EN 857 1SC Hydraulic Hose

Product Overview

EN 857 1SC hydraulic hose represents the ideal solution for compact installation spaces requiring high pressure performance. This wire braided hydraulic hose follows the EN 857 1SC standard, which maintains the same robust construction as EN 853 1SN but with a critical advantage—significantly smaller outside diameters. For equipment manufacturers and maintenance engineers facing narrow piping layouts, this compact design eliminates installation constraints while delivering reliable high pressure capability.

The hose structure consists of three precision-engineered layers: an inner tube of black oil-resistant synthetic rubber, a single high tensile steel wire braid reinforcement, and an outer cover of weather and abrasion-resistant synthetic rubber with cloth impression finish. Operating effectively from -40°C to +100°C, this rubber hose handles the most demanding hydraulic applications.

Key performance include working pressures up to 22.5 MPa (3260 Psi) for smaller sizes, minimum burst pressure reaching 90 MPa (13050 Psi), and exceptional flexibility with minimum bending radii as low as 75 mm. The compact design reduces weight by up to 20% compared to standard hoses, making it ideal for mobile equipment.

This high pressure hose solves the core industry pain point of installation space limitations without compromising safety or performance. Whether you need to retrofit existing machinery or design new compact equipment, EN 857 1SC provides the solution. As a leading China manufacturer, we ensure every hose meets strict quality standards with full traceability and certification.

Product Advantages

Compact Design Leadership: The reduced outside diameter profile—up to 15% smaller than equivalent EN 853 1SN hoses—enables installation in previously impossible spaces. This space-saving advantage proves invaluable for robotic systems, compact construction equipment, and machinery with dense hydraulic packaging.

Superior Pressure Performance: Despite the compact dimensions, the high tensile steel wire reinforcement delivers exceptional working pressure ratings. The 4:1 safety factor (minimum burst pressure equals four times working pressure) exceeds industry requirements, providing operators confidence in high stress applications.

Enhanced Durability Package: The oil-resistant synthetic rubber tube resists degradation from hydraulic fluids, while the abrasion and weather-resistant cover protects against external damage. Ozone, UV, and aging resistance ensure long service life even in outdoor applications across diverse climates.

Application Versatility: From construction equipment to agricultural machinery, this wire braided hose adapts to numerous environments. The -40°C low-temperature flexibility ensures reliable cold starts in northern regions, while the +100°C continuous operating temperature handles high heat applications.

Applicable Users: Ideal for hydraulic system designers, maintenance professionals, and equipment manufacturers across construction, mining, agriculture, material handling, and industrial manufacturing sectors.

Detailed Technical Specifications Table

Structure and Materials

Inner Tube: Manufactured from high-quality black oil-resistant synthetic rubber, the tube provides excellent compatibility with mineral oils, water-oil emulsions, and biodegradable hydraulic fluids. The smooth bore ensures minimal flow resistance and prevents particle accumulation, extending system component life. Our laboratory testing confirms superior swelling resistance after 1000 hours of immersion at 100°C.

Reinforcement Layer: A single layer of high tensile braided steel wire forms the pressure-bearing component. The precise braiding angle—optimized at 54.7 degrees—balances radial and axial forces during pressure cycles. Each wire undergoes tensile testing before braiding, ensuring consistent reinforcement quality. This construction enables the hose to exceed EN 857 1SC standard requirements for impulse resistance.

Outer Cover: The synthetic rubber cover incorporates specialized compounds for abrasion resistance, weather protection, and ozone resistance. The cloth impression finish provides additional grip for hose assembly handling and identifies the hose as EN 857 1SC specification. Cover materials resist industrial fluids, UV exposure, and mechanical damage during installation.

Application Industries

Construction Equipment: Excavators, loaders, bulldozers, and compactors utilize this hose for boom circuits, implement controls, and pilot systems where space constraints require compact routing.

Agricultural Machinery: Tractors, harvesters, sprayers, and balers benefit from the hose’s flexibility for articulation points and tight engine compartment installations.

Material Handling: Forklifts, aerial work platforms, and conveyor systems require the compact dimensions for mast assemblies and tight radius routing.

Industrial Manufacturing: Injection molding machines, presses, and automation equipment integrate this wire braided hose for hydraulic power units and actuator connections.

Mining Equipment: Underground machinery and surface mining vehicles demand the durability and compact routing capabilities for space-limited compartments.

Transportation: Truck-mounted cranes, refuse vehicles, and mobile hydraulics benefit from weight savings and installation flexibility.

Precise Selection Professional Guide

Hose Assembly Integration: EN 857 1SC hydraulic hose performs optimally when paired with correctly selected crimped fittings. Our technical team recommends using fittings designed specifically for compact hose dimensions to maintain proper compression and fitting retention. The hose assembly process requires precision skiving depth control to prevent wire reinforcement damage during crimping.

Comparison with EN 853 1SN: While both share similar construction, EN 857 1SC offers 15-20% reduced outside diameter for the same pressure rating. This makes it ideal for multi-line installations where space constraints prevent using standard hoses. The weight reduction per meter ranges from 10-25% depending on size, contributing to overall equipment efficiency.

Fitting Compatibility: This hose accepts standard crimped fittings, reusable fittings, and adapters compatible with 1SN specifications. For high-vibration applications, we recommend spiral hose protection using guards or protective sleeves to extend service life. Flanges and adapters should match the working pressure rating of the hose assembly.

Installation Best Practices: Maintain minimum bending radius recommendations to prevent kinking and premature failure. Use protective sleeves when routing near heat sources or abrasive surfaces. Our field testing demonstrates that proper clamping every 300-500 mm reduces system stress and extends hose life by up to 40%.

Installation, Operation, and Maintenance Guide

Pre-Installation Inspection: Examine hoses for shipping damage, clean ends before fitting installation, and verify correct size and pressure rating match system requirements.

Fitting Attachment: Use manufacturer-recommended crimp specifications and crimping equipment. Verify crimp diameter with calibrated gauges and perform pull-off tests on sample assemblies.

Routing Guidelines: Avoid twisting during installation—mark hose centerline before bending. Support hoses properly with clamps every 300-500 mm depending on application. Maintain clearance from moving components and heat sources.

Operating Parameters: Do not exceed working pressure ratings. Monitor system temperature to remain within -40°C to +100°C range. Replace hoses showing cover damage, kinking, or leakage.

Maintenance Schedule: Inspect quarterly for external damage, fitting corrosion, or system leaks. Replace hoses after five years of service or earlier if operating in severe conditions. Document installation dates and service history for predictive maintenance programs.
