The HANSEN HK quick coupling with internal BSP or NPT thread is a robust and versatile solution engineered in compliance with ISO 7241-1 B and the PED 2014/68/EU directive, ensuring maximum safety and reliability in demanding applications. Manufactured from galvanized steel and available in sizes from 1/2” to 1”, the couplings feature specially hardened steel for enhanced durability and superior resistance to pressure pulsations. For pulsating pressure when disconnected, the working pressure should be reduced by 50%, guaranteeing long-term performance. Fully interchangeable with ISO-B quick couplings from other brands, this product offers seamless integration into existing systems. Designed for a wide range of applications, it is suitable for hydraulic power transmission with hydraulic oil, as well as industrial use with water, steam, fuels, oils, gases, and chemicals. Multiple sealing options are available to match specific operating conditions: NBR seals for temperatures from -40°C to +121°C, EPDM seals for -54°C to +149°C, and Viton seals for -29°C to +204°C. With a working pressure of up to 345 bar depending on size and optimized flow for a 3 bar pressure drop, the HANSEN HK quick coupling delivers efficiency, reliability, and flexibility, making it the ideal choice for industries seeking high-performance connection solutions.
