Hydraulic Oil Hose Resistant To Hydraulic Fluid Aging High Impulse Resistance
Product Advantages
Engineered for hazardous marine environments, our electrically conductive hydraulic hose prevents static buildup, reducing fire risks in fuel transfer and hydraulic systems. The carbon-black-infused rubber compound ensures <1MΩ/m resistance (ISO 8031 compliant).
Key Benefits
♦ Explosion-proof design – Essential for tankers, oil rigs, and ATEX-regulated zones.
♦ High-pressure rating (35 MPa) – Safe for heavy-duty hydraulic applications.
♦ Flame-retardant cover – Meets ISO 3795 fire resistance standards.
♦ Compatible with HFA/HFB fluids – Resists degradation from water-oil emulsions.

Why Choose Hongruntong Marine?
♦ Structural Design
Two-layer steel wire braid (2SN) with a low-friction polyurethane inner tube and a highly flexible synthetic rubber cover. Bend radius 30% smaller than standard hoses, enabling tight-space routing.
♦ Performance
Dynamic pressure 25 MPa, static pressure 40 MPa. Bend cycle life >1,000,000 (SAE J343). Temperature range: -54°C to +121°C (peak 150°C).
♦ Fluid Compatibility
Resistant to phosphate ester fluids (e.g., Skydrol LD-4) and aviation hydraulic oils. Chemically inert per ASTM D471.
♦ Environmental Suitability
Salt spray- and humidity-resistant for aerospace, marine, and mobile hydraulics. Complies with SAE 100R5, MSHA/OSHA standards.
FAQ
1. Which fluids are compatible with hydraulic hoses?
They are compatible with mineral oil, synthetic esters, polyglycols, HFD-R, HFD-S, HFD-U, and biodegradable fluids.
2. What is the difference between 1-wire and 2-wire hydraulic hoses?
1-wire hoses are suitable for lower pressure systems; 2-wire hoses offer higher pressure capacity and durability.
3. What does SAE 100R1 or R2 mean?
These are SAE standards that define hose construction, performance, and pressure ratings for hydraulic hoses.
4. Can hydraulic hoses be used with water or air?
Some types are compatible with water-glycol fluids; however, they are not typically designed for air unless specified.
