Is the CEJN 525 hydraulic quick coupling GW BSP socket with valve, zincânickel plated steel suitable for gas installations and does its additional Oâring require special maintenance?

Yes. The CEJN 525 hydraulic quick coupling, GW BSP socket with valve, zincânickel plated steel is suitable for gas installations . the product description explicitly states the socket features an additional Oâring, making it suitable for gas applications (alongside hydraulic oil, water, steam, fuels, oils and chemicals). Regarding Oâring maintenance: the additional Oâring does not require special maintenance beyond standard practices for sealed couplings. Recommended actions: - Inspect Oâring regularly for cuts, extrusion, hardening or chemical damage. - Replace Oârings showing wear or damage; use the correct material (Viton or NBR) compatible with the gas and temperature range. - Keep sealing surfaces clean and lightly lubricated with a compatible lubricant when assembling. - Follow operating temperature limits (NBR: â30Â°C to +100Â°C; Viton: â15Â°C to +200Â°C) and max working pressure as specified (up to 450 bar depending on size). These practices ensure reliable gas-tight performance.

Can the CEJN 525 hydraulic quick coupling, GW BSP socket with valve, zincânickel plated steel be used with steam and fuels at high temperatures?

Yes - the CEJN 525 hydraulic quick coupling, GW BSP socket with valve, zinc-nickel plated steel can be used with steam and fuels at high temperatures provided you select the Viton seal version. Operating temperature ranges: NBR seals: -30Â°C to +100Â°C (not suitable for high-temperature steam/fuels); Viton seals: -15Â°C to +200Â°C (suitable for higher-temperature steam and many fuels/oils). Also confirm compatibility of Viton with the specific fuel or chemical and ensure system pressure (up to 450 bar depending on size) and application conditions are within the couplingâs specifications.

Does the CEJN 525 hydraulic quick coupling, GW BSP socket with valve, zincânickel plated steel require specific sealing material for chemical compatibility?

Yes. The CEJN 525 hydraulic quick coupling, GW BSP socket with valve, zincânickel plated steel uses supplied sealing materials (Viton or NBR) and you should choose between them based on chemical compatibility and temperature needs. NBR (â30Â°C to +100Â°C) is suitable for many hydraulic oils, water and some fuels, but has limited resistance to certain chemicals and higher temperatures. Viton (â15Â°C to +200Â°C) offers much better chemical resistance (aggressive oils, fuels and many chemicals) and higher temperature tolerance. For aggressive chemicals, high temperatures, or where compatibility is uncertain, specify the Viton Oâring or consult CEJNâs compatibility data. If you plan to use media outside the listed specifications, or specific aggressive chemicals, confirm material compatibility or request a different sealing material from the manufacturer.

Additional information

Material	CS – steel (cast iron)

The CEJN series 525 (NORDIC RANGE) quick-coupling socket with a shut-off valve and a BSP female thread. The socket has an additional O-ring, which makes it suitable for gas installations. It also has a ring to prevent accidental disconnection. As a single-shut-off quick coupling it can only be used for size 1/4″. It is intended for heavy-duty operating conditions. Application: power hydraulics (hydraulic oil), industrial (water, steam, fuels and oils, gases and chemicals). Material: zinc-nickel coated steel. Working pressure: up to 450 bar (depending on the diameter). Safety factor 4:1. Sealing: viton or NBR. Operating temperature: from -30°C to +100°C (for NBR), from -15°C to +200°C (for viton). The flow is given for a pressure drop of 3 bar.
