Demonstration of Dual Wall Heat Shrink Tubing Installation
QSZH Heat Shrink Tubing: High shrink ratio, adhesive lined semirigid polyolefin tubing
Zero halogen, dual wall heat shrink tubing designed to provide environmental sealing, mechanical and electrical protection of in-line splices in an automotive environment.
Overview
The tubing is centered over the splice area and on heating the adhesive melts and is squeezed around where the wires are crimped or welded and between wire cores by the shrinking action of the sleeve.
The installed QSZH-125 tube provides low profile mechanical protection against flexing, abrasion and cut-through as well as electrical insulation.
There are five QSZH-125 sizes to cover a wide range of typical automotive splice configurations having a maximum of seven wires on either side. The sleeves are marked 1, 2, 3, 3A and 4 to denote the size.
Features
- 4:1 shrink ratio.
- Operating temperature from –40°C up to +125°C (3000 hrs).
- Minimum full recovery temperature: +135°C.
