Is the ISO-B quick connect plug with GW NPT, BSP (1/4" Ã· 1") in AISI 316 stainless steel, HANSEN, type HK compatible with other manufacturers' ISO-B couplings?

Yes. The ISO-B quick connect plug with GW NPT, BSP (1/4" Ã· 1") in AISI 316 stainless steel, HANSEN, type HK is compatible with ISO-B couplings from other manufacturers. It is manufactured to the ISO 7241-1 B standard and described explicitly as interchangeable with ISO-B quick couplings. Compatibility assumes matching ISO-B size, thread type (NPT or BSP as specified), and appropriate seal material for the application (NBR, EPDM, or Viton) and pressure rating (up to 344 bar depending on size). Ensure mating coupling is also made to ISO 7241-1 B and that temperature, fluid compatibility and working pressure are within the selected seal and size limits.

Can ISO-B quick connect plug with GW NPT, BSP (1/4" Ã· 1") in AISI 316 stainless steel, HANSEN, type HK be used for steam and hot oils up to 204Â°C?

Yes - ISO-B quick connect plug with GW NPT, BSP (1/4" Ã· 1") in AISI 316 stainless steel, HANSEN, type HK can be used for steam and hot oils up to 204Â°C only if fitted with Viton seals. The couplingâs AISI 316 construction and PED compliance are suitable for steam and oils; however NBR and EPDM seals have lower maximum temperatures (- no use above 121Â°C and 149Â°C respectively). Ensure the selected sizeâs working pressure (up to 344 bar depending on size) and the specific application pressure/flow conditions are within limits. For steam confirm compatibility with Viton and system pressure/condensation conditions before use.

Can ISO-B quick connect plug with GW NPT, BSP (1/4" Ã· 1") in AISI 316 stainless steel, HANSEN, type HK be used with aggressive chemicals?

Yes. ISO-B quick connect plug with GW NPT, BSP (1/4" Ã· 1") in AISI 316 stainless steel, HANSEN, type HK can be used with many aggressive chemicals, but suitability depends on the specific chemical, temperature and pressure conditions. Why: - Body material AISI 316 stainless steel offers good corrosion resistance to many acids, alkalis and solvents. - Three sealing options allow selection for chemical compatibility: NBR (-40Â°C to +121Â°C), EPDM (-54Â°C to +149Â°C) and Viton/FKM (-29Â°C to +204Â°C). - Designed for hydraulic, water, steam, fuels, oils, gases and chemicals; PED 2014/68/EU compliant and ISO 7241-1 B interchangeable. Important caveats: - NBR is poor with strong hydrocarbons, ketones, and some acids. Use only for compatible oils and mild chemicals. - EPDM resists polar chemicals, hot water and steam but is attacked by hydrocarbons, mineral oils and many solvents. - Viton/FKM has broad resistance to fuels, oils, many solvents and aggressive chemicals, and is the preferred choice for aggressive media at higher temperatures, but still has limits (e.g., incompatible with some amines, ketones, and hot nitric acid). - Working pressure (up to 344 bar) and flow rating must be verified for your chosen size and operating pressure drop conditions. - Consider temperature vs. seal rating: aggressive chemicals at elevated temperature may shorten seal life or cause failure. Recommendation: - Identify the exact chemical(s), concentration, temperature and operating pressure. - Compare against AISI 316 and the chosen seal compound chemical compatibility charts. - If in doubt or for highly corrosive media (e.g., strong oxidizers, concentrated acids), consult Hansen or the supplier for confirmation or consider special materials/coatings and approved seal compounds.
