Heat-shrink tubing CellPack 127418, black, 100 cm

CellPack 127418 is a black heat-shrink tubing 100 cm long designed for electrical insulation, cable protection and strain relief. The sleeve is made of thermally activated polyolefin that contracts when heated to form a tight, protective layer over wire splices, connectors and joints. This tubing provides enhanced insulation and mechanical protection for repair, maintenance and industrial wiring tasks where a reliable shrink fit is required.

Advantages

The heat-shrink sleeve delivers consistent diameter reduction for secure sealing and improved strain relief. Its polyolefin composition offers good electrical insulating properties and resistance to abrasion. The black color provides low visibility for installations and improved UV resistance in exposed applications. The 100 cm length gives flexibility for multiple short repairs or longer runs on single cables.

How to use

Cut the tubing to the required length and slide it over the cable or connection so it fully covers the splice or joint. Apply heat evenly using a heat gun, hot-air tool or flame at a controlled distance until the tubing uniformly shrinks and forms a tight seal around the conductor and connector. Allow the sleeve to cool so it sets in place before handling the assembly further. Ensure the heat source and procedure match the thermal tolerance of nearby components.

Recommendations

Before shrinking, check that surfaces are clean and free from oils or debris to ensure good adhesion and sealing. Use a regulated heat gun for even shrinkage and avoid direct open flame near sensitive components. For runs exposed outdoors, verify compatibility with UV exposure and environmental conditions; for critical seals, consider additional adhesive-lined tubing or supplementary sealing methods.
