Is the CEJN 525 hydraulic quick coupling, plug with GW BSP without valve, galvanized steel compatible with hydraulic oil at 450 bar and available with Viton seals?

Yes. The CEJN 525 hydraulic quick coupling, plug with GW BSP without valve, galvanized steel is suitable for hydraulic oil at pressures up to 450 bar (depending on diameter) and is available with Viton seals. The coupling is designed for hydraulic power (hydraulic oil), constructed from zincânickel coated steel for heavyâduty use, offers a 4:1 safety factor, and the Viton sealing option supports an operating temperature range of â15Â°C to +200Â°C.

Can the CEJN 525 hydraulic quick coupling, plug with GW BSP without valve, galvanized steel be used with steam at elevated temperatures?

Yes - the CEJN 525 hydraulic quick coupling, plug with GW BSP without valve, galvanized steel can be used with steam at elevated temperatures provided you select the Viton seal version and remain within the stated limits. Viton seals permit operation up to +200Â°C; NBR is limited to +100Â°C and is not suitable for higher-temperature steam. Also confirm compatibility of zinc-nickel plated steel with your steam chemistry and pressures (working pressure up to 450 bar depending on size) and ensure the application respects the manufacturerâs safety factor and installation guidelines. If steam temperatures approach or exceed +200Â°C, seek alternative materials or consult CEJN for guidance.

Q: Can the CEJN 525 hydraulic quick coupling, plug with GW BSP without valve, galvanized steel be used with gases and chemicals?

Yes. the CEJN 525 hydraulic quick coupling, plug with GW BSP without valve, galvanized steel can be used with gases and many chemicals, according to the manufacturerâs application range. Key considerations: - Intended applications: the product description explicitly lists gases and chemicals among suitable industrial media (alongside hydraulic oil, water, steam, fuels and oils). - Materials and seals: body is steel with zincânickel coating; sealing options are Viton (FKM) or NBR. Viton provides broader chemical compatibility and higher temperature resistance (-15Â°C to +200Â°C) than NBR (-30Â°C to +100Â°C). Select Viton for aggressive chemicals and elevated temperatures. - Pressure and safety: rated working pressure up to 450 bar (depending on diameter) with a 4:1 safety factor. Confirm your system pressure and coupling diameter meet this rating. - Compatibility check: while the coupling is listed for gases and chemicals, final suitability depends on the specific gas or chemical, concentration, temperature, and operating pressure. Check chemical compatibility with steel (zincânickel coating) and chosen seal material (Viton or NBR) for the exact media. - Additional precautions: ensure appropriate sealing, consider leak risk with gases (use correct installation and testing), and verify any regulatory/safety requirements for your application. If you provide the specific gas or chemical, temperature and pressure, I can advise on compatibility with the zincânickel steel body and available seal materials.
