The HANSEN type HK quick coupling socket with internal thread is a reliable and versatile solution designed in accordance with ISO 7241-1 B, ensuring full compatibility with ISO-B quick couplings from other manufacturers. Manufactured from high-quality galvanized carbon steel, it guarantees durability and resistance even in demanding working conditions. Sizes from 1/2” to 1” are produced from specially hardened steel, significantly increasing resistance to pressure pulsations and extending service life. For applications involving pulsating pressure on a disconnected coupling, the maximum working pressure should be reduced by 50% to maintain optimal safety and performance. With a working pressure of up to 345 bar, depending on the size, and flow rates measured at a 3 bar pressure drop, this coupling offers efficiency and reliability across a wide range of uses. Suitable for hydraulic power transmission with hydraulic oil, as well as industrial applications involving water, steam, fuels, oils, gases, and chemicals, it provides exceptional versatility. Available with BSP or NPT threads and sealing options in NBR or Viton, it ensures secure connections and adaptability to various media. The wide operating temperature range from -40°C to +204°C, depending on the sealing type, makes it an excellent choice for both extreme cold and high-temperature environments. Designed for professionals who value safety, efficiency, and compatibility, the HANSEN HK quick coupling socket delivers dependable performance in every application.
