Heat-shrink tubing CellPack 240167, 1 m length, single-piece pack

CellPack 240167 heat-shrink tubing is a single-piece, 1 m length sleeve intended for insulating and protecting electrical cables and wire joints. Made to shrink reliably when exposed to heat, this tubing provides a close-fitting protective layer that increases mechanical durability and restores electrical insulation on repaired or joined conductors. The product is supplied as one continuous 100 cm length and is suitable for use in a variety of electrical installation, maintenance and repair tasks.

Advantages

Heat-shrink tubing offers consistent shrinkage around irregular shapes, improving strain relief and protecting connections from abrasion and environmental factors. The single-piece 1 m length allows flexible cutting to required sizes with minimal waste. The product is compatible with common heat sources used in electrical work and provides a quick method to insulate and secure splices and terminals.

Suitable for

• Insulating repaired or spliced wires in household and industrial electrical systems
• Protecting cable joints and terminals from abrasion and moisture
• Colour-coding and bundling of small cable runs
• Securing and reinforcing flexible cables and wire ends

Key specifications

• Length: 1 m continuous single-piece sleeve
• Material: heat-shrinkable polymer (provides electrical insulation and mechanical protection)
• Shrink method: heat-activated radial shrinkage to form close fit around conductors
• Typical application: insulation of wire joints, strain relief and protection of terminals
• Compatibility: suitable for use with standard heat sources used in electrical work (heat gun, lighter with care)

How to use

Cut the heat-shrink tubing to the required length, slide it over the cable or joint to be insulated, then apply heat evenly along the tubing until it contracts and forms a snug seal around the conductor or connector. Ensure the area is clean and dry before application and avoid overheating by maintaining an appropriate distance and even motion of the heat source. Allow the tubing to cool undisturbed so the material stabilises around the cable.

Recommendations

Measure the diameter of the cable or splice and select a tubing length that provides sufficient overlap at both ends; when using an open flame, proceed with caution to prevent damage to insulation or surrounding materials. If multiple sections are required, cut and fit each piece individually; other lengths are available on request from the manufacturer.
