Wakaflex® Uni Outlet is a lead-free, flexible, adhesive sealing collar where flue pipes and soil stacks penetrate the roof.
The Wakaflex® Uni Outlet is the ideal solution for sealing penetrations in the roof. The outlet is extremely flexible as it is designed to fit a wide range of outlet diameters. It is also very easy to install and unlike other methods of sealing such as aluminium or lead, if the seal needs to be extended, extra Wakaflex® can simply be added to accomodate it.
