The quick coupling adapter with socket DN 9 and plug DN 6 is a versatile and reliable solution designed for demanding industrial applications. Available with or without a valve, it ensures secure and efficient connections in processes requiring precision and durability. With a 6 mm flow diameter, 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 allows it to handle water in cleaning machines, as well as hot oil and steam, making it a multifunctional choice for various production environments. Engineered to withstand working pressures up to 25 bar and operating temperatures ranging from -20°C to +200°C (with Viton sealing), it guarantees consistent performance even under extreme conditions. The adapter is manufactured from high-quality materials: brass for the socket body, connection, and valve sleeve, and stainless steel for the spring, ring, and balls, ensuring long-lasting resistance to wear and corrosion. This combination of durability, safety, and adaptability makes it an essential component for industries seeking reliable fluid transfer solutions that optimize efficiency and minimize downtime.
