Is the Brass DN2.7 Quick-Connect Socket with Valve and Hose End, Series 20KA compatible with nitrogen and other non-flammable gases?

Yes. The Brass DN2.7 Quick-Connect Socket with Valve and Hose End, Series 20KA is specified for use with nitrogen and other non-flammable gases. Its construction (brass body, AISI 301 springs/rings, AISI 420 balls, NBR seals), rated working pressure up to 35 bar, temperature range −20°C to +100°C, and stated compatibility with air, nitrogen and other non-flammable gases confirm suitability for those media.

Can the Brass DN2.7 Quick-Connect Socket with Valve and Hose End, Series 20KA withstand continuous operation at 35 bar in high-cycle industrial applications?

Yes. The Brass DN2.7 Quick-Connect Socket with Valve and Hose End, Series 20KA is specified for a working pressure of up to 35 bar and is manufactured from robust materials (brass body, AISI 301 springs/rings, AISI 420 balls, NBR seals) with a temperature rating of -20°C to +100°C. These design features, combined with its single shut-off valve and proven flow performance, make it suitable for continuous operation at 35 bar in high‑cycle industrial applications, provided the application uses approved media (water, air, nitrogen, other non‑flammable gases) and operating conditions do not exceed the stated temperature, pressure, or chemical compatibility limits.
