  • Environmentally safe, lead-free aluminium base
  • Installed by sliding down the pipe
  • Perfect for sealing elements like pipes, cables, and canals
  • The soft aluminium base fits easily to most residential roof profiles regardless of pipe location
  • The pull tab design and easy smooth tear grooving is intended to eliminate razor knives and allow for a circular hole
  • Sleeve flexibility accommodates vibration and pipe movement caused by expansion/contraction
  • Cut lines clearly marked to allow for easy installation for multiple pipe sizes

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.
