Can the Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series be used with steam at 10 bar and what seal (NBR or Viton) is recommended?

Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series can be used with steam at 10 bar . the product specification lists working pressure up to 50 bar and explicitly notes "for steam 10 bar." For sealing material choice: Viton (FKM) is recommended for steam service because of its higher maximum operating temperature (+200Â°C) and better chemical/thermal resistance compared with NBR, whose limit is +100Â°C. Use NBR only if the steam temperature is known to remain below NBRâs limit and cost or compatibility considerations favor it.

Is the Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series suitable for high-flow air applications up to 6 bar?

Yes. Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series is suitable for high-flow air applications up to 6 bar: its air performance is specified at 1650 l/min at Pe = 6 bar (Îp = 0.5 bar), it supports working pressures up to 50 bar, and offers high flow rates with compact dimensions. Ensure compatible sealing material (NBR or Viton) and note operating temperature limits.

Does the Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series resist corrosion in maritime environments?

Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series offers high corrosion resistance per its description, but suitability for maritime environments depends on exposure severity. Chrome-plated brass provides improved resistance compared with plain brass and is suitable for many wet and humid conditions (water, oils, fuels, steam). However, in aggressive marine settings (continuous salt spray, sea water immersion, brackish or highly corrosive atmospheres) chrome-plated brass can suffer pitting, dezincification or coating degradation over time. For harsh maritime use, the AISI 316 steel version is significantly better: AISI 316 is marine-grade stainless steel with much higher resistance to chloride-induced corrosion and is the recommended choice where saltwater exposure, spray, or prolonged humidity are expected. Additional considerations: - Sealing material: Viton resists higher temperatures and many chemicals better than NBR and can perform better in marine environments; NBR is more limited. - Operating conditions: Steam rating, pressures and temperatures are suitable for listed fluids, but prolonged salt exposure can affect plated surfaces and threads. - Maintenance and installation: Regular rinsing, inspection, and use of compatible thread sealants help extend life in maritime settings. Conclusion: Quick connector DN9.5 with valve, threaded, chrome-plated brass, 1800N series may resist mild maritime conditions, but for reliable long-term corrosion resistance in marine environments choose the AISI 316 steel variant and Viton seals.

Additional information

Material	SS – stainless steel

Universal quick coupling plug with valve DN9.5, with external NPT thread or internal BSP thread. Double shut-off, standard TEMA 1800N, popular in the Scandinavian market, designed primarily for liquids (for water, steam, oils, and fuels) to prevent leaks during disconnection. It features high corrosion resistance and large flow rates with small external dimensions. couplings of series 1800N should not be combined with series 1800. Material: chrome-plated brass or AISI 316 steel. Performance: 34.7 l/min (Δp = 1 bar, Kv = 2.08 – water), 1650 l/min (Pe=6 bar, Δp=0.5 bar – air). Working pressure: 50 bar (for steam 10 bar). Sealing: NBR or Viton. Operating temperature: from -20°C to +100°C (NBR), from -15°C to +200°C (Viton).
