrink tubing provides durable electrical insulation and mechanical protection for exposed conductors and splice points. Its single-piece 4 m length reduces the need for multiple short sections and supports continuous runs. A back-winding mechanism and built-in notch help manage the tube when dispensing and prevent the tubing from rolling back into the box, making handling more convenient during installation.

Key specifications

How to use

Cut a suitable length of tubing to cover the exposed conductor, splice or damaged insulation. Slide the tubing over the area to be protected and apply controlled heat with a heat gun, lighter (with caution) or other approved heating tool until the tubing contracts uniformly and forms a snug fit around the cable. Allow the tubing to cool before moving or stressing the cable. For best results, ensure surfaces are clean and free of oils or contaminants prior to shrinking.

Recommendations

Use a temperature-controlled heat gun and apply heat evenly around the tubing to avoid overheating. For automotive or outdoor applications, verify that the chosen tubing material and shrink ratio meet the environmental and temperature requirements of the installation. Store the pack in a dry place away from direct sunlight to preserve flexibility and performance.
