Dual Wall Heat Shrink Tubing, SBRS-(4X)G

Model: SBRS-(4X)G

Adhesive-lined heat shrinkable polyolefin tubing

SBRS-(4X)G dual wall heat shrink tubing is adhesive-lined shrinkable polyolefin tubing with ability to provide corrosion protection and environmental sealing electrical insulation of wire splices, wire harness bundles, breakouts and connector-to-cable transitions in automotive and marine electrical applications.


Features
  • 4:1 shrink ratio
  • Low longitudinal shrinkage
  • Superior sealing against water, moisture or other contaminants
  • Ideal for sealing and covering of connectors with large diameter differences
  • Inner adhesive bonds to plastics, steel and polyethylene
  • Flame retardant (outer jacket only)
  • Continuous operating temperature: -45℃~125℃
  • Fully shrink temperature: ≥125℃
