CellPack 203790 θερμοσυστελλόμενο μακαρόνι χωρίς κόλλα, καφέ, 12 mm, 3:1, 8 m

Electricians and maintenance technicians use this brown heat shrink tubing to insulate and bundle cables in control cabinets and industrial installations. The 12 mm supplied diameter shrinks to 4 mm at a 3:1 ratio, creating a tight, durable seal around irregular shapes. Made from cross-linked polyolefin without adhesive, it provides reliable electrical insulation and strain relief for wire harnesses and connectors.

Why choose it

The 3:1 shrink ratio allows the tubing to conform to components with varying diameters, reducing the need for multiple sizes. Its self-extinguishing polyolefin material meets the demands of industrial environments, and the brown colour is suitable for colour-coding or matching existing insulation.

Ideal use cases

• Insulating electrical splices and terminations
• Bundling wires in automotive and marine applications
• Providing strain relief for cable entries
• Colour coding for phase identification

Good to know

The tubing is supplied as a continuous 8 m length, allowing you to cut it to the required size. It is not adhesive lined, so it slides easily over cables before shrinking with a heat gun.
