The DN 6 quick coupling plug with external BSPT, NPT, or metric thread is a versatile solution designed for demanding industrial applications. Available with or without a valve, it ensures reliable performance in processes such as cooling injection molds and casting components made of plastics, aluminum, brass, or zinc alloys. Its robust construction allows safe use with water in cleaning systems, as well as with hot oil and steam, making it a flexible choice for diverse production environments. With a 6 mm flow diameter, a working pressure of up to 10 bar, and an impressive operating temperature range from -20°C to +200°C (with Viton sealing), this coupling guarantees efficiency and durability even under extreme conditions. Manufactured from high-quality brass for the plug body and valve, and stainless steel for the spring, it combines strength with corrosion resistance, ensuring long-lasting reliability. This makes it an ideal component for industries seeking precision, safety, and consistent performance in their fluid handling systems.
