Is the Mini air hose coupling socket with valve DN2.7, threaded nickel-plated brass, 16 bar compatible with RECTUS 20 plugs and other DN 2.7 plug profiles?

Yes. The Mini air hose coupling socket with valve DN2.7, threaded nickel-plated brass, 16 bar is fully compatible with RECTUS 20 plugs and other DN 2.7 plug profiles that share the same plug profile. The description explicitly states it is fully interchangeable with RECTUS 20 and other DN 2.7 quick-connects, so you can use RECTUS 20 plugs or other matching DN 2.7 plugs without issues.

Can the Mini air hose coupling socket with valve DN2.7, threaded nickel-plated brass, 16 bar be used with breathable gases like oxygen or only with air and nitrogen?

Mini air hose coupling socket with valve DN2.7, threaded nickel-plated brass, 16 bar is specified for pneumatic applications with air, nitrogen, and other non-flammable gases. The description highlights NBR seals, nickel‑plated brass body, stainless steel pins and spring, operating range −20°C to +100°C, and maximum pressure 16 bar, but does not state compatibility with breathable medical gases such as oxygen. Because oxygen is a highly reactive (oxidizing) gas that can interact with certain materials and increase fire risk, components must be qualified for oxygen service (materials, cleaning, lubrication and certification). NBR, brass and typical lubricants used in pneumatic couplings often are not approved for oxygen use. Therefore, unless the manufacturer explicitly certifies the Mini air hose coupling socket with valve DN2.7, threaded nickel-plated brass, 16 bar for oxygen/breathable gas service and provides appropriate oxygen-cleaning and material compatibility documentation, it should be used only with air, nitrogen and other non‑flammable gases — not oxygen or breathable medical gases.
