The ISO-A hydraulic quick coupling socket with shut-off valve and internal BSP thread is a reliable and durable solution designed for demanding hydraulic systems. In its practical “push-pull” version, it ensures automatic disconnection in case of accidental hose tension, significantly increasing safety and convenience during operation. Widely recognized in the industry as “euro couplings,” it is fully interchangeable with ISO-A quick couplings from other manufacturers, guaranteeing flexibility and compatibility across various applications. Manufactured from high-quality galvanized steel, the socket offers excellent resistance to wear and corrosion, while the NBR sealing ensures secure and leak-free connections. Engineered for use in power hydraulics with hydraulic oil, it is particularly valued in agricultural machinery, where efficiency and reliability are crucial. With an operating temperature range from -25°C to +100°C, a working pressure of 250 bar, and a safety factor of 4:1, this coupling delivers consistent performance even under intensive conditions. The optimized flow rate at Δp = 3 bar further enhances system efficiency, making it a trusted choice for professionals seeking robust, long-lasting hydraulic solutions.
