Flow component especially haemodialysis medical pipeline includes that a conduit (2) has the first and second end tubular connectors (3,4) coaxial that conduit (2) is normally located otherwise with the line that is designed to connect to, an intermediate tubular connector (8) typewriting of female luer each other. One hollow elastic element (9) substantially extends along entire intermediate tubular connector (8), and main body (1) is internally configured, along the chamber (12) of hollow elastic element (9), to be partly diverted to tubular connector (8) towards the middle in use along the flowing of conduit (2) and used by a swirling motion.
