The HANSEN HK quick coupling socket with internal BSP and NPT thread is a high-performance solution designed in compliance with ISO 7241-1 B, ensuring full interchangeability with ISO-B couplings from other leading manufacturers. Produced in line with the stringent requirements of the Pressure Equipment Directive PED 2014/68/EU, it guarantees reliability and safety across a wide range of applications, including hydraulic power transmission with oil, as well as industrial uses involving water, steam, fuels, oils, gases, and chemicals. Its integrated self-sealing poppet valve provides superior leak-tightness under both high and low pressure, while in cases of pulsating pressure at the disconnected coupling, the maximum working pressure should be reduced by 50% to maintain optimal performance. Manufactured from durable AISI 303 stainless steel, the coupling is available with sealing options in NBR, EPDM, or Viton, covering operating temperatures from -54°C up to +204°C. With a working pressure capacity of up to 152 bar, depending on size, and flow parameters calculated for a 3 bar pressure drop, this coupling offers outstanding efficiency, durability, and versatility, making it an ideal choice for demanding industrial and hydraulic systems.
