Heat-shrink tubing CellPack 203679, 7 m length, single pack

CellPack 203679 is a single 7 m length heat-shrink tubing intended for electrical insulation and mechanical protection of cables and wire joints. The tubing shrinks when heated to form a tight, protective covering over splices, repair points and exposed conductor areas. Supplied as one continuous tube suitable for cutting to length, it is designed for general wiring tasks, cable bundling and protecting connections in domestic and light industrial environments. A standard spool may include sections tied together.

Advantages

This heat-shrink tubing provides reliable insulation and strain relief for repaired or joined conductors, improving mechanical protection and reducing exposure to moisture and contaminants. Its continuous 7 m length allows flexible cutting for multiple repairs or organized bundling, and the shrink-fit ensures a secure seal around irregular shapes and connectors. The product is compatible with common heat sources used for shrink tubing application.

Suitable for

• Insulating and sealing wire splices and solder joints
• Repairing damaged cable insulation
• Bundling and identifying cable runs
• Providing mechanical protection and strain relief on connectors

Key specifications

• Length: 7 metres of continuous heat-shrink tubing
• Form: single continuous tube supplied as one pack
• Function: electrical insulation and mechanical protection
• Application environment: suitable for domestic and light industrial use
• Usage: cut-to-length, shrinkable with heat to form a tight seal

How to use

Measure and cut a section of tubing slightly longer than the area you need to cover. Slide the tubing over the cable or splice before making the permanent connection when possible; for repairs, position the tubing over the exposed area. Apply heat evenly using a heat gun, hot air tool or other suitable heat source until the tubing shrinks tightly around the component. Allow the tubing to cool and check for a secure fit. Replace tubing if signs of overheating or damage appear.

Usage recommendations

For best results, use a regulated heat gun and apply heat progressively to avoid uneven shrinkage or surface scorching. Select a section that provides adequate overlap on both sides of the repair, and avoid exposing the tubing to flames or direct open flame. Store in a cool, dry place away from prolonged UV exposure.
