This joint has been designed to repair water leaks placed on the inner (or female) joint on pressure pipelines. Otherwise from HYDRO STOP joint, this is characterized by a lighter and simpler structure, because it is designed to work only in case of wrong gasket positioning inside female joint. HYDRO TECH cannot be used to repair leaks from a fault of the external walls of the pipe. Thanks to its tightening system, it restores the proper functioning of the gasket without dismantling the pipes. Made of electro-welded S235JR (or higher) carbon steel it is ultra-light and easy to mount, due to its very simple structure. This joint can be made on request also for out-of-standard sizes. It can be uses for at least DN 300 pipelines.
