Is the Quick Connector DN7.8, Threaded, No Valve, Hardened Steel, Series 25KA compatible with all Eurostandard DN7.2 couplings from other manufacturers?

Yes. The Quick Connector DN7.8, Threaded, No Valve, Hardened Steel, Series 25KA is fully interchangeable with all Eurostandard DN7.2 couplings from other manufacturers, ensuring seamless compatibility and easy integration into existing systems.

Can the Quick Connector DN7.8, Threaded, No Valve, Hardened Steel, Series 25KA be used safely with fluids other than compressed air, such as oils or aggressive chemicals?

Quick Connector DN7.8, Threaded, No Valve, Hardened Steel, Series 25KA is specified for use with compressed air, liquids, and gases, so it can be used with fluids other than compressed air (including oils). Its construction—hardened, galvanized steel—offers good durability and corrosion resistance, and its working pressure (up to 35 bar) and temperature range (−20°C to +100°C) support many industrial fluids. However, safe use with aggressive chemicals cannot be guaranteed from this description alone. Compatibility depends on the specific fluid’s chemical aggressiveness, temperature, pressure, and any sealing materials (not specified). Aggressive acids, strong solvents or alkalis can attack galvanization, steel or seals and cause corrosion, swelling or leakage. Recommendation: verify chemical compatibility for your specific fluid and operating conditions. Consult the fluid and seal material compatibility charts, request manufacturer's chemical compatibility data or certification, and perform testing if needed. If aggressive chemicals are involved, consider alternative materials (stainless steel, specialized coatings, or compatible seals) or a coupling explicitly certified for the chemical in question.
