Heat Shrink Tubing without Glue diameter 6,4mm 2:1 Red

The heat shrink tube without adhesive is designed for insulation, protection and finishing of electrical cables, wiring harnesses, connections and electronic components.
Thanks to its 6.4 mm internal diameter and 2:1 shrink ratio, the tube easily adapts to cables and components of different shapes, ensuring uniform coverage after heating.
The polyolefin material provides high flexibility, good mechanical resistance and excellent electrical insulation properties, making the product suitable for both professional applications and maintenance, repair and protection work.
The tube is particularly suitable for cable identification, cable assembly and mechanical protection against abrasion, bending, dust and accidental contact.
The low minimum shrink temperature allows practical and controlled application, reducing the risk of damaging components during heating.
Being without internal adhesive, it is ideal for applications where a clean, flexible and easy-to-handle finish is required, without adhesive sealing.
The red version is particularly suitable for visual identification of wiring, distinguishing electrical lines, polarity marking or cable classification inside electrical panels, systems, automotive wiring and industrial applications.
The self-extinguishing properties, RoHS compliance and resistance to low and high temperatures make this tube suitable even for demanding operating environments.
