Optimal contact pressure through an automatically set correct torque. Specially developed ITL nuts reliably detach at the defined torque.


The specially developed ageing-resistant elastomer prevents friction-reducing substances from causing the gasket insert to slip under load.


When sealing the soles and basement walls of supply and disposal lines, Curaflex® sealing gaskets are the first choice for radon-contaminated floors.

Curaflex Nova® with Integrated Torque Limiter (ITL)


Implementation of supply and disposal lines through existing walls (masonry) with wall thicknesses from 300 mm to 1650 mm and line diameters from 50 mm to 400 mm.

The masonry was provided with a PMBC surface seal. The lines partly in stock and partly in a close arrangement. In addition, the line was close to the base of the building. The project planner's requirement was to create a clean separation between the building and pipe seals.
