The ISO-A hydraulic quick coupling with shut-off valve and internal metric thread is a reliable and versatile solution designed for demanding power hydraulics applications, particularly in agricultural machinery where efficiency and durability are crucial. Commonly known as “euro couplings,” this component ensures full interchangeability with ISO-A quick couplings from other manufacturers, offering flexibility and ease of integration into existing systems. Manufactured from high-quality galvanized steel, it provides excellent resistance to wear and corrosion, while the NBR seal guarantees secure and leak-free operation even under intensive use. With an operating temperature range from -25°C to +100°C and a working pressure of up to 250 bar, supported by a 4:1 safety factor, the coupling delivers consistent performance in diverse conditions. Its optimized design ensures a stable flow rate at Δp = 3 bar, supporting smooth hydraulic operations and minimizing downtime. Engineered for reliability, this quick coupling is the ideal choice for professionals seeking long-lasting performance, safety, and compatibility in modern hydraulic systems.
