The 90° socket DN 6 quick coupling with hose tail is a highly versatile solution designed for demanding industrial applications, ensuring reliable performance in environments where precision and durability are essential. Engineered for use with or without a valve, it is widely applied in cooling systems for injection molds and die-cast components made of plastics, aluminum, brass, and zinc alloys. Its robust construction also makes it suitable for water in cleaning equipment, as well as for handling hot oil and steam, offering exceptional flexibility across various processes. With a 6 mm flow diameter, a working pressure of up to 25 bar, and an impressive operating temperature range from -20°C to +200°C (with Viton sealing), this coupling guarantees consistent efficiency even under extreme conditions. Manufactured from high-quality brass for the socket body, connection, and valve sleeve, and reinforced with stainless steel components such as the spring, ring, and balls, it delivers long-lasting resistance to wear, corrosion, and thermal stress. This combination of strength, reliability, and adaptability makes it an indispensable component for industries seeking safe, efficient, and maintenance-friendly fluid transfer solutions.
