The Curaflex Nova Uno M/T has been designed to seal pipes and cables that have been already installed, the hinged design makes it easy to install and the replaceable insert means that you can even add services at a later date.
The Curaflex Nova Multi with its modular sealing inserts means that you can instal the gasket with the blind plug to seal the penetration completely, then when the service is to be installed the modules can be removed to seal the pipe/cable.
