Dual Wall Heat Shrink Tubing, SBRS-(2X)QF

Model: SBRS-(2X)QF

Adhesive-lined heat shrinkable tubing for automotive oil-pipe protection

SBRS-(2X)QF adhesive-lined heat-shrinkable tubing is specially created for protecting automotive oil pipes. This dual wall heat shrink tubing provides preventive protection of automobile brake line, fuel line, hydraulic line and other metal pipes which are vulnerable to bending or clamping during manufacturing, installation, or operation.


Features
  • Shrink ratio: 2:1
  • Semi-rigid outer jacket for protection against mechanical damage
  • Adhesive inner layer for sealing against moisture and corrosion
  • Easy installation
  • High strength bonding, the adhesive layer is hard to be peeled off from pipeline
  • Continuous operating temperature: -45℃~105℃
  • Fully shrink temperature: ≥125℃
