Is the CEJN 525 hydraulic quick coupling plug, BSP female thread with valve & eliminator, galvanized steel compatible with hydraulic oil and rated for 450 bar working pressure?

Yes. The CEJN 525 hydraulic quick coupling plug, BSP female thread with valve & eliminator, galvanized steel is designed for hydraulic power applications with hydraulic oil and is rated for working pressures up to 450 bar (depending on diameter). It features a shut-off valve and NBR seals, is made from high-strength steel with a zinc-nickel coating, and is suitable for a wide temperature range (-30°C to +100°C).

Can the CEJN 525 hydraulic quick coupling plug, BSP female thread with valve & eliminator, galvanized steel be used with steam and chemicals within its specified temperature range?

Yes. The CEJN 525 hydraulic quick coupling plug, BSP female thread with valve & eliminator, galvanized steel can be used with steam and many chemicals as long as operations remain within its specified limits. The product description explicitly lists steam and chemicals among compatible media and specifies a wide operating temperature range of -30°C to +100°C and an NBR sealing system. Note the following constraints: - Temperature: must not exceed +100°C or fall below -30°C. - Sealing material: NBR (nitrile) may be attacked by certain chemicals (strong acids, ketones, some chlorinated solvents, and aromatic hydrocarbons) or by prolonged exposure to high-temperature steam — verify chemical compatibility with NBR. - Pressure: rated up to 450 bar depending on size; ensure operating pressure does not exceed the coupling’s rating. - Corrosion: galvanized (zinc-nickel) steel offers good resistance, but aggressive chemical environments may require additional verification or alternative materials. Recommendation: confirm the specific chemical(s) and their concentrations and the exact steam conditions (temperature, pressure, wet/dry) against NBR and galvanized steel compatibility data before use.
