The absolute innovation is an outstanding inner diameter, which really deserves the word Highflow. The first 3 colors, Chrome, Deep Black and Shiny Copper, offer great variety to serve a variety of tastes. The completely coordinated product series lets each system appear in its own splendour and there are no limits to individuality in interaction with Alphacool hoses. A chromating process is used to bond the colouring firmly to the brass substrate, thus ensuring the longevity of the intensive colour and preventing the chrome layer from flaking off. A blue Alphacool lettering on some of the connectors emphasizes the special feature of these articles once again. A slightly different connection distributor, a connection terminal, offers many advantages: Hardly any restrictions in the thread length, no flow resistance and it can also be glued anywhere.
