The flat-face quick-connect coupling plug with static pressure eliminator is engineered for demanding hydraulic applications, particularly in construction machinery where sudden pressure surges are common. Designed for one-handed operation, it ensures fast, safe, and leak-free connections, significantly reducing downtime and increasing efficiency on site. Manufactured from high-strength steel with a durable zinc-nickel coating, it offers excellent resistance to corrosion and wear, guaranteeing long service life even in harsh working environments. The coupling is fully interchangeable with ISO-F quick couplings from other manufacturers and complies with ISO 16028 standards, ensuring compatibility and reliability across various systems. With a working pressure of up to 400 bar and NBR sealing suitable for temperatures from -25°C to +100°C, it provides robust performance in both industrial and mobile hydraulic applications. The integrated pressure eliminator allows coupling under residual pressure—up to 250 bar on the plug side—while maintaining zero bar on the socket side, enabling smooth and effortless connection. Optimized flow characteristics at Δp = 3 bar ensure efficient hydraulic power transfer, making this coupling an ideal solution for operators seeking maximum productivity, safety, and versatility in their hydraulic systems.
