Description

ADWHT is designed to protect automotive hydraulic pipes. The crosslinked polyolefin adhesive lined tubing combines excellent mechanical, abrasion and oil resistance.

 

Features

  • Shrink Ratio 1.5 : 1
  • Operating temperature – 35 to 125°C
  • High oil and fuel resistance
  • Good abrasion/dampening properties
  • Colours – Black
  • Minimum shrink temperature 120°C
  • RoHS compliant

 

Applications

  • Covering of hydraulic and pneumatic metal tubes
  • Protects corrosion coating on metallic tubes against chipping and abrasion
  • Vibration dampening where pipes are clipped onto vehicle body
