The ISO-A hydraulic quick coupling socket with shut-off valve and external metric thread is a robust and reliable solution designed for demanding hydraulic systems. Its practical “push-pull” mechanism ensures automatic disconnection in case of accidental hose tension, significantly enhancing safety and ease of use. Manufactured from high-quality galvanized steel, the coupling guarantees durability and resistance to wear, while the NBR sealing provides secure tightness and reliable performance across a wide temperature range from -25°C to +100°C. With a working pressure of up to 250 bar and a safety factor of 4:1, it offers dependable operation even under intensive conditions. The coupling is fully interchangeable with ISO-A quick couplings from other manufacturers, making it a versatile choice for agricultural machinery and other hydraulic applications. Commonly known as “euro couplings,” it ensures efficient oil flow with a pressure drop of only 3 bar, delivering both performance and reliability for professional use.
