Flexible Base Design

Sealing tightly with sealant and almost any type of fastener, the flexible base is virtually compatible with any roofing material -- metal, plastic, asphalt, tile, rubber membrane, and more.

Resilient Design

Silicone pipe flashing is unaffected by:

  • Ice/snow
  • Hail stones
  • Vibration
  • Expansion/Contraction

Environment Control

Provides a permanent seal that controls gaseous or liquid environments to eliminate leakage and odor contamination.

Roof Pitch-Adaptability

The stepped-cone design adapts to most roof pitches. Increase one size larger for higher pitch roofs.


  • Hot Pipes, stove pipes, chemical pipes
  • Plumbing, heating/air conditioning vents and equipment
  • Electrical service entrances
  • Solar collection pipes
  • Grain augers
  • TV aerials
  • Masts, vents or pipes through decks or bulkheads
  • Lighting conductors
  • Pest control


Manufacture provides 20 year limited warranty.

SLIDE... Slide down over pipe. (A non-petroleum base lubricant will ease installation.). Use RETRO-FIT boot where pipe is not accessible.

SEAL... Apply a bead of sealant between base and roof.

FASTEN... Use exterior grade fasteners with sealing washers to complete sealing. For UPC installation, fastener spacing may not exceed 1-1/2 inch (38mm).
