Heat Shrink Tube CellPack CR 25.4/12.7 1 in thin-wall yellow-green 1 m

CellPack CR thin-wall heat shrink tube with original dimensions 25.4/12.7 mm (1 in to 0.5 in) and a 1 m length is designed for insulating, bundling and providing strain relief for cables in compact installations. The yellow-green tube shrinks uniformly when heated, creating a close-fitting protective layer over joints, splices and connectors while maintaining a low profile due to its reduced wall thickness.

Advantages

The thin-wall construction reduces added bulk while maintaining reliable electrical insulation and mechanical protection. Uniform shrink characteristics ensure consistent fit on uneven surfaces and around irregular shapes. The bright yellow-green colour improves visual identification of treated cables and splice points. Supplied as a 1 m length, the tube is convenient for repair, prototyping and short runs.

Suitable for

• Insulating and protecting electrical splices and joints
• Bundling small cable groups and providing strain relief
• Repairing damaged insulation on wires in low‑profile assemblies
• Colour-coding wiring and identifying service points

Key specifications

• Original inner diameter: 25.4 mm reduced to 12.7 mm after shrink
• Wall type: thin-wall for minimal added thickness
• Length: 1 metre
• Colour: yellow-green
• Application: electrical insulation, bundling and strain relief

How to use

Cut the required length from the 1 m tube and slide it over the cable or splice before making the connection. Apply heat evenly using a heat gun, hot air tool or other suitable heat source until the tube contracts and conforms to the substrate. Allow the assembly to cool so the material sets and provides a secure, close-fitting protective layer.

Usage recommendations

Ensure the temperature of the heat source matches the heat shrink material specifications and avoid direct flame. For best results, pre-position the tube so it fully covers the joint and maintain even heating to prevent overheating or uneven shrinkage. Use appropriate personal protective equipment when applying heat and verify electrical insulation with testing where required.
