Is the ISO-B quick-connect socket with GW NPT, BSP (1/8" Ã· 1") stainless steel, HANSEN, type HK compatible with ISO 7241-1 B couplers from other manufacturers?

Yes. The ISO-B quick-connect socket with GW NPT, BSP (1/8" Ã· 1") stainless steel, HANSEN, type HK is compliant with ISO 7241-1 B and is specified as interchangeable with ISO-B quick couplings from other manufacturers. Therefore it is compatible with ISO 7241-1 B couplers from other manufacturers, provided the mating coupler also conforms to the same ISO-B standard and appropriate size, pressure rating and seal material are selected for the application.

Can the ISO-B quick-connect socket with GW NPT, BSP (1/8" Ã· 1") stainless steel, HANSEN, type HK be used for steam applications above +149Â°C with EPDM236 seals?

Yes. The ISO-B quick-connect socket with GW NPT, BSP (1/8" Ã· 1") stainless steel, HANSEN, type HK can be used for steam applications above +149Â°C only if fitted with EPDM236 seals, since EPDM236 is specified for use with steam at temperatures above +149Â°C. Ensure correct seal material selection, compatibility with system pressure and media, and that hardware (AISI 303/316) and assembly meet the application's temperature and pressure requirements.

Can the ISO-B quick-connect socket with GW NPT, BSP (1/8" Ã· 1") stainless steel, HANSEN, type HK be used with gases and chemicals?

Yes. The ISO-B quick-connect socket with GW NPT, BSP (1/8" Ã· 1") stainless steel, HANSEN, type HK can be used with gases and many chemicals. The product description explicitly lists gases and chemicals among intended applications (alongside hydraulic oil, water, steam, fuels and oils). Material choices (AISI 303 and AISI 316 stainless steel) provide good general corrosion resistance, and multiple seal materials are available to match media and temperature ranges: - NBR: â40Â°C to +121Â°C (good for many oils and fuels; limited chemical resistance to some solvents). - EPDM: â54Â°C to +149Â°C (excellent for water, steam, many acids and alkalis; poor resistance to hydrocarbons). - EPDM236: for steam above +149Â°C. - Viton (FKM): â29Â°C to +204Â°C (excellent chemical and fuel resistance, suitable for many aggressive media and higher temperatures). Working pressure is up to 344 bar depending on size. Selection guidance: - Choose AISI 316 for better corrosion resistance with aggressive chemicals or corrosive gases. - Match seal material to the specific gas or chemical and operating temperature (consult chemical compatibility charts). - Verify required thread type (NPT or BSP) and size compatibility. - Confirm maximum pressure and flow requirements for your coupling size. For safety and compliance, always review the specific chemicalâs compatibility with the chosen seal and stainless grade, check operating temperature/pressure limits for the selected coupling size, and consult HANSEN or material compatibility data for any aggressive or toxic gases/chemicals before use.
