The ISO-A hydraulic quick coupling socket with shut-off valve and internal BSP thread is a reliable solution designed for demanding hydraulic systems, ensuring safe and efficient operation even under high pressure. Equipped with a pressure eliminator and a practical “push-pull” function, it allows automatic disconnection in case of accidental hose tension, significantly reducing downtime and enhancing operator safety. Manufactured from durable galvanized steel and sealed with high-quality NBR, the coupling guarantees long-lasting resistance to wear, corrosion, and intensive use in agricultural machinery. Commonly known as “euro couplings,” these sockets are fully interchangeable with ISO-A quick couplings from other brands, offering maximum flexibility and compatibility. With an operating temperature range from -25°C to +100°C, a working pressure of up to 250 bar, and a robust safety factor of 4:1, the product ensures reliable performance in power hydraulics using hydraulic oil. The optimized flow rate at Δp = 3 bar further supports efficient energy transfer, making this coupling an essential component for modern agricultural and hydraulic applications.
