  • Do you need a weatherproof solution for your cables?
  • Do you need a solution to accommodate large bulky cables or adapters?

Then the 6.1 High Ratio Heat Shrinking Tubing is the ideal solution for you!

This heat shrink tubing is made from a specially formulated cross-linked polyolefin with a highly flexible adhesive liner to create a puncture resistant seal.

Tough and flexible, the flame retardant tubing can be used for harnessing large cable bundles.

The Polyolefin tubing can shrink down to a 1/6th of its size and provides a permanent, waterproof and environmental seal that provides superior resistance.

The Tubing is easy to install and the high shrink ratio covers even irregular shapes, once you know the tricks for proper shrinking.

Excellent chemical, physical and electrical properties that meet to UV94V-O standards of flammability, is Military specified under MIL-DTL-23053/15, Class 1, and offers excellent UV resistance.

Comes in 5 sizes available to meet all heat shrinking needs.

*If you choose First Class Mail as a shipping option, the product will be folded to fit into an envelope.
