Our steel wire braided hydraulic hose with constant pressure is engineered to meet the rigorous demands of modern hydraulic systems, fully compliant with SAE100 R17 and EN857 standards at a consistent 22.5Mpa working pressure. This premium constant pressure hydraulic hose features a robust three-layer construction: an inner tube made from high-quality oil-resistant synthetic rubber, one or two layers of high-tensile steel wire braid reinforcement, and a durable oil and weather-resistant rubber outer cover. Designed for reliable performance in challenging industrial environments, our SAE100 R17 hydraulic hose delivers exceptional pressure resistance, flexibility, and long service life, making it the preferred choice for industrial equipment manufacturers and maintenance professionals worldwide.
Unlike conventional hydraulic hoses that experience pressure drops with increasing diameter, our EN857 hydraulic hose maintains a uniform 22.5Mpa working pressure across the entire size range from 6.3mm to 25mm nominal diameter. This consistent performance simplifies system design and ensures reliable operation in complex hydraulic circuits.
The high-tensile steel wire braided reinforcement provides exceptional burst resistance (up to 90Mpa) while maintaining excellent flexibility. The oil-resistant inner tube prevents degradation from common hydraulic fluids, while the weather-resistant outer cover protects against UV radiation, ozone, and abrasion, extending service life in outdoor applications.
Our 22.5Mpa hydraulic hose operates reliably in temperatures ranging from -40℃ to +120℃ for standard hydraulic fluids. For water-based media, it can handle temperatures from 0℃ to 70℃, making it suitable for diverse operating conditions across multiple industries.
We offer comprehensive customization services to meet your specific requirements, including custom lengths, special end fittings, and custom color coding for easy identification in complex systems.

Our industrial hydraulic hose is ideal for conveying a wide range of hydraulic fluids including mineral oils, glycols, lubricants, emulsions, and hydrocarbons. It is widely used in:
Construction machinery and equipment
Agricultural machinery and tractors
Material handling equipment (forklifts, cranes)
Industrial manufacturing machinery
Mining equipment
Marine hydraulic systems
Automotive manufacturing lines
Note: This hose is not suitable for conveying phosphate ester-based fluids.
Constant pressure hoses maintain the same working pressure rating across all sizes, whereas standard hoses typically have lower pressure ratings for larger diameters. This makes constant pressure hoses ideal for systems where consistent performance is critical.
Yes, our hydraulic fluid transfer hose is compatible with water-based emulsions and glycol solutions. However, the maximum operating temperature for water-based media is 70℃.
We offer flexible order quantities to accommodate both small maintenance projects and large-scale production requirements. Contact our sales team for detailed pricing information.
Yes, we offer complete custom assembly services including cutting to length, crimping end fittings, and pressure testing to ensure your hoses are ready for immediate installation.
