DIN EN853 2SN Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN 853 2SN Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN 853 2SN is a reinforced hydraulic hose type designed for conveying hydraulic fluids under pressure. It typically has an oil-resistant synthetic-rubber tube, two braided high-tensile steel-wire reinforcement layers, and a weather- and abrasion-resistant rubber cover. Buyers should confirm the exact working pressure, temperature limits, dimensions, and fluid compatibility against the manufacturer’s datasheet for the selected size. This guide explains the construction, common applications, and practical checks we recommend before requesting a quotation.

Key Takeaways
- 2SN identifies a two-wire-braid construction; pressure capacity depends on hose size and the specific product specification.
- Common product ranges cover nominal bores from approximately DN 6 to DN 51, but availability varies by manufacturer.
- Temperature capability is often specified around -40 °C to +100 °C for suitable hydraulic oils, subject to fluid type and product datasheet.
- Choose the hose by system pressure, fluid, temperature, routing, end connections, and applicable requirements—not by the 2SN designation alone.
Who This Guide Is For
This guide is for hydraulic equipment manufacturers, maintenance teams, distributors, and purchasing professionals comparing hose options for industrial or mobile machinery. It is especially useful when a drawing or bill of materials calls for EN 853 2SN and the buyer needs to verify whether a proposed hose is suitable. It can also help buyers prepare a complete RFQ, reducing clarification cycles around size, pressure, and fittings.
What Is a DIN EN 853 2SN Hydraulic Hose?
DIN EN 853 2SN describes a type of high-pressure hydraulic hose associated with the EN 853 specification. Its “2SN” construction uses two braided layers of steel wire to reinforce the hose against internal pressure. The inner tube carries the fluid, while the outer cover provides a protective barrier against external conditions such as abrasion and weather exposure.
Construction and Materials
The tube is generally made from synthetic rubber selected for compatibility with specified hydraulic fluids. The reinforcement consists of two steel-wire braids, and the cover is typically rubber formulated for protection in the intended operating environment. Exact compounds, cover properties, and dimensional tolerances can differ between products, so request the current technical datasheet rather than assuming all hoses marked 2SN are identical.
Specifications to Check
| Specification | What to confirm | Why it matters |
|---|---|---|
| Nominal bore and dimensions | Inside diameter, outside diameter, and tolerance for the required size | Affects flow, fit, and compatibility with hose fittings |
| Working pressure | Rated pressure for the exact diameter and product construction | Must meet the system’s maximum operating pressure and applicable design requirements |
| Temperature range | Permitted fluid and ambient temperature limits | Heat or cold can affect hose life and fluid compatibility |
| Fluid compatibility | Compatibility with the hydraulic fluid, including any additives | An unsuitable tube compound may deteriorate or leak |
| Minimum bend radius | Manufacturer’s value for the selected size | Over-bending can stress reinforcement and restrict flow |
| Fittings and assembly | End type, thread, material, and crimping requirements | Correct hose selection alone does not ensure a compatible assembly |
As a general reference, manufacturers commonly offer 2SN hoses in nominal bores from about DN 6 to DN 51. A temperature range often seen for suitable hydraulic oils is approximately -40 °C to +100 °C, but the allowable range depends on the hose and fluid. Neither figure replaces the product-specific datasheet, and pressure ratings must be checked for the actual bore rather than inferred from the construction label.
Applications and Suitability
2SN hoses are used in hydraulic circuits where a flexible connection is needed to carry pressurized fluid. Potential applications include construction and agricultural machinery, industrial equipment, material-handling systems, and hydraulic power units. Suitability depends on the machine’s design, operating conditions, and the hose assembly’s pressure and fluid requirements.

Matching the Hose to the Operating Environment
For equipment exposed to movement or vibration, assess the route carefully and allow enough length for movement without pulling on the connections. In installations with likely abrasion, check whether the cover is suitable or whether additional protection is required. For outdoor or high-temperature service, verify environmental and temperature limits in writing with the supplier.
Where the system experiences pressure surges, do not size the hose using only the normal operating pressure. Ask the equipment designer or supplier to confirm the applicable pressure requirements and safety factors for the system. If the hose will carry a fluid other than a commonly used hydraulic oil, provide the exact fluid name and operating temperature for a compatibility review.
How to Select the Right DIN EN 853 2SN Hose
- Confirm the specification. Check whether the equipment documentation explicitly requires EN 853 2SN or allows an equivalent. Record any project, market, or customer requirements that affect the purchase.
- Identify the size. Confirm nominal bore and the required hose length, including how length is measured for the finished assembly. Compare the hose dimensions with the available installation space and fittings.
- Verify pressure and temperature. Provide the maximum operating pressure, any known pressure surges, and the fluid and ambient temperature ranges. Request ratings for the exact hose size and configuration.
- Check routing and bend radius. Review the path from port to port, movement during operation, and possible contact with hot or abrasive surfaces. Avoid twists and bends tighter than the manufacturer’s stated minimum.
- Specify the complete assembly. Provide fitting types, thread standards, orientation, and any required protective sleeves or identification. Confirm that the hose and fittings are compatible as an assembled product.
- Review documentation before ordering. Compare the supplier’s datasheet and quotation with the equipment requirements. Resolve any differences in dimensions, pressure, temperature, or material before approving production.
Pricing, MOQ, and Lead Time
The purchase price can vary with hose diameter, ordered quantity, assembly configuration, fitting type, and any requested packaging or documentation. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed in the quotation rather than assumed from a general product description. For a useful quote, send the size, quantity, target delivery date, required standard, fluid, operating conditions, and fitting details together.
Common Selection Mistakes
- Choosing by label alone: “2SN” describes construction, not every pressure or temperature requirement for every size.
- Ignoring fluid compatibility: A hose may be unsuitable even if its dimensions and pressure rating appear correct.
- Overlooking assembly details: Incorrect threads, fitting orientation, or crimp specifications can prevent installation or compromise performance.
- Neglecting routing: Tight bends, twisting, and external abrasion may shorten service life or create installation problems.
Supplier Evaluation Checklist
When comparing suppliers, ask for a size-specific datasheet, clear pressure and temperature ratings, and confirmation of the offered construction. Check whether the quotation covers hose only or a complete assembly, and verify fitting details, packaging, order quantity, and delivery terms. If your application has unusual fluid, temperature, or routing conditions, provide those details and request a written suitability response.
