Polyolefin Heat Shrink Tube 40mm/20mm 1mb
Flexible and bendable thick-wall heat shrink tube with a 2:1 shrink ratio. After shrinking, the tube remains elastic and can be used on uneven surfaces, adapting its size and shape to the element. It provides excellent mechanical protection and electrical insulation. The installation process is extremely easy and straightforward – simply heat it with hot air. The SALIPT heat shrink tube with a 40mm diameter is a reliable solution for insulating and protecting various elements, not just cables and wires. Thanks to its high-quality material, the tube is durable, elastic, and resistant to mechanical damage, moisture, and changing weather conditions. Ideal for use in electronics, automotive, telecommunications, or industrial and home installations.
