Is the Quick connector DN2.7 without bulkhead valve, with hose end, brass, series 20KA compatible with potable water and food-grade applications?

Quick connector DN2.7 without bulkhead valve, with hose end, brass, series 20KA . based on the provided description . is suitable for potable water and many food-grade applications only with qualifications. Positives: the coupling is specified for water, constructed from brass, rated to 35 bar and â20Â°C to +100Â°C, and handles non-flammable gases (air, nitrogen), which indicates general fluid compatibility and robustness. Cautions: brass may contain lead or other alloying elements; suitability for potable water or direct food contact depends on the exact brass alloy composition and any surface platings/coatings, plus compliance with relevant standards (e.g., NSF/ANSI 61, WRAS, KTW, or FDA for materials in contact with food). The product description does not state any potable-water or food-contact certifications, nor does it specify dezincification-resistant (DZR) brass or lead-free composition. Recommendation: do not assume compatibility for potable water or food-grade use without manufacturer confirmation and documentation of lead-free/DZR alloy and applicable approvals. Request from the supplier: material certification, migration test results (if for food), and any potable-water/food-contact certifications (NSF/ANSI 61, WRAS, KTW, FDA, or local equivalents). If certifications are absent, choose a coupling explicitly rated and certified for potable water/food applications.

Does the Quick connector DN2.7 without bulkhead valve, with hose end, brass, series 20KA resist corrosion in chlorinated water?

Quick connector DN2.7 without bulkhead valve, with hose end, brass, series 20KA is designed for water, air, nitrogen and other nonâflammable gases and is made of brass. Brass offers moderate corrosion resistance in freshwater, but chlorinated water (especially with higher chlorine concentration, elevated temperature, or long exposure) can cause dezincification and accelerated corrosion of brass. Given the material and the product description, this connector is not specified as chlorineâresistant or specially treated for pool/sea/chlorinated environments. For reliable longâterm use in chlorinated water, a connector made of stainless steel or with a certified antiâchlorine coating should be chosen instead.

Can the Quick connector DN2.7 without bulkhead valve, with hose end, brass, series 20KA be used for compressed oxygen systems?

No. Quick connector DN2.7 without bulkhead valve, with hose end, brass, series 20KA is specified for water, air, nitrogen and other nonâflammable gases and does not list oxygen service. Oxygen systems require components cleaned and certified for oxygen use (oxygenâcompatible materials, oxygen cleaning to remove oils/contaminants, and often specific seals and surface treatments) because oxygen supports combustion and increases fire/explosion risk if contaminants or incompatible materials are present. Although brass and the stated pressure rating (35 bar) could be mechanically suitable, absence of oxygen compatibility and lack of oxygenâcleaning/certification mean this product must not be used in compressed oxygen systems. Use only fittings and quick connectors explicitly rated and certified for oxygen service.
