Is the CEJN 525 Hydraulic Quick Coupling, BSP Female Socket with Valve, Zinc-Nickel Steel compatible with gases using the additional O-ring?

Yes. The CEJN 525 Hydraulic Quick Coupling, BSP Female Socket with Valve, Zinc-Nickel Steel is compatible with gases when the additional O-ring is used. The product description explicitly states the additional O-ring makes it perfectly suited for gas installations, and the socket is listed as compatible with gases among other media. Ensure you select the appropriate O-ring material (NBR or Viton) based on the gas type and temperature range: NBR -30°C to +100°C; Viton -15°C to +200°C. Also confirm working pressure and safety factor meet your specific gas application requirements.

Can the CEJN 525 Hydraulic Quick Coupling, BSP Female Socket with Valve, Zinc-Nickel Steel be used with high-pressure steam or only with gases and liquids?

The CEJN 525 Hydraulic Quick Coupling, BSP Female Socket with Valve, Zinc-Nickel Steel can be used with high-pressure steam as well as with gases and liquids. The product description explicitly lists steam among compatible media and specifies a working pressure up to 450 bar (depending on diameter). Key considerations for steam use: - Sealing material: choose Viton for extended temperature range (-15°C to +200°C) if steam temperatures approach the upper limit; NBR is limited to +100°C. - Working temperature and pressure: ensure actual steam temperature and pressure remain within the coupling’s specified limits (pressure up to 450 bar and temperature per chosen seal). - Application safety: the integrated shut-off valve, safety ring and zinc-nickel steel construction support reliable high-pressure operation, but confirm compatibility with specific steam chemistry and system conditions.

Additional information

Material	CS – steel (cast iron)

The CEJN Series 525 quick coupling socket from the NORDIC RANGE is a robust solution engineered for demanding industrial and hydraulic applications. Equipped with an integrated shut-off valve and internal BSP thread, it ensures secure and efficient connections, while the additional O-ring makes it perfectly suited for gas installations. A built-in safety ring prevents accidental disconnection, enhancing reliability in critical operations. Designed exclusively for 1/4″ size, this one-sided shut-off coupling is crafted from zinc-nickel coated steel, offering exceptional durability and resistance to corrosion. With a working pressure of up to 450 bar (depending on diameter) and a safety factor of 4:1, it guarantees dependable performance under extreme conditions. The socket is compatible with a wide range of media, including hydraulic oil, water, steam, fuels, gases, and chemicals, making it highly versatile across industries. Advanced sealing options with NBR or Viton ensure optimal performance within a broad temperature range, from -30°C to +100°C for NBR and -15°C to +200°C for Viton. Flow capacity is precisely defined for a pressure drop of 3 bar, ensuring efficiency and consistency in operation.
