DIN EN 853 2SN hydraulic hose is a high-pressure hose construction with an oil-resistant synthetic rubber tube, two braided layers of high-tensile steel wire, and a protective synthetic rubber cover. Buyers commonly consider it for hydraulic lines on mobile machinery, industrial equipment, and other systems where pressure, fluid compatibility, temperature, and movement requirements match the hose’s rated limits. The exact working pressure depends on the hose size and product specification, so confirm the data sheet rather than selecting by the 2SN designation alone. This guide explains the construction, typical applications, key selection checks, and information to prepare when requesting a quotation.

This guide is intended for hydraulic equipment manufacturers, maintenance teams, distributors, and procurement professionals comparing hose options or preparing a sourcing specification. It can also help buyers identify the information a hose supplier needs to assess a product request. It is not a substitute for the applicable standard, equipment manufacturer’s instructions, or a verified product data sheet. Where system safety depends on a hose assembly, evaluate the complete assembly rather than the hose tube alone.
A typical EN 853 2SN hose has three main layers: an inner tube, two steel-wire braid reinforcement layers, and an outer cover. The inner tube carries the hydraulic fluid, while the braids provide reinforcement against internal pressure. The cover protects the reinforcement from external wear and environmental exposure within the limits stated for the specific product. Construction details and materials should be confirmed with the manufacturer’s specification.
The “2” in 2SN refers to two wire-braid reinforcement layers, while “SN” identifies a compact hose construction in the EN 853 product family. The designation helps buyers identify a construction category, but it is not a complete purchasing specification. Diameter, pressure rating, bend radius, cover properties, and compatible end connections still need to be checked for the selected size and application.
Before ordering, compare the product data with the requirements of the hydraulic circuit. Working pressure and minimum burst pressure are different values: working pressure is the relevant operating limit, while burst pressure is not an allowable continuous operating target. Confirm that the selected hose size is rated for the system’s maximum pressure, including pressure peaks where applicable. Use the product’s declared ratings and the equipment manufacturer’s instructions when making that assessment.
| Specification | What to check | Why it matters |
|---|---|---|
| Hose size | Inside diameter, outside diameter, and connection size | Affects flow, fit, and assembly compatibility |
| Pressure | Rated working pressure for the specific size and product | Must suit system pressure and operating conditions |
| Temperature | Published range for the hose, fluid, and environment | Exceeding the stated range may affect service suitability |
| Bend radius | Minimum permitted radius during installation and operation | Helps prevent kinking or excessive hose stress |
| Fluid compatibility | Tube compatibility with the actual hydraulic medium | Not every tube material suits every fluid |
Many 2SN products are specified for operating temperatures up to 100°C, but the exact range and any fluid-specific limits depend on the product. Treat 100°C as a data point to verify, not a universal guarantee for every hose, fluid, or assembly. Environmental exposure, impulse conditions, and installation can also affect product suitability. Request the current technical sheet for the proposed item.
The tube and cover are generally synthetic rubber compounds selected for their intended service, with steel wire braid reinforcement between them. Available cover properties may differ by manufacturer and product range; options can include resistance characteristics intended for particular external conditions. Do not assume a standard 2SN cover is suitable for every exposure, such as severe abrasion, outdoor weathering, or contact with chemicals. Describe the environment to the supplier so the proposed specification can be checked.
EN 853 2SN hoses are used in hydraulic circuits where the selected size and rating fit the equipment requirements. Possible applications include hydraulic lines on construction and agricultural machinery, material-handling equipment, and stationary industrial systems. These are application categories, not a guarantee that a particular hose is appropriate for every machine in that category. Confirm the machine manufacturer’s requirements and the hose’s rated performance before substitution.

Match the hose to the system rather than choosing by application name alone. Check the fluid, maximum operating pressure, temperature range, required flow, movement, vibration, routing, and external exposure. An undersized inside diameter can affect flow and system performance, while an unsuitable bend or routing can put stress on the hose and fittings. A qualified engineer should review the selection when operating conditions are uncertain or safety-critical.
Document the working fluid, normal and maximum pressure, temperature range, and expected duty cycle. Include pressure fluctuations or frequent movement if they are relevant to the circuit. If the hose operates near a heat source or may contact abrasive surfaces, record that exposure as well. Clear operating information helps a supplier assess the right product more effectively than a size-only request.
Identify the required nominal size and verify the connection dimensions at both ends. Measure the installed path, allowing for movement and service access, and compare the proposed route with the published minimum bend radius. Avoid twisting the hose during installation and do not use the hose to compensate for misaligned ports. Check that clamps or protective sleeves, if required, will not create damaging pinch points.
Provide fitting type, end configuration, thread standard, orientation, and finished assembly length. State whether you require hose only or a crimped assembly, and identify any protective accessories or marking requirements. A fitting that appears similar may use a different thread or sealing method, so verify the connection rather than relying on visual similarity. Confirm that the hose and fittings are intended to work together as an assembly.
Pricing for 2SN hose and assemblies can depend on size, length, fittings, material specification, order quantity, packaging, and inspection or documentation requirements. Minimum order quantities and lead times are supplier- and order-specific, so they should be confirmed in the quotation rather than assumed from the hose designation. For repeat purchasing, share expected order volumes and delivery schedule to support a practical supply discussion. Request that the quotation identify the exact product, size, rating, and assembly scope.
At Hengshui Xinchi Hose Manufacturing Co., Ltd., we support B2B inquiries for hydraulic rubber hose products, including requests involving DIN EN 853 2SN specifications. To help us review a requirement, send the hose size, operating pressure, fluid, temperature, length, fitting details, quantity, and destination market. We can use those details to discuss the requested configuration and identify what should be confirmed against the relevant product data. Please include drawings or existing part references where available, but verify all dimensions and ratings before placing an order.
DIN EN 853 2SN is a two-wire-braid hydraulic hose construction that may suit high-pressure hydraulic applications when its specific ratings and materials match the system. The 2SN designation alone is not enough to confirm suitability: verify the pressure rating by size, temperature limits, fluid compatibility, bend radius, and connection details. As a next step, prepare the operating conditions and assembly requirements, then request a product data sheet and itemized quotation from your supplier. This approach gives your engineering and purchasing teams a clearer basis for comparing options and confirming the order.
