DIN EN853 2SN Hydraulic Hoses: Specifications, Applications, and Selection Guide
DIN EN853 2SN is a high-pressure hydraulic hose type made with a synthetic-rubber inner tube, two braided steel-wire reinforcement layers, and a protective rubber cover. It is commonly selected for hydraulic lines on mobile and industrial equipment where flexibility and resistance to pressure are required. To choose the right hose, match its size, working pressure, temperature range, fluid compatibility, and routing conditions to the equipment requirements. Exact pressure ratings and minimum bend radii vary by hose size and manufacturer, so confirm them against the product datasheet before ordering.

Key Takeaways
- 2SN identifies a hose construction with two steel-wire braid reinforcement layers; it does not specify one universal pressure rating.
- Confirm the hose’s size-specific working pressure, minimum bend radius, temperature limits, and fluid compatibility for the intended application.
- Share complete operating and assembly details with your supplier to reduce the risk of incorrect selection or fit.
Who This Guide Is For
This guide is for procurement teams, hydraulic-system designers, equipment manufacturers, and distributors sourcing DIN EN853 2SN hoses. It is also useful when replacing a hose on existing machinery and checking whether a proposed alternative matches the original requirements. The information supports product evaluation, but it does not replace the machine manufacturer’s instructions or a qualified engineering review. When safety or system performance depends on the hose assembly, verify the complete assembly—not just the hose tube—before use.
What Is a DIN EN853 2SN Hydraulic Hose?
DIN EN853 2SN refers to a type of wire-braided hydraulic hose covered by the EN 853 hose standard. The “2” indicates two reinforcement braids, while “SN” is used to identify this construction type within the standard. The hose is designed to convey hydraulic fluid under pressure, with its reinforcement carrying the pressure load and its rubber layers providing a fluid-contact surface and external protection. The standard designation helps buyers identify a construction category, but product dimensions and performance ratings still need to be checked for the selected size.
Typical Construction and Materials
A typical 2SN hose has an oil-resistant synthetic-rubber inner tube, two high-tensile steel-wire braid layers, and a synthetic-rubber outer cover. The inner tube must be compatible with the specified hydraulic fluid, while the reinforcement supports operation within the hose’s rated pressure limits. The cover protects against external conditions such as abrasion and weather exposure, subject to the manufacturer’s stated capabilities. Material formulations can differ, so request the technical datasheet when fluid type or environmental exposure is important.
Specifications Buyers Should Check
There is no single working-pressure figure that applies to every 2SN hose. Pressure capacity changes with nominal bore and product design, and the minimum bend radius is also size-specific. For pressure-unit conversions, 1 MPa equals 10 bar; use the units consistently when comparing a machine requirement with a supplier’s datasheet. Ask for the working pressure, any stated pressure-test information, and the applicable safety requirements rather than relying on a general description of “high pressure.”
| Specification | What to confirm | Why it matters |
|---|---|---|
| Nominal size and inside diameter | Required hose size and connection dimensions | A mismatch can affect flow, fit, and system performance. |
| Working pressure | Size-specific rating and system operating conditions | The hose must be suitable for the pressure demands of the application. |
| Temperature range | Fluid and ambient temperatures, including operating extremes | Temperature can affect material suitability and service life. |
| Minimum bend radius | Published minimum for the selected size | Over-bending can damage the hose or restrict its installation. |
| Fluid and cover compatibility | Hydraulic fluid, external exposure, and abrasion conditions | Compatibility depends on the actual materials and operating environment. |
| Assembly details | Fittings, end connections, length, and crimping requirements | The assembly must match the equipment and installation method. |
Applications and Hose Matching
DIN EN853 2SN hoses are used in hydraulic circuits on equipment such as construction machinery, agricultural machines, material-handling equipment, and industrial systems. Suitability depends on the system design and the hose’s actual ratings, rather than the application name alone. A machine may have multiple lines with different pressure, temperature, movement, and routing requirements. Identify the conditions for each line before specifying a replacement or sourcing a production quantity.

Match the Hose to the Operating Conditions
Start with the equipment documentation or the markings on the existing hose, then confirm the required inside diameter, length, and fitting type. Record the maximum operating pressure and temperature, the hydraulic fluid, and whether the hose is exposed to abrasion, weather, or repeated movement. Check the route for tight bends, contact with nearby components, and potential twisting during installation. For example, specifying a 25 mm inside diameter is only useful if that size also matches the system’s flow and connection requirements.
A Practical Selection Framework
- Define the system requirements. Record operating pressure, fluid type, temperature range, hose size, and connection details using equipment documentation where available.
- Check the product datasheet. Compare size-specific working pressure, minimum bend radius, dimensions, and material compatibility with the application.
- Review the hose route. Allow for movement and installation clearance, and avoid routing that forces the hose below its published bend radius or introduces twist.
- Specify the assembly. Confirm fitting style, orientation, finished length, and any applicable assembly requirements with the supplier.
- Verify before installation. Check product identification and assembly details against the purchase specification and machine requirements.
Pricing, MOQ, and Lead-Time Considerations
Pricing for 2SN hose can depend on size, required quantity, hose length, fitting configuration, and any requested packaging or documentation. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed during quotation rather than assumed from the hose designation. Complete specifications make it easier to compare quotations on an equivalent basis. If the hose is part of an assembled product, ask whether the quotation covers hose only or finished assemblies with fittings.
Common Selection Mistakes
- Choosing by designation alone: “2SN” identifies the construction type, not the complete pressure and dimensional specification.
- Using an unverified pressure figure: Compare the equipment requirement with the rating for the exact hose size and product.
- Ignoring routing: A hose that meets pressure requirements may still be unsuitable if the installed route exceeds its bend or movement limits.
- Overlooking fluid or environment: Confirm compatibility with both the hydraulic medium and external exposure conditions.
- Ordering without assembly details: Incorrect fittings, orientation, or finished length can prevent a hose assembly from fitting the equipment.
Evaluating a Supplier
Before placing a B2B order, ask the supplier for a current datasheet that identifies the offered hose size, construction, pressure rating, temperature limits, and minimum bend radius. Confirm how the supplier identifies products and batches, what inspection or documentation is available, and whether the quotation covers the required hose or complete assembly. For repeat purchasing, align the product description and revision details in your internal specification so future orders can be checked consistently. These questions help buyers assess technical fit without relying on broad claims that are not supported by product documentation.

Where a requirement is uncertain, provide the machine specification or existing hose markings so our team can help identify the details that need verification.
Conclusion: What to Do Next
DIN EN853 2SN is a two-wire-braid hydraulic hose construction used in a range of hydraulic applications, but the designation alone is not enough to select a product safely or accurately. Confirm the exact size, working pressure, temperature limits, fluid compatibility, bend radius, and assembly details against the equipment requirements and supplier datasheet. For your next step, prepare those specifications and request a quotation that clearly states whether it covers hose only or finished assemblies. Contact XINCHI with your application and purchasing requirements to discuss product fit, available documentation, and supply options.
