The ISO-A hydraulic quick coupling socket with shut-off valve and internal BSP thread is a reliable solution designed for demanding power hydraulics applications, particularly in agricultural machinery where efficiency and durability are essential. Commonly known as “euro couplings,” these sockets are fully interchangeable with ISO-A quick couplings from other manufacturers, ensuring maximum compatibility and flexibility in use. Manufactured from high-quality galvanized steel, they provide excellent resistance to wear and corrosion, while the NBR sealing guarantees secure and leak-free connections. Engineered to operate within a wide temperature range from -20°C to +100°C and withstand working pressures up to 350 bar (depending on size), the coupling ensures consistent performance even in challenging conditions. With a safety factor of 4:1 and flow parameters defined at a 3 bar pressure drop, it delivers both reliability and safety in hydraulic systems. This makes it an ideal choice for professionals seeking a durable, efficient, and versatile coupling solution that enhances the performance of modern agricultural and industrial equipment.
