Can EN 857 2SC double braided steel hydraulic hose be used with biodegradable hydraulic fluids and maintain its pressure ratings?

Yes . EN 857 2SC double braided steel hydraulic hose can generally be used with many biodegradable hydraulic fluids and retain its pressure ratings, but with important conditions. Why itâs feasible: - Construction: inner layer of synthetic rubber and double steel braid reinforcement provide the mechanical strength that determines working pressure (165â400 bar depending on diameter). That mechanical reinforcement is not altered by most biodegradable fluids, so pressure ratings are typically maintained. - Temperature range: operating â40Â°C to +100Â°C (temporarily +125Â°C) covers the service window for many biodegradable fluids; as long as fluid temperature stays within this range, hose performance and pressure ratings remain valid. Caveats and required checks: - Chemical compatibility: âsynthetic rubberâ covers many compounds (e.g., NBR, HNBR, EPDM, etc.). Some biodegradable fluids (especially esters.HEES, HETG, HEPG) can attack certain rubbers or cause swelling/softening that degrades the inner tube and shortens life. Verify the specific hose tube compound compatibility with the exact biodegradable fluid (manufacturer chemical-resistance data). - Application conditions: elevated temperatures, pressure spikes, aggressive additives, or prolonged exposure may affect the inner tube and lead to premature failure even if braid strength is adequate. - Validation: perform supplier confirmation or compatibility testing, and follow manufacturer recommendations. Where possible, request manufacturer approval or use a hose explicitly specified for the particular biodegradable fluid. Conclusion: EN 857 2SC double braided steel hydraulic hose can maintain its pressure ratings with biodegradable fluids provided the hoseâs inner rubber compound is compatible with the specific fluid and operating conditions (temperature, pressure spikes, additives) are within rated limits. Obtain manufacturer confirmation or test to be certain.

Is EN 857 2SC double braided steel hydraulic hose compatible with glycol-based or phosphate ester fireâresistant fluids?

EN 857 2SC double braided steel hydraulic hose Format is generally intended for mineral-oil based hydraulic fluids. The provided specification (synthetic rubber inner/outer, double steel braid, working pressures 165â400 bar, temperature range -40Â°C to +100Â°C/briefly +125Â°C) does not state compatibility with glycol-based or phosphate ester (HF) fireâresistant fluids. Glycol-based and phosphate ester fluids have different chemical properties and can attack standard synthetic rubbers and hose adhesives; phosphate esters in particular often require hoses specifically approved for HF fluids. Therefore you should not assume compatibility - consult the hose manufacturerâs chemical compatibility data sheet or obtain a version of EN 857 2SC explicitly rated for glycol-based or phosphate ester fluids before use.

Can EN 857 2SC double braided steel hydraulic hose be used in low-temperature applications down to -40Â°C without performance loss?

Yes. EN 857 2SC double braided steel hydraulic hose can be used in low-temperature applications down to â40Â°C without loss of specified performance, provided service conditions fall within the hoseâs rated limits. The product description lists an operating temperature range from â40Â°C to +100Â°C (temporary up to +125Â°C), which indicates the hose materials (inner and outer synthetic rubber and double steel braid reinforcement) are suitable for continuous use at â40Â°C. Important practical notes: - Ensure fluid compatibility at low temperature: hydraulic fluid viscosity increases at â40Â°C, which can affect system pressure, flow, and seal behaviour. The hose itself meets the temperature rating, but system components and fluid must also be appropriate for â40Â°C. - Flexibility and bend radius: although designed for increased flexibility and reduced OD/weight, rubber can stiffen at very low temperatures, so verify required bend radius and dynamic movement under cold conditions. - Pressure and dynamic loads: working pressure ratings (165â400 bar depending on diameter) apply across the specified temperature range; confirm your pressure duty, including pressure spikes, is within the hoseâs rated limits at â40Â°C. - Installation and handling: avoid sharp bends, abrasion and torsion during installation, and allow for thermal contraction. If the hose will be exposed to repeated flexing in extreme cold, consider additional testing or a cold-cycle qualification. Conclusion: EN 857 2SC double braided steel hydraulic hose is rated for operation down to â40Â°C, so it can be used at that temperature if the hydraulic fluid, system design, pressure demands and installation practices are all compatible with low-temperature operation.
