DIN EN 857 1SC is a compact hydraulic hose construction with one high-tensile steel-wire braid reinforcement. Buyers typically consider it when a hydraulic line needs a smaller outside diameter or tighter routing than some conventional wire-braid hose designs can provide. Common product ranges cover nominal bore sizes from approximately 5 mm to 25 mm, and many product data sheets state an operating temperature range of -40°C to +100°C for compatible fluids. These are general reference points, not a substitute for the pressure, temperature, and fluid-compatibility ratings of the exact hose and assembly you intend to purchase.
This guide explains the construction, specification details, size considerations, and application checks that help B2B buyers evaluate 1SC hose. At Hengshui Xinchi Hose Manufacturing Co., Ltd., we recommend confirming the complete operating conditions and fitting requirements before requesting a quotation. That approach helps buyers compare products on a like-for-like basis rather than relying on the 1SC designation alone.
This guide is intended for hydraulic equipment manufacturers, distributors, maintenance teams, and procurement professionals evaluating compact wire-braid hose. It is useful when you need to identify a hose by standard designation, compare bore sizes, or prepare a specification for supplier quotations. It can also help when replacing an existing hose, although the old hose’s marking and dimensions should be checked against the machine requirements before ordering.
It is not a substitute for an engineering review of a hydraulic circuit. Where pressure pulses, high temperatures, unusual fluids, or safety-critical functions are involved, confirm the selection with the equipment designer or a qualified hydraulic specialist. A hose that fits physically may still be unsuitable for the system’s pressure, fluid, or routing conditions.
In the 1SC designation, “1” identifies a single-wire-braid reinforcement construction, while “SC” refers to the compact hose type under the EN 857 family. A typical hose has an oil-resistant synthetic-rubber tube, one braided steel-wire reinforcement layer, and a synthetic-rubber cover designed to resist external exposure such as abrasion and weathering. The exact compounds and cover performance depend on the manufacturer’s product specification.
The inner tube carries the hydraulic fluid, the reinforcement supports pressure containment, and the outer cover protects the hose from its working environment. The braid construction is one part of the hose’s performance; the end fittings, assembly method, installation, and operating conditions also affect service suitability. For this reason, buyers should specify the complete hose assembly when the hose will be supplied with fitted connectors.
EN 857 1SC has one wire-braid reinforcement layer, whereas EN 857 2SC uses two. A two-braid hose is not automatically the right choice for every application, just as a compact 1SC hose should not be selected solely because it is easier to route. Compare the pressure requirements, dimensions, bend radius, and applicable product data for each candidate.
Some buyers also compare 1SC with SAE-designated hoses. Similar appearance or overlapping applications do not establish that products are interchangeable. Before substituting one designation for another, check the relevant standards, the manufacturer’s ratings, and any equipment or customer requirements.
Use the manufacturer’s technical data sheet to verify the hose’s working pressure, minimum burst pressure where specified, minimum bend radius, outside diameter, and mass per unit length. Working pressure generally varies with hose size and construction, so there is no single pressure value that applies to every 1SC hose. Do not estimate a hose’s pressure capacity from its appearance or from a rating published for another diameter.
Many 1SC product ranges list nominal bore sizes in the approximate DN 5–DN 25 range. The exact size series, inside-diameter tolerances, and available lengths can differ by manufacturer, so treat this as an orientation point rather than a guaranteed range. Match the hose bore to the equipment specification and verify the fitting size and connection type separately.

| Specification item | What buyers should check |
|---|---|
| Hose designation | Confirm EN 857 1SC and any required edition or customer specification. |
| Nominal bore | Match the required DN or inside diameter; confirm the actual product dimensions. |
| Working pressure | Check the rated pressure for the selected size and the intended service conditions. |
| Temperature | Verify the hose rating for the fluid, ambient temperature, and operating cycle. |
| Routing and fittings | Check bend radius, assembly length, end connections, and movement during operation. |
A commonly published temperature range for compatible hydraulic fluids is -40°C to +100°C, but the allowable range depends on the specific hose compound and fluid. Water-based fluids, certain chemical mixtures, and other non-standard media may require lower limits or a different tube material. Confirm compatibility with the hose supplier and consult the applicable product data before use.
Temperature is not only the temperature of the surrounding air. The fluid can heat during operation, and intermittent peaks may differ from the system’s normal running temperature. Record both the expected continuous conditions and any known short-term extremes when requesting a recommendation.
Compact single-braid hoses may be considered for hydraulic lines on mobile equipment, industrial machinery, and other systems where space-efficient routing is valuable. Potential uses include pressure lines, return lines, and control circuits, provided the selected hose’s pressure and fluid ratings suit that circuit. The application name alone does not establish suitability; the system’s actual duty conditions must guide the selection.
Start by identifying the circuit function and maximum operating pressure, including pressure peaks if known. Then assess the fluid type, temperature range, movement, vibration, and exposure to abrasion or weather. Finally, confirm whether the available space allows the manufacturer’s specified bend radius and whether the fittings can be installed without twisting or side-loading the hose.
For replacements, use the machine documentation or hose markings as a starting point, not as the only source of truth. Check whether the original line was modified and whether its fittings, length, or routing differ from the equipment specification. If information is missing, share photographs and measurements with the supplier, while having a qualified person verify the final selection.
The price of a 1SC hose depends on factors such as bore size, order quantity, hose length, compound and cover requirements, and whether the product is supplied in bulk length or as a fitted assembly. Special packaging, labeling, and documentation can also affect a quotation. Buyers should request pricing against a clear specification so offers can be compared consistently.
Minimum order quantities and lead times are supplier- and order-specific; they should be confirmed for the requested size and configuration. Availability may differ between standard hose and custom assemblies, and production or shipping schedules can change. For project planning, ask the supplier to state the quoted quantity basis, production lead time, shipping terms, and any sample or pre-production approval steps.
When evaluating a supplier, confirm that it can identify the product as EN 857 1SC and provide a datasheet for the size you need. Check that the document includes the dimensions and operating ratings relevant to your application, and ask how the supplier identifies products and batches if traceability is part of your purchasing requirement. Avoid treating a general product description as proof of a specific certification or test unless the supplier provides applicable documentation.
DIN EN 857 1SC is a compact hydraulic hose construction using one steel-wire braid, commonly considered where routing space is limited. Approximate size availability from DN 5 to DN 25 and a commonly stated temperature range of -40°C to +100°C can help frame an initial search, but neither replaces the exact manufacturer’s ratings. Pressure capacity, bend radius, fluid compatibility, and fitting suitability must be confirmed for the selected size and operating conditions.
To move from evaluation to purchasing, prepare the required bore, working pressure, fluid, temperature range, hose length, routing details, and end connections. Hengshui Xinchi Hose Manufacturing Co., Ltd. can review these details and discuss suitable DIN EN 857 1SC hose options for your sourcing requirements. Send your specification or inquiry details to request product information and a quotation, and confirm all technical ratings before placing an order.
