Is the Quick-connect air socket DN7.2 Eurostandard with valve, hose fitting, 35 bar compatible with other Eurostandard DN7.2 ÷ 7.8 couplings?

Yes. The Quick-connect air socket DN7.2 Eurostandard with valve, hose fitting, 35 bar is fully compatible and interchangeable with other Eurostandard couplings in the DN7.2 ÷ 7.8 range. Made of durable brass with NBR seals, rated to 35 bar and offering 1100 l/min flow (Pe=6 bar, Δp=0.5 bar), it fits standard Eurostandard profiles and integrates smoothly into existing pneumatic systems. Available in three hose-fitting variants (corrugated fitting; thermoplastic fitting with nut; thermoplastic fitting with nut and protective spring), it provides flexible installation options while maintaining reliable sealing and performance across −20°C to +100°C.

Can the Quick-connect air socket DN7.2 Eurostandard with valve, hose fitting, 35 bar be used safely with oxygen or other flammable gases?

No. The Quick-connect air socket DN7.2 Eurostandard with valve, hose fitting, 35 bar is specified for air, nitrogen, and other non-flammable gases. It is made of brass with NBR seals and rated for up to 35 bar, but the product description explicitly limits use to non-flammable gases. Oxygen and other flammable or oxidizing gases pose special compatibility and safety hazards (material reactions, increased fire risk, contamination of seals/lubricants). Use with oxygen or flammable gases requires components specifically certified and cleaned for oxygen service and compatible materials and seals; NBR and standard brass fittings are generally not suitable. Therefore do not use this coupling with oxygen or flammable gases unless the manufacturer provides explicit oxygen/flammable-gas certification and compatible materials.
