  • Made of high-temp silicone with soft aluminium base, these flashings are compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light

  • Square base
  • Available in red colour
  • Installed by either sliding down the pipe or from wrapping at the side
  • Stainless steel gripper available upon request
  • Perfect for sealing square pipes and vents
  • The soft aluminium base fits easily to most metal roof profiles regardless of pipe location
  • Sleeve flexibility accommodates vibration and pipe movement caused by expansion/contraction
  • Easy installation with farmer screws
  • Cut lines clearly marked to allow for easy installation for multiple pipe sizes
  • Temperature resistance: -74°C to 225°C continuous (+260°C intermittent)
