The Alfarapid coupling is ideal for connecting grooved pipes (Victaulic type) via couplings and is used in the water treatment, ultrafiltration, irrigation, plumbing and thermo-hydraulics sectors. It stands out for ease and speed of assembly, saving time and money during installation and maintenance, as welding, flanging, threading and gluing are not required.
The coupling, made of PP, is characterised by high quality and durability, resistance to pressure and mechanical stress and is, like the entire Alfarapid system, a viable alternative to metal systems.
