Master Flash

Roof pipe flashings designed for square pipes or canals when installation type is problematic or unknown beforehand. Can be used as either a standard or retrofit application.

  • Made of EPDM rubber with soft aluminium, these flashings are compounded specifically for maximum resistance to weathering due to ozone and ultraviolet light
  • 3 sizes to fit 0” to 19-1/4” (0 – 488 mm) diameter pipes (Standard and Retrofit applications differ slightly)
  • Square base
  • Installed by either sliding down the pipe or from wrapping at the side
  • Stainless steel gripper to secure a retrofit cut is included
  • 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 resistant from -55°C to +100°C continuous (+135°C intermittent)
  • Ozone resistance: EPDM 70 hour @ 500 pphm
