Cellpack krimpkous 4,8-2,4 mm transparant 10 m dispenserbox 127051

Electricians and maintenance technicians reach for this Cellpack heat shrink tubing when they need reliable insulation and strain relief on cable splices, terminations, and repairs. The transparent polyolefin sleeve shrinks to half its original diameter under heat, conforming tightly to the underlying wires for a secure, professional finish.

Why choose it

The 2:1 shrink ratio means one size covers a range of cable diameters, reducing the number of SKUs you need to stock. The transparent finish allows visual inspection of the connection after shrinking, and the dispenser box keeps the tubing clean and tangle-free on the workbench or in the van.

Ideal use cases

• Insulating soldered or crimped connections
• Bundling wires in control panels
• Providing mechanical protection and strain relief
• Colour coding when used over coloured wires

Good to know

The tubing is halogen-free and self-extinguishing, making it suitable for use in enclosed spaces where fire safety is a concern. Shrink with a heat gun or gas torch, keeping the heat source moving to avoid scorching.
