The Plastica Alfa Threaded Socket is designed for threaded connections from ø ½” to 4″ in hydraulic applications related to the distribution of pressurised fluids in irrigation and waterworks systems. The socket, made of black, high-impact UV-stabilised PP, has BSP (GAS) female threads and is designed and tested to guarantee a PN16 working pressure: equipped with a central hexagon for easy gripping and a metal reinforcement ring in diameters from 2½ to 4″.
In particular, it is used in drinking water transport systems in aqueducts and civil installations, in irrigation and gardening, geothermal systems, and for conveying wastewater and industrial water.
