The DN 6 quick coupling socket with hose tail is a highly versatile solution designed for demanding industrial applications, ensuring reliable and efficient connections in a wide range of processes. With a 6 mm flow diameter, it guarantees optimal fluid transfer under working pressures up to 25 bar and withstands extreme operating temperatures from -20°C to +200°C, thanks to the use of high-quality Viton sealing. Manufactured from robust brass for the socket body, connection, and valve sleeve, and reinforced with stainless steel components such as the spring, ring, and balls, it offers exceptional durability and resistance to wear. This coupling is widely applied in cooling systems for injection molds and casting parts made of plastics, aluminum, brass, and zinc alloys, as well as in water circuits of cleaning machines, hot oil installations, and steam applications. Its precise engineering ensures leak-free performance, quick assembly, and long service life, making it an indispensable component for industries seeking efficiency, safety, and reliability in fluid handling systems.
