Is the Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA compatible with food-grade fluids or potable water?

Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA is designed for water, air, nitrogen and other nonâflamable gases. Materials: brass body, AISI 301 spring and ring, AISI 420 balls, NBR sealing. Operating temperature â20Â°C to +100Â°C. Compatibility with foodâgrade fluids or potable water: not certified for potable water or food contact. Key reasons: - Sealing material is NBR (nitrile), which is not typically approved for direct food contact or longâterm potable water use without specific certification. - Brass may contain lead or other alloys unless specifically certified as dezincificationâresistant or leadâfree for potable applications; no such certification is stated. - No mention of NSF/ANSI, FDA, WRAS or equivalent approvals for drinking water or food contact in the provided description. Conclusion: Based on the provided specification, Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA should not be assumed compatible with foodâgrade fluids or potable water without manufacturer confirmation or appropriate certifications. If you require use with potable water or food, request documentation of material composition and sanitary approvals (e.g., NSF/ANSI 61, WRAS, EC 1935/2004, or FDA compliance) or choose a product explicitly rated for potable/food contact.

Can the Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA be used with lubricants or hydraulic oils?

Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA Format is designed and specified for water, air, nitrogen and other nonâflammable gases. Sealing material is NBR and materials are brass/AISI steels. Use with lubricants or hydraulic oils is not stated in the specification; compatibility depends on oil chemistry and temperature. NBR has limited resistance to some hydraulic fluids (good for mineral oils, poor for some synthetic or phosphate esters) and operating temperature range is â20Â°C to +100Â°C. If your lubricant or hydraulic oil is mineralâoil based and within the temperature range, it may be acceptable, but for synthetic fluids, aggressive additives or high temperatures, do not use without manufacturer confirmation. Recommend contacting the manufacturer with the exact oil specification for final approval.

Can the Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA be used with oxygen or other oxidizing gases?

No. The Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA is specified for water, air, nitrogen and other non-flammable gases. It uses brass, AISI 301/420 steel components and NBR seals, and its materials and sealing are not rated for oxygen or other oxidizing gases. Oxygen service requires components and seals certified for oxygen use (oil- and grease-free assembly, oxygen-compatible materials and seals such as PTFE or specific oxygen-rated elastomers) because standard brass, steel springs/balls and NBR seals can present fire, combustion or degradation risks in oxygen-enriched atmospheres. Therefore do not use this Quick-connection socket DN2.7 with valve, with hose end, brass, series 20KA with oxygen or other oxidizing gases.
