Is EN 853 2SN double braided steel hydraulic hose suitable for use with compressed air above 17 bar, and is micro-perforation of the outer layer required?

Yes . EN 853 2SN double braided steel hydraulic hose can be used with compressed air above 17 bar, but only if the outer layer is micro-perforated. The hose specifications state: working pressure ranges from 165 to 400 bar (depending on diameter), suitable materials (oilâresistant synthetic rubber inner and outer layers) and temperature limits. However, for air service above 17 bar the note explicitly requires microâperforation of the outer layer. Ensure the hose diameter and exact model meet the required working pressure and follow manufacturer installation and safety recommendations.

Can EN 853 2SN double braided steel hydraulic hose be used for potable water applications and are sanitization requirements different?

No - EN 853 2SN double braided steel hydraulic hose is a general-purpose hydraulic hose with oil-resistant synthetic rubber inner and outer layers, designed for hydraulic fluids, water and air up to specified limits. It is not intended or certified for potable (drinking) water use: materials are not guaranteed food-contact safe, and construction may harbor contaminants. Sanitization requirements for potable water (food-grade materials, smooth inner surfaces, traceability, regulatory approvals, clean assembly and disinfection procedures) differ substantially from hydraulic hose practice. If you need a hose for drinking water, use a dedicated potable-water approved hose with appropriate certifications and follow required sanitization and installation rules.

Can EN 853 2SN double braided steel hydraulic hose be used continuously at +125Â°C and what are the limitations?

EN 853 2SN double braided steel hydraulic hose cannot be used continuously at +125Â°C. According to the specification, its normal operating temperature range is -40Â°C to +100Â°C, with +125Â°C allowed only temporarily. Continuous operation at +125Â°C exceeds the recommended maximum continuous temperature and risks accelerated aging, loss of mechanical properties of both inner and outer synthetic rubber layers, reduced burst and fatigue resistance of the hose assembly and fittings, and possible hose failure under pressure. Limitations and practical considerations: - +125Â°C is permitted only for short, temporary exposures; define âtemporaryâ per manufacturer guidance (typically minutes to hours, not continuous duty). - Continuous service above +100Â°C will shorten service life significantly and may void warranties or safety approvals. - Working pressure ratings (165â400 bar depending on diameter) apply within the specified temperature range; at elevated temperatures allowable pressure may be reducedâconsult the manufacturer for temperature/pressure derating. - For water and air service the maximum operating temperature is +70Â°C; therefore EN 853 2SN hose must not be used with water or air continuously at +125Â°C. - For compressed air above 17 bar, micro-perforation of the outer layer is required; elevated temperatures may affect this requirement and sealing/integrity. - If your application requires frequent or continuous exposure to +125Â°C consider alternative hoses rated for continuous high temperatures or use thermal protection (insulation, cooling) and frequent inspection/replacement intervals. For safe use, obtain manufacturer confirmation on allowable exposure duration at +125Â°C and any pressure derating or installation/inspection requirements.
