Is the Double-Sided Quick-Connect Plug, Brass, BSP Female, Series 25 DN 7.4 compatible with both gases and liquids at 35 bar and -20°C to +100°C?

Yes. The Double-Sided Quick-Connect Plug, Brass, BSP Female, Series 25 DN 7.4 is rated for a working pressure up to 35 bar and a temperature range of −20°C to +100°C (specified “depending on the medium”). Its brass construction, NBR seals and AISI 301 spring make it suitable for both gases and liquids in demanding applications (laboratory equipment, liquid and gas sampling, pneumatic tools). Ensure compatibility with your specific fluid or gas (chemistry, vapour pressure, additives) and verify NBR seal compatibility at the extremes of the temperature range; for aggressive media or temperatures near limits, consult the manufacturer for confirmation or alternative seals.

Can the Double-Sided Quick-Connect Plug, Brass, BSP Female, Series 25 DN 7.4 be used for continuous sampling of corrosive gases or liquids given its brass and NBR construction?

No. The Double-Sided Quick-Connect Plug, Brass, BSP Female, Series 25 DN 7.4 is constructed from brass with NBR (nitrile) sealing elements. Both materials have limited chemical resistance: brass (a copper–zinc alloy) can corrode or suffer dezincification when exposed to many corrosive gases and liquids (acidic, chloride-containing, ammonia, hydrogen sulfide, etc.), and NBR is vulnerable to strong oxidizers, aromatics, ketones, some chlorinated solvents and certain acids/alkalis. The product description highlights durability and suitability for laboratory sampling and many gases/ liquids, but it does not claim compatibility with corrosive media or continuous exposure to aggressive chemicals. If you need continuous sampling of corrosive substances, choose couplings made from corrosion-resistant materials (e.g., stainless steels like 316/316L, Hastelloy, Monel, or non-metallic materials compatible with the specific chemical) and elastomers rated for the medium (e.g., FKM/Viton, EPDM, PTFE). Always consult chemical compatibility charts and the manufacturer’s guidance for the specific media, concentration, temperature and exposure duration before using the Double-Sided Quick-Connect Plug, Brass, BSP Female, Series 25 DN 7.4 for corrosive sampling.
