The leak-free flat-face quick coupling is engineered for demanding hydraulic applications, particularly in construction machinery where sudden pressure surges are common. Its robust design incorporates a safety pin that prevents accidental disconnection, ensuring maximum reliability and operator safety even in the toughest conditions. The coupling allows convenient one-handed operation, significantly improving workflow efficiency and reducing downtime. Manufactured from high-grade steel with a durable zinc-nickel coating—except for the 3/16″ size, which is made of galvanized steel—it offers outstanding resistance to corrosion and wear, extending service life in harsh environments. Fully interchangeable with ISO-F quick couplings from other brands and compliant with ISO 16028 standards (excluding size 3/16″), it provides seamless integration into existing hydraulic systems. Depending on the application, users can select between NBR seals, suitable for temperatures from -25°C to +100°C, or viton seals, designed for extreme conditions ranging from -15°C to +200°C. With a working pressure capacity of up to 720 bar, this quick coupling guarantees secure, efficient, and leak-free hydraulic power transmission, making it an ideal solution for both industrial and mobile machinery applications.
