Can Hydraulic hose for high temperatures EN 853 2SN/HT THERMAL be used continuously at +150Â°C, or is +150Â°C only allowed for short-term exposure?

Hydraulic hose for high temperatures EN 853 2SN/HT THERMAL cannot be used continuously at +150Â°C. The specified operating temperature range is â40Â°C to +135Â°C for continuous use, with +150Â°C allowed only as a temporary/short-term exposure. For water and air the continuous maximum is +70Â°C, and additional restrictions (e.g. microâperforation for air >17 bar) apply. Continuous operation at +150Â°C would exceed the hoseâs rated continuous temperature and is not recommended.

Is Hydraulic hose for high temperatures EN 853 2SN/HT THERMAL suitable for continuous use at +135Â°C, and what limits apply to the temporary +150Â°C peak?

Hydraulic hose for high temperatures EN 853 2SN/HT THERMAL is suitable for continuous use at +135Â°C - its specified operating range is â40Â°C to +135Â°C. The +150Â°C is only a temporary peak allowance; it should not be used continuously at that temperature. No explicit duration is given in the description, so peak exposure should be minimized and limited to short events to avoid accelerated aging or loss of performance. Note additional service limits: for water and air maximum operating temperature is +70Â°C, and for compressed air above 17 bar the outer layer requires micro-perforation. Ensure working pressure for your hose diameter (80â400 bar) is respected at elevated temperatures.

Does Hydraulic hose for high temperatures EN 853 2SN/HT THERMAL require special fittings for +135Â°C continuous use?

Hydraulic hose for high temperatures EN 853 2SN/HT THERMAL does not inherently require special fittings solely because of its +135Â°C continuous rating, provided the chosen fittings and assemblies are specified and rated for the same temperature range and the intended media/pressure. Key points: - Use fittings and crimping methods compatible with double steel-braid hoses (EN 853 2SN type). Standard 2SN fittings (socket and nipple) designed for steel-braid hoses are appropriate if they match hose dimensions and working pressures (80â400 bar depending on diameter). - Ensure fittings, seals and any ferrules are rated for continuous operation at +135Â°C (and up to +150Â°C temporarily). Many standard fittings use seal materials (elastomers, PTFE) that have lower temperature limits; select materials (e.g., high-temperature elastomers, metal-to-metal or PTFE seals) specified for â¥+135Â°C. - Consider outer cover behavior at elevated temperature: the outer oil- and ozone-resistant rubber must not degrade at the service temperature; confirm compatibility with chosen coupling materials and clamping/crimping procedures. - For water and air services note the hose max operating temperature is +70Â°C; do not use +135Â°C fittings selection as justificationâsystem limits differ by media. For air above 17 bar, follow the micro-perforation requirement for the outer layer and verify coupling method does not interfere. - Validate assembly: crimping dimensions, crimping tool settings and inspection must follow manufacturer instructions for the EN 853 2SN/HT THERMAL to ensure pressure rating and fatigue life (manufacturer confirms 400,000 impulse cycles). - When in doubt, confirm with hose manufacturer/supplier and specify fittings explicitly approved for EN 853 2SN/HT THERMAL at +135Â°C continuous use. Conclusion: No exotic mechanical fitting type is automatically required, but fittings and seals must be selected and qualified for continuous +135Â°C operation and for the hoseâs pressure/media limits.
