Is the Quick-connection socket DN2.7 with valve, threaded, brass, series 20KA compatible with compressed nitrogen at 35 bar?

Yes. Quick-connection socket DN2.7 with valve, threaded, brass, series 20KA is compatible with compressed nitrogen at 35 bar. The product specification lists nitrogen among the suitable media and gives a working pressure of 35 bar. Materials (brass body, AISI 301 spring/ring, AISI 420 balls) and NBR seals are suitable for dry, non-corrosive nitrogen within the stated operating temperature range (-20Â°C to +100Â°C). Ensure nitrogen is dry and free of contaminants and confirm seal compatibility if oxygen or other reactive additives are present; for special purity or temperature extremes, consult the manufacturer.

Can the Quick-connection socket DN2.7 with valve, threaded, brass, series 20KA be used for potable water applications?

Quick-connection socket DN2.7 with valve, threaded, brass, series 20KA: based on the provided description, this coupling is designed for water and constructed of brass with NBR seals. However, suitability for potable (drinking) water requires materials and seals certified for drinking-water contact (e.g., NSF/ANSI 61, WRAS or equivalent) and assurance that brass alloy lead content meets local regulations. The data given does not state any drinking-water certifications or low-lead compliance. Therefore, without explicit potable-water certification from the manufacturer, it should not be assumed safe for potable water applications. Obtain manufacturer confirmation or certification before using for drinking water.

Can the Quick-connection socket DN2.7 with valve, threaded, brass, series 20KA be used with non-flammable gases other than nitrogen?

Yes. The Quick-connection socket DN2.7 with valve, threaded, brass, series 20KA is specified as designed for water, air, nitrogen, and other non-flammable gases. Its materials (brass body, AISI 301/420 steel components) and NBR sealing, combined with a working pressure up to 35 bar and operating temperature range â20Â°C to +100Â°C, make it suitable for use with non-flammable gases beyond nitrogen, provided those gases are chemically compatible with brass and NBR. Before use, verify that the specific non-flammable gas does not react with brass or NBR, and confirm required purity, pressure and temperature conditions fall within the stated ratings (flow: 165 l/min at Pe = 6 bar, pressure drops as specified). If in doubt for a particular gas (e.g., oxygen, CO2, argon, helium), consult the gas supplier or manufacturer for compatibility and safety guidance.
