DIN EN 853 1SN is a hydraulic hose type with a synthetic-rubber inner tube, one layer of high-tensile steel-wire braid, and a protective rubber cover. It is commonly selected for hydraulic circuits where a single wire-braid reinforcement meets the required pressure and routing conditions. To choose correctly, match the hose’s nominal bore, working pressure, temperature range, fluid compatibility, and minimum bend radius to the equipment—not just the 1SN designation. At XINCHI, we recommend confirming these details against the product datasheet and the assembly requirements before requesting a quotation.

This guide is intended for procurement teams, hydraulic equipment manufacturers, maintenance departments, and distributors evaluating DIN EN 853 1SN hose. It provides a practical overview of construction, specifications, application fit, and supplier questions. It is not a substitute for the applicable standard, equipment documentation, or a manufacturer’s datasheet. Where exact limits matter, verify them for the specific hose size and assembly.
The 1SN designation identifies a hose construction with one braided layer of steel-wire reinforcement. The inner tube carries the hydraulic fluid, the reinforcement helps contain pressure, and the outer cover protects the assembly from its operating environment. The letters and numbers identify a construction category; they do not, by themselves, state the working pressure for every size or confirm that a hose is suitable for every fluid.
EN 853 covers wire-braid-reinforced hydraulic hoses, including 1SN and 2SN constructions. A 1SN hose has one steel-wire braid, while 2SN has two. The additional braid in 2SN does not make it the automatic choice: buyers should compare pressure requirements, flexibility, dimensions, and the machine manufacturer’s specifications for the intended application.
A typical 1SN hose uses an oil-resistant synthetic-rubber inner tube and a synthetic-rubber cover designed to resist relevant environmental exposure. Exact compound formulations and resistance properties vary by product. Check the supplier’s documentation for compatibility with the hydraulic fluid, external oils, abrasion, ozone, and other conditions at the installation site.
Many EN 853 1SN products are specified for a working temperature range of approximately -40°C to +100°C, but the permitted range can depend on the hose design and fluid. Treat this as a specification to verify, not a blanket guarantee for every product or continuous-duty condition. A temperature outside the documented range may affect hose life or suitability, so review both fluid and ambient temperatures.
Before comparing quotations, collect the operating and installation requirements in one place. The hose standard defines a construction family, while the product datasheet supplies the size-specific values needed for selection. Use the table below as a checklist; do not infer a rated limit from a nominal size alone.
| Specification | What to confirm | Why it matters |
|---|---|---|
| Nominal bore | Dash size or DN, plus required inside diameter | Influences flow capacity, velocity, and connection fit |
| Working pressure | Rated pressure for the selected hose size and assembly | Must meet or exceed the system’s documented operating requirement |
| Temperature | Permitted fluid and ambient temperature ranges | Helps ensure the hose materials suit real operating conditions |
| Bend radius | Minimum radius for the selected size | Prevents routing that is tighter than the product permits |
| End connections | Fitting type, thread, orientation, and assembly method | Ensures compatibility with the equipment and installation |
| Cover and fluid compatibility | Resistance needs and any special environmental exposure | Supports selection for the actual application, not a generic use case |
Pressure ratings are size-specific and must be taken from the manufacturer’s data. For example, 1SN products may be offered in nominal sizes from DN 6 to DN 51, but the rating for a smaller bore cannot be applied to a larger one. Also distinguish working pressure from burst pressure: burst figures are not operating targets. Confirm the allowable pressure for the finished hose assembly, including its fittings.

1SN hose can be considered for hydraulic lines on mobile and industrial equipment when its pressure, temperature, fluid, and routing specifications match the system. Examples may include equipment power circuits and general hydraulic connections, but the machine maker’s requirements take priority. High pressure spikes, frequent flexing, external damage, or severe environmental exposure can change the selection decision.
A frequent mistake is choosing by outside appearance or the term “1SN” alone. The designation does not replace checks for size-specific pressure, bend radius, or fluid compatibility. Another risk is using a hose with a nominal bore that does not suit the required flow; ask your hydraulic engineer or equipment supplier to confirm sizing where flow velocity is critical.
Buyers should also avoid treating EN 853 1SN and other hose standards as automatically interchangeable. Similar-looking constructions can have different dimensions, performance limits, or assembly requirements. Do not use a burst rating as a working-pressure rating, and do not assume that a hose suitable for one fluid or temperature is suitable for another.
Pricing generally depends on factors such as hose size, order quantity, required length, fittings, packaging, and any documentation or customization requested. Minimum order quantities and lead times vary by supplier, product configuration, and current availability; they should be confirmed for each inquiry rather than assumed from a catalogue listing. If the purchase includes assembled hoses, provide the full fitting and length specification to help suppliers quote comparable products.
For a useful quotation, share the target standard and size, required quantity, working conditions, assembly details, destination, and any document requirements. If a project has multiple hose lengths or fitting combinations, a line-by-line schedule reduces ambiguity. Ask the supplier to state the quoted product’s pressure rating and temperature limits against the requested specification.
DIN EN 853 1SN is a single-steel-wire-braid hydraulic hose construction, and it can be a suitable option when its size-specific ratings and materials match the system. The key checks are bore, working pressure, temperature, fluid compatibility, bend radius, routing, and end connections. The standard designation alone is not enough to approve a hose for service.
To move from evaluation to sourcing, prepare your operating conditions and connection details, then compare supplier datasheets against the equipment requirements. XINCHI can review your DIN EN 853 1SN inquiry and help clarify the product information needed for evaluation and quotation. Send the required size, quantity, application conditions, fitting details, and destination so we can respond with a more relevant offer.
