The non-drip flat-face ISO-F quick coupling socket with shut-off valve and internal BSP thread is a highly reliable solution for hydraulic power transmission, specifically engineered for demanding applications in construction machinery. Its robust galvanized steel body ensures exceptional durability and resistance to wear, while advanced sealing options in NBR or Viton guarantee secure performance across a wide temperature range from -25°C up to +200°C. Designed for maximum operator convenience, the coupling allows effortless one-hand operation and is equipped with a safety pin that effectively prevents accidental disconnection, enhancing both safety and efficiency on site. With a working pressure capacity of up to 300 bar, depending on the coupling size, and a safety factor of 4:1, it delivers consistent performance even under extreme conditions. The flat-face design minimizes fluid loss and contamination during connection and disconnection, ensuring a cleaner, more sustainable hydraulic system. Fully interchangeable with ISO-F quick couplings from other manufacturers, it offers flexibility and compatibility across various equipment. Optimized flow rates at Δp = 3 bar further support smooth and efficient hydraulic operations, making this quick coupling socket a dependable choice for professionals seeking reliability, safety, and ease of use in heavy-duty environments.
