Silicone Cold Shrink Tubing

Silicone Cold Shrink tubing which provides an insulating tube over cable terminals, splices and connectors.


Silicone Cold Shrink tube is a pre-stretched sleeve of insulating silicone which is intended for protection and insulation of electrical and telecommunications terminals. It is provided on a spiral carrier (called a supporting core) which can be collapsed once the tube is positioned over the desired connection. Common uses for Silicone Cold shrink tubing applications are protection of Coaxial connectors (eg. DIN 7/16 connectors) once field-installed.
The advantage of Silicone cold-shrink tubing is that it can be field installed without any tools, heat, or specialist equipment and once installed it is very robust and long lasting. Exatrum’s Silicone Cold Shrink tubing has been tested to Australia’s tough conditions for trustworthy installation on permanent and industrial applications.
