The Plastica AlfaThreaded Reducing 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 UV-stabilised, high-impact black PP reducing socket is equipped with two different BSP (GAS) female threads and is designed and tested to ensure a working pressure PN16: fitted with central hexagon for easy gripping and metal reinforcement ring in diameters 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.
