The ISO-B quick coupling socket with valve and internal BSP thread is a reliable solution designed for demanding high-pressure industrial applications involving water, fuels, oils, gases, and chemicals. Manufactured from durable brass and equipped with NBR sealing, it ensures long-lasting performance and resistance to challenging working conditions. When combined with the supplied plug, it forms a secure double shut-off connection that minimizes fluid loss, making it ideal for systems where frequent connection and disconnection are required during servicing or maintenance. Fully interchangeable with ISO-B quick couplings from other manufacturers, it offers flexibility and compatibility across various installations. With an operating temperature range from -20°C to +100°C, a working pressure of up to 180 bar depending on size, and a high safety factor of 4:1, this coupling guarantees both efficiency and safety. The optimized flow rate, measured at a 3 bar pressure drop, further enhances system performance, making it a dependable choice for industries seeking robust, leak-free, and maintenance-friendly solutions.
