The DN 13 quick coupling socket with hose end, available with or without valve, is a highly versatile solution designed for demanding industrial applications. With a flow diameter of 13 mm, it ensures efficient media transfer under a working pressure of up to 25 bar and can reliably operate in a wide temperature range from -20°C to +200°C when equipped with viton seals. 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 guarantees durability and long service life even in intensive use. This coupling is widely applied in cooling systems for injection molds and die-cast parts made of plastics, aluminum, brass, and zinc alloys, as well as in processes involving water in cleaning machines, hot oil, or steam. Its precise engineering and high-quality materials make it an excellent choice for industries seeking safe, efficient, and reliable connections that optimize productivity and minimize downtime.
