Heat Shrink Tubing

Shrinkflex Heat Shrink Tubing range is available in many grade and colors. It is a flexible, pre-stretched tubing, engineered from a wide range of polymers, that will shrink to a fixed diameter when sufficient heat is applied. Its diameter and thickness can vary, and it is rated by its expansion ratio.


Shrinkflex 3:1 Polyolefin Heat Shrink Tubing
is available in 11 Colours.

The high shrink ratio of Shrinkflex 3:1 Polyolefin Heat Shrink Tubing ensures that the tubing will slip over large connectors or plugs and still provide a tight, professional seal when shrunk.
