DIN EN853 1SN Hydraulic Hoses: Specifications, Applications, and Selection Guide

DIN EN 853 1SN is a single-wire-braid hydraulic hose type for conveying hydraulic fluids under pressure. Its typical construction combines an oil-resistant synthetic-rubber tube, one high-tensile steel-wire braid, and a protective rubber cover; the exact pressure rating depends on the hose’s nominal bore and product specification. It is used in hydraulic equipment where the application falls within the hose’s stated pressure, temperature, fluid-compatibility, and bend-radius limits. In this guide, we explain what to check before selecting or sourcing a 1SN hose, and how to provide the details a supplier needs for a useful quotation.

Key Takeaways

• 1SN identifies a hose construction with one steel-wire braid; it does not, by itself, define a working pressure for every size.
• Match the hose to the system’s maximum operating pressure, fluid, temperature, routing, and connection requirements.
• As a general product reference, 1SN hoses are commonly specified for a temperature range of approximately -40°C to +100°C, but the applicable limit must be confirmed for the selected product and fluid.
• For an accurate quote, share the nominal bore, length, assembly requirements, quantity, operating conditions, and any required documentation.

Who This Guide Is For

This guide is for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals comparing hose specifications or preparing a purchase inquiry. It is also useful if you are replacing an existing hose and need to confirm whether a 1SN construction is suitable for the equipment. We recommend treating the equipment manufacturer’s requirements and the hose supplier’s current datasheet as the controlling references for final selection. A hose that looks similar to an existing assembly may still differ in pressure rating, dimensions, or compatibility.

Understanding DIN EN 853 1SN

DIN EN 853 is a hose specification commonly used to identify certain wire-reinforced hydraulic hose constructions. The “1SN” designation refers to a compact hose construction with one steel-wire braid reinforcement layer. The braid helps the hose withstand internal hydraulic pressure, while the inner tube and outer cover serve different functions within the assembly. The designation alone is not a substitute for checking the full product data for the size and configuration you intend to buy.

Typical Construction and Materials

A typical 1SN hose has three functional layers: an inner tube, a reinforcement layer, and an outer cover. The tube is generally made from oil-resistant synthetic rubber selected for contact with the intended hydraulic fluid. A single braid of high-tensile steel wire provides pressure reinforcement, while the outer synthetic-rubber cover is designed to protect against external exposure such as abrasion and weathering. Material formulations and performance details can vary by manufacturer, so confirm them against the supplier’s documentation.

Specifications Buyers Should Confirm

When reviewing a 1SN product, check the nominal bore, outside diameter, working pressure, minimum bend radius, temperature limits, and applicable fluid compatibility. These values are size-specific or product-specific, so avoid applying a figure from one hose diameter to another. Many product ranges list nominal bores such as 6 mm, 8 mm, and 10 mm, but the available sizes should be confirmed with the supplier. For a typical 1SN range, the stated operating-temperature range may be approximately -40°C to +100°C; actual suitability depends on the hose specification, fluid, and operating conditions.

Applications and Hose-to-System Matching

1SN hoses are used in hydraulic circuits found in mobile machinery, industrial equipment, agricultural systems, and general-purpose hydraulic assemblies. Suitability depends on the requirements of the specific circuit, not just the equipment category. A hose installed near moving components may need careful routing and abrasion protection, while a fixed installation may have different layout constraints. In every case, use the equipment specification and the hose manufacturer’s data to confirm that the selected construction is appropriate.

Match the Hose to the Operating Conditions

Start with the maximum pressure the hose may experience, including relevant operating conditions identified by the equipment designer. Compare that requirement with the working-pressure rating listed for the exact hose size, and do not infer a rating from the “1SN” label alone. Next, confirm the hydraulic fluid and the expected fluid and ambient temperatures against the supplier’s compatibility information. Finally, check that the installation can meet the specified bend radius and avoid twisting, crushing, sharp edges, or unnecessary tension.

A Practical Selection Framework

1. Identify the required size. Record the nominal bore and, where available, the existing hose’s dimensions and markings. Confirm the required hose length and whether you need bulk hose or a finished assembly.
2. Document pressure and temperature. Provide the system’s operating requirements and ask the supplier to confirm the rating and temperature limits for the specific size. Do not rely on a general range where the application requires a precise limit.
3. Confirm fluid and environment. Name the hydraulic fluid and describe relevant external exposure, such as abrasion, weather, or contact with other substances. Request confirmation of compatibility when conditions are unusual or not covered by standard product information.
4. Specify fittings and assembly details. State fitting type, thread or connection standard, orientation, and assembly length where relevant. If replacing an existing assembly, provide clear measurements or photographs while still confirming dimensions independently.
5. Review documentation and order terms. Ask which product datasheet, inspection documents, packaging options, minimum order quantity, and lead-time estimate are available for the requested item. Confirm details before placing the order.

Common Selection Mistakes

A frequent mistake is selecting a hose based only on the equipment name or outer appearance. Two hoses with similar dimensions can have different pressure ratings, materials, or connection details. Another risk is assuming that a general temperature range applies to every fluid and operating condition; compatibility should be confirmed for the actual combination. Buyers should also avoid installing a hose below its specified bend radius or allowing it to rub continuously against nearby equipment.

It is also important not to treat working pressure, proof pressure, and burst pressure as interchangeable values. Each describes a different performance condition, and only the working-pressure rating should be compared with the system’s operating requirement for routine selection. If pressure surges or other demanding conditions are expected, provide that information to the equipment designer and hose supplier. They can advise whether the selected construction is suitable or whether another hose type should be evaluated.

Pricing, MOQ, and Lead Time

The price of a 1SN hose depends on factors such as size, length, order quantity, requested assembly, fittings, packaging, and destination. Minimum order quantities and lead times can also vary according to the product configuration and current availability. We recommend requesting a quotation with all technical and commercial details in one inquiry to reduce clarification cycles. For projects with multiple sizes, a size-by-size list helps the supplier check each specification and quote the requirements clearly.

Supplier Evaluation Checklist

Before choosing a supplier, confirm that the company can identify the offered hose construction and provide product information for the requested size. Ask for the relevant datasheet and clarify what inspection or quality documents can be supplied with the order; do not assume a certification or test document is included unless it is confirmed. Check that the supplier understands your fitting, length, packaging, and delivery requirements. A clear written confirmation of product details, quantity, price, and estimated lead time helps both parties reduce sourcing ambiguity.

Conclusion: Choosing the Right DIN EN853 1SN Hose

DIN EN 853 1SN is a single-steel-wire-braid hydraulic hose construction, but the correct choice depends on more than the designation. Confirm the exact size-specific pressure rating, fluid compatibility, temperature limits, bend radius, routing, and connection details before ordering. If any operating requirement is unclear, resolve it with the equipment designer or supplier rather than relying on a generic product description.
