Description
EN853 1SN / 2SN 135C Hydraulic Hose technical overview
EN853 1SN / 2SN 135C hydraulic hose for higher temperature mobile hydraulic systems and maintenance replacement in heavy equipment.
Catalog-based construction and application
| Tube | Oil resistant synthetic rubber tube. |
|---|---|
| Reinforcement | One or two high tensile steel wire braids by pressure requirement. |
| Cover | Wrapped abrasion and weather resistant synthetic rubber cover for 135C service grade. |
| Working pressure | Catalog selection range follows braided hose sizes: 25 MPa to 8.8 MPa by size. |
| Temperature | Up to +135 C grade; confirm continuous and peak service temperature. |
| Standard / reference | EN 853 1SN / 2SN reference; Indo Hydraulics catalog standard selection includes EN 853. |
| Application | Hydraulic oil lines near engine bays, palm oil equipment, loaders, excavators and compact routing. |
| Fitting compatibility | Matched non-skive or skive ferrules with BSP, JIC, ORFS, NPT or DIN metric fittings. |
Size and pressure reference
The table below follows the dimensional pattern shown in the Indo Hydraulics hose catalog. Final hose assembly selection should confirm fluid, impulse load, route radius and crimp fitting series.
| I.D. inch | I.D. mm | O.D. mm | W.P. MPa / psi | Bend radius mm | Weight kg/m |
|---|---|---|---|---|---|

Selection notes for buyers
- Use for mobile machinery, palm oil equipment, compact routing and maintenance replacement.
- Confirm bend radius around cylinders, pumps, valve blocks and moving arms before assembly.
- Match ferrule and insert series to hose construction to reduce leakage and pull-off risk.
FAQ
Can this hose be supplied as a crimped hose assembly?
Yes. Indo Hydraulics can match hose, ferrule and fitting type for replacement or project supply, including BSP, JIC, ORFS, NPT and DIN metric connection patterns.
Which size should be stocked for maintenance?
Fast-moving maintenance sizes usually depend on the equipment population. For mobile hydraulic lines, 1/4 inch to 1 inch sizes are common; for industrial transfer hose, 1/2 inch to 4 inch sizes are often requested.
How should pressure be confirmed?
Choose by working pressure, burst margin, bend radius, temperature and fluid compatibility. Do not select by hose size alone.
