Can the DN12 two-way quick-connection plug, threaded, nickel-plated brass, series 57KB, handle both liquid and gas at 35 bar working pressure?

Yes. The DN12 two-way quick-connection plug, threaded, nickel-plated brass, series 57KB is specified for both liquid and gas media with a working pressure of 35 bar, so it can handle both types of media at that pressure. Key relevant specs: material nickel-plated brass, sealing NBR, operating temperature â20Â°C to +100Â°C, and declared working pressure 35 bar. Note: ensure media compatibility with NBR seals and the brass body (e.g., some aggressive chemicals, ammonia or hydrogen sulfide may be unsuitable), and consider application-specific safety factors, temperature effects on pressure ratings, and any applicable standards or certifications for gas service before final use.

Is the DN12 two-way quick-connection plug, threaded, nickel-plated brass, series 57KB suitable for use with potable water and compressed air?

Yes. The DN12 two-way quick-connection plug, threaded, nickel-plated brass, series 57KB is suitable for both potable water and compressed air within its specified limits. It is rated for liquids and gases, working pressure up to 35 bar, flow rates shown (air: 3300 l/min at Pe=6 bar, Îp=0.5 bar; water: 73.5 l/min at Îp=1 bar, Kv=4.4). Material is nickel-plated brass with NBR sealing and operating temperature -20Â°C to +100Â°C. Note: confirm compatibility with local drinking-water regulations and NBR suitability for any specific water treatment chemicals; for potable use certification may be required.

Does the DN12 two-way quick-connection plug, threaded, nickel-plated brass, series 57KB support temperatures down to -20Â°C during continuous operation?

Yes. The DN12 two-way quick-connection plug, threaded, nickel-plated brass, series 57KB supports continuous operation down to â20Â°C. The product specification lists an operating temperature range from â20Â°C to +100Â°C, and the seals are NBR (nitrile rubber), which is compatible with that lower limit for typical continuous use. Ensure medium-specific compatibility and any dynamic conditions (e.g., rapid temperature cycling or extreme pressures) are acceptable for your application, as those can affect seal performance.
