The series of safety fittings, the result of the desire for technical innovation and careful research, has been the "core business" of the company for some years. This is a new and revolutionary method of coupling with multilayer pipes designed, manufactured and patented by aquatechnik to give maximum safety to the joints to be inserted in the walls and outside them. The safety system is characterized by two fundamental factors: • the widening of the tube heads (bell mouth), made with special equipment also patented, which allows you to fit the tube onto the fitting in a simple, fast and totally safe way. • the pipe is positioned and locked to the fitting through the anti-unscrewing cap which eliminates any possibility of harmful movements and, if necessary, can be disassembled allowing the fitting to be recovered very easily.
