Is the Quick connector DN7.4 without valve, with hose socket, hardened steel, 1300 series safe to use with oils or only for compressed air and gases?

Quick connector DN7.4 without valve, with hose socket, hardened steel, 1300 series is designed primarily for compressed air and gases. Specified material (hardened galvanized steel), working pressure (35 bar) and operating temperature (-20Â°C to +100Â°C) indicate mechanical suitability for pneumatic media. However the description does not state chemical compatibility with oils or hydraulic fluids, nor does it mention seals/materials resistant to oils. Because it is a free-flow plug without a valve and is specified for air/gases only, you should assume it is not certified for oil/hydraulic service without manufacturer confirmation. Using it with oils could risk seal degradation, leakage or incompatibility. Recommendation: contact the manufacturer or supplier to confirm oil compatibility and suitability for hydraulic applications, or select a coupling explicitly rated for oil/hydraulic use.

Can the Quick connector DN7.4 without valve, with hose socket, hardened steel, 1300 series be used with corrosive gases or only with standard compressed air?

Quick connector DN7.4 without valve, with hose socket, hardened steel, 1300 series is designed primarily for compressed air and gases. Its material is hardened galvanized steel and the spec does not state chemical or corrosion-resistant construction. Therefore it is suitable for standard compressed air and non-corrosive gases, but not recommended for corrosive gases or aggressive chemical environments without confirmation from the manufacturer or use of corrosion-resistant variants. For corrosive gases choose couplings specified for chemical resistance.
