Dual Wall Heat Shrink Tubing

No image set

NTE's Dual Wall Heat Shrink Tubing is flexible, polyolefin based heat shrinkable tubing with a thermoplastic adhesive inner liner which flows when heated. After shrinkage and upon cooling, it provides a permanent flexible water proof barrier. This tubing is suitable for a wide range of applications, such as encapsulation cables, wires, electrical components and splices. The choice of high shrink ratios means more flexibility of usage such as in the covering of irregular shaped objects.


  • 3:1 shrink ratio
  • MIL DTL 23053/4, Class 3

  • Available in Black, Blue, Red, Green, Yellow, White and Clear
