Insignia Hydrophilic Connection Hat

Key Features:

The Insignia™ Hydrophilic Connection Hat is utilized to provide a positive compression seal at the main-to-lateral junction of a sewer collection system. This hat is a 360 degree sealing gasket that prevents water tracking behind the liner at the main-to-lateral junction of a collection system where the maximum amount of infiltration and inflow (I&I) occurs. The Insignia Hydrophilic Connection Hat creates a seal at the main source of infiltration ensuring that this sealing technology, along with a structural CIPP repair, is the most effective solution for rehabilitating the main-to-lateral connection. The Insignia product line used in conjunction with CIPP lining is more than just a structural repair; it’s a water-tight sealed system!
