The quick coupling socket with Eurostandard MINI DN 5 valve is a compact and highly efficient solution designed for demanding industrial applications. Ideal for use with air, nitrogen, and other non-flammable gases, it ensures excellent flow performance with minimal pressure drop, even in installations where space is limited. Fully interchangeable with RECTUS 21 and EURO DN 5 couplings from other manufacturers, it offers maximum flexibility and compatibility across systems. Its user-friendly design allows convenient one-hand operation, significantly improving workflow efficiency. For enhanced functionality, sockets can be supplied with anodized aluminum sleeves in various colors, enabling easy line identification and improved workplace organization. Built from durable brass and sealed with NBR, the coupling guarantees long-lasting reliability under working pressures up to 35 bar and flow rates reaching 510 l/min at Pe=6 bar, Δp=0.5 bar (air). With an operating temperature range from -20°C to +100°C, it delivers consistent performance even in challenging environments, making it a trusted choice for professionals seeking safety, durability, and efficiency in their pneumatic systems.
