Can Single braided steel hydraulic hose EN 853 1SN S be used for compressed air above 17 bar without micro-perforation of the outer layer?

No . Single braided steel hydraulic hose EN 853 1SN S must not be used for compressed air above 17 bar without micro-perforation of the outer layer. According to the provided description, for air pressures above 17 bar the outer cover requires micro-perforation. Even though the hoseâs working pressure range (40â250 bar depending on diameter) and materials are suitable for high pressures, the specification explicitly mandates micro-perforation of the outer layer for air above 17 bar to prevent issues (e.g., trapped air expansion, cover delamination, or safety hazards). Use the hose only with the required micro-perforated outer layer when operating with compressed air over 17 bar.

Is Single braided steel hydraulic hose EN 853 1SN S suitable for potable water applications at +70Â°C without additional treatment?

No. Single braided steel hydraulic hose EN 853 1SN S is not suitable for potable (drinking) water applications at +70Â°C without additional treatment. The hose construction uses black oilâresistant synthetic rubber for the inner layer (designed for hydraulic fluids), which is not certified for potable water contact. Although the operating temperature limit for water is +70Â°C, suitability for drinking water requires materials and certifications ensuring hygienic, nonâtoxic, and taste/odor safe contact; those are not provided in the general-purpose EN 853 1SN description. To use for potable water at +70Â°C you would need a hose specifically rated and certified for drinking water (WRAS/ACS/NSF or equivalent) or an approved foodâgrade inner liner and documentation.

Can Single braided steel hydraulic hose EN 853 1SN S be used continuously at +100Â°C with oil-based fluids?

Single braided steel hydraulic hose EN 853 1SN S cannot be recommended for continuous use at +100Â°C with oil-based fluids. The hoseâs specified operating temperature range is â40Â°C to +100Â°C, with +120Â°C allowed only temporarily. âTemporarilyâ implies short-term excursions above +100Â°C rather than sustained continuous operation. Continuous exposure at the upper limit risks accelerated ageing of the inner and outer oil-resistant synthetic rubber, loss of mechanical properties, reduced burst and working pressure margins, and premature failure. If your application requires continuous operation at +100Â°C, you should: - Confirm with the hose manufacturer/supplier that continuous service at +100Â°C with the specific oil type is approved (manufacturer approval supersedes general specs). - Consider specifying a hose rated for continuous service at or above +100Â°C (or with higher temperature elastomers). - Verify compatibility with the particular oil (some oils at high temperature may be more aggressive). - Implement a conservative pressure/temperature derating and inspect more frequently for signs of ageing. In summary: Single braided steel hydraulic hose EN 853 1SN S is rated to +100Â°C as an upper operating limit but +120Â°C only temporarily. continuous use at +100Â°C is not generally advised without manufacturer confirmation and additional risk mitigation.
