Is the ISO-B Quick-Connect Socket, Stainless Steel, GW NPT/BSP 1/8"-1", HANSEN HK compatible with other manufacturers’ ISO 7241-1 B (ISO-B) couplings?

Yes. The ISO-B Quick-Connect Socket, Stainless Steel, GW NPT/BSP 1/8"-1", HANSEN HK is designed in compliance with ISO 7241-1 B and guarantees full interchangeability with ISO-B (ISO 7241-1 B) couplings from other manufacturers. Its compliance ensures mechanical and dimensional compatibility, making it suitable for direct mating with other ISO-B quick couplings while providing robust performance across a wide range of media, pressures and temperatures.

Can the ISO-B Quick-Connect Socket, Stainless Steel, GW NPT/BSP 1/8"-1", HANSEN HK be used with steam and high-temperature fluids when equipped with EPDM236 seals?

Yes. The ISO-B Quick-Connect Socket, Stainless Steel, GW NPT/BSP 1/8"-1", HANSEN HK can be used with steam and high-temperature fluids when fitted with EPDM236 seals. The product description explicitly states EPDM236 is intended for steam applications above +149°C, and the HK coupling is engineered for steam and high-temperature media. Constructed from AISI 303/316 stainless steel and rated up to 344 bar (depending on size), the coupling provides corrosion resistance and mechanical strength suitable for demanding, high-temperature service. Ensure the specific operating temperature and pressure of your application fall within the EPDM236 seal limits and the coupling size’s pressure rating before final selection.
