19mm Industrial Hydraulic Hose High Burst Pressure With High Vibration Resistance
Brief Introduction
Designed for confined marine engine rooms and compact hydraulic systems, our 2SN ultra-flexible hydraulic hose features a two-layer steel wire braid and low-friction polyurethane inner tube, reducing pressure drop and improving flow efficiency. Its 30% smaller bend radius allows easy installation in tight spaces without kinking.

Key Benefits
► Exceptional flexibility – Ideal for moving parts, cranes, and articulated machinery.
► High-pressure performance – Rated for 25 MPa dynamic / 40 MPa static pressure.
► Wide fluid compatibility – Works with phosphate esters (Skydrol), HFD, and water-glycol fluids.
► Marine-grade durability – Resists salt spray, humidity, and extreme temps (-54°C to +121°C).
Why Choose Hongruntong Marine Hydraulic Oil Hoses?
►Structural Design
Carbon-black-embedded rubber compound with a conductive path (resistance <1MΩ/m per ISO 8031) to prevent static buildup.
►Performance
35 MPa working pressure, -40°C to +100°C range. Flame-retardant cover (ISO 3795 compliant).
►Fluid Compatibility
Safe with flammable fluids (e.g., HFA, HFB emulsions).
►Environmental Suitability
Mandatory for explosive atmospheres (ATEX 2014/34/EU).
Application
► Irrigation Machinery - Mobile hydraulic solutions for water systems
► Oil Rig Hydraulics - H₂S-resistant hoses for drilling operations
► Mining Truck Braking - Extreme-duty hydraulic brake lines
► Wind Turbine Pitch Control - Precision hydraulic adjustment systems
FAQ
1. Are hydraulic hoses UV and ozone resistant?
Yes, most outer covers are resistant to UV, ozone, and weathering, especially for outdoor or marine use.
2. Can hydraulic hoses be used underground?
Yes, if they are rated with MSHA flame resistance and proper abrasion protection.
3. What are hydraulic hose impulse cycles?
Impulse cycles simulate pressure fluctuations. Quality hoses often exceed 200,000–1,000,000 cycles.
4. What is a non-skive hydraulic hose?
A non-skive hose does not require removal of the outer cover before attaching fittings, simplifying assembly.
