The HFT quick coupling socket with internal BSP thread is a high-performance solution designed for demanding hydraulic systems exposed to extreme pressure fluctuations. Its flat-face, leak-free connection ensures maximum reliability, while the additional O-ring on the socket body effectively prevents accidental loosening caused by vibrations, guaranteeing safe and stable operation even in harsh environments. Engineered to allow tightening under residual pressure up to 350 bar, the coupling provides exceptional flexibility and efficiency during maintenance or system adjustments. Manufactured from robust carbon steel with a premium zinc-nickel coating, it delivers corrosion resistance several times higher than standard zinc plating, extending service life and reducing downtime. Fully compliant with API 16D standards for BOP applications, the HFT series is ideally suited for critical operations where safety and durability are paramount. With NBR sealing, it offers dependable performance across a wide temperature range from -40°C to +106°C, while operating pressures up to 550 bar (depending on size) make it a versatile choice for high-pressure hydraulic circuits. Optimized flow characteristics, defined at a 3 bar pressure drop, ensure efficient energy transfer and system performance, making the HFT quick coupling socket a reliable and cost-effective component for modern hydraulic applications.
