The HANSEN type HK quick coupling socket with internal thread is a versatile and reliable solution designed in accordance with ISO 7241-1 B standards, ensuring compatibility and interchangeability with ISO-B quick couplings from other leading manufacturers. Engineered for demanding applications, it is suitable for hydraulic power transmission with hydraulic oil as well as a wide range of industrial uses, including water, steam, fuels, oils, gases, and various chemicals. Manufactured from high-quality brass, the socket guarantees durability and resistance to wear, while the sealing options in NBR or EPDM provide secure performance across diverse media. Depending on the sealing type, the coupling operates efficiently within a broad temperature range from -54°C to +149°C, making it ideal for both extreme cold and high-heat environments. With working pressures of up to 207 bar, depending on the size, and a flow capacity optimized for a pressure drop of just 3 bar, the HK socket ensures consistent performance and energy efficiency. For added reliability, sockets up to 1″ feature a second O-ring instead of a retaining ring, enhancing sealing security. Available with BSP or NPT threads, this quick coupling socket offers maximum flexibility, making it a trusted choice for industries seeking robust, leak-free, and high-performance connections.
