Is the Brass Quick-Connect Plug with Hose End, Series 25 DN 7.4, Two-Way compatible with potable water and food-grade applications?

Brass Quick-Connect Plug with Hose End, Series 25 DN 7.4, Two-Way: Based on the description, this coupling features a solid brass body and valve, an NBR (nitrile) sealing system, and an AISI 301 spring. While brass components and NBR seals are commonly used with water, the description does not state explicit certification for potable water or food-grade use (e.g., NSF/ANSI 61, WRAS, ACS, or food-contact approvals). Therefore, you should not assume it is suitable for potable water or food-grade applications without manufacturer confirmation or relevant certifications. For food or drinking water use, request documentation of material compliance and sanitary/food-contact approvals from the manufacturer.

Can the Brass Quick-Connect Plug with Hose End, Series 25 DN 7.4, Two-Way be used reliably with aggressive chemicals or solvents?

Brass Quick-Connect Plug with Hose End, Series 25 DN 7.4, Two-Way uses a solid brass body and valve, AISI 301 spring and NBR seals. While brass and AISI 301 offer good mechanical durability, suitability with aggressive chemicals or solvents depends primarily on chemical compatibility with brass and NBR. Many aggressive solvents (strong acids, bases, chlorinated solvents, ketones like acetone, and some hydrocarbons) can attack brass or cause swelling/degradation of NBR, compromising seal integrity and causing corrosion or leaks. Therefore, Brass Quick-Connect Plug with Hose End, Series 25 DN 7.4, Two-Way is not generally recommended for reliable use with aggressive chemicals or harsh solvents without verification. For such media you should: - Check chemical compatibility charts for brass and NBR against the specific chemical and concentration. - Consider alternative materials (e.g., stainless steel bodies, FKM/EPDM/PTFE seals) if incompatibility is indicated. - Test the coupling under expected temperature, pressure (up to 35 bar), and exposure duration before full deployment. If you provide the exact chemicals, concentrations and temperatures, I can advise more specifically.

Additional information

Material	B – brass (bronze)

The two-sided shut-off quick coupling plug series 25 DN 7.4 with hose end is designed for demanding applications where reliability, efficiency, and safety are essential. Its solid brass body and valve, combined with a durable AISI 301 steel spring, ensure long-lasting performance even under intensive use. Thanks to the innovative ULTRA-FLO valve, the coupling guarantees exceptional tightness and an impressive flow rate of 780 l/min (Pe=6 bar, Δp=0.5 bar, air), making it an excellent choice for laboratory equipment, precise sampling of liquids and gases, as well as for powering pneumatic tools. The NBR sealing system provides secure operation across a wide temperature range from -20°C to +100°C, depending on the medium, while the maximum working pressure of 35 bar allows for versatile use in both industrial and laboratory environments. This robust and efficient solution combines high performance with ease of use, ensuring smooth processes and reliable connections in every application.
