Brass DN5 Quick-Connect Socket with Valve and Hose End, Series 21KA

The quick coupling socket with valve, Eurostandard DN5 (MINI), series 21KA, is a compact and highly efficient solution designed for demanding industrial applications where minimal dimensions must be combined with maximum performance. Available in two practical versions—one with a corrugated hose end and the other with a nut end for thermoplastic hoses—it ensures flexibility of use across a wide range of systems. Engineered for convenience, the socket allows simple one-handed operation, significantly improving workflow efficiency. Despite its small size, it delivers impressive flow rates of 560 l/min for air at 6 bar with minimal pressure drop, and 8 l/min for water at Δp=1 bar, ensuring reliable performance in both pneumatic and hydraulic environments. With a working pressure of up to 35 bar, it guarantees durability and safety even under intensive use. Manufactured from high-quality brass with stainless steel springs and balls, it offers excellent resistance to wear and corrosion, while NBR sealing ensures reliable tightness and long service life. Designed to operate in a wide temperature range from -20°C to +100°C, this coupling socket is a versatile and robust choice for industries seeking efficiency, reliability, and ease of use in compact form.
