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,” this model ensures full interchangeability with ISO-A quick couplings from other manufacturers, providing flexibility and compatibility across various systems. Manufactured from robust galvanized steel, it offers excellent resistance to wear and corrosion, while the NBR sealing guarantees secure and leak-free connections. The integrated pressure eliminator enhances safety and ease of use, even under challenging operating conditions. With a wide temperature range from -25°C to +100°C and a working pressure of up to 320 bar, supported by a 4:1 safety factor, the coupling delivers reliable performance in intensive hydraulic operations. Optimized for high flow rates at Δp = 3 bar, it ensures smooth oil transfer, minimizing downtime and maximizing productivity in the field. This makes it an ideal choice for professionals seeking a durable, efficient, and universally compatible hydraulic connection solution.
