Master Flash

Roof pipe flashings ideal for when the installation type is problematic or unknown beforehand. Can be used as either a standard or retrofit application.

  • 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
  • 9 sizes to fit 5/8” to 28 1/2” (15-724mm) diameter pipes
  • Available in 2 colours – grey and red
  • Square base
  • Installed by either sliding down the pipe or from wrapping at the side
  • Designed with a clear groove to ensure a smooth cut
  • Stainless steel gripper to secure a retrofit cut is included
  • Perfect for sealing elements like pipes, cables, and canals
  • 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)
  • Ozone resistance: 70 hour @ 500 pphm

Although colour stabilizers are milled into the primary raw material, a slight fading is to be expected over time. The properties and guarantees of the product will not be affected.
