Hydraulic hose material selection affects oil resistance, pressure capability, flexibility, abrasion life and safety. A hose is not one material; it is a system of tube compound, reinforcement, cover compound and metal fittings.
Main Hose Materials
| Material | Where used | Main function |
| NBR or oil-resistant synthetic rubber | Inner tube | Resists mineral hydraulic oil and helps maintain flexibility |
| High-tensile steel wire | Reinforcement | Carries hydraulic pressure and impulse load |
| Synthetic rubber cover | Outer layer | Protects against abrasion, weather, ozone and oil splash |
| Textile reinforcement | Low and medium pressure hose | Provides flexibility and lower weight |
| Thermoplastic tube/cover | Compact specialty hose | Lightweight, clean routing and some non-conductive options |
Material Comparison by Application
| Aplikasi | Preferred material feature | Reason |
| Mining and quarry | Strong cover compound and steel wire reinforcement | Abrasion, rocks and severe vibration |
| Pertanian | Flexible rubber and common fitting compatibility | Field repair and seasonal equipment movement |
| Kelautan | Oil and corrosion-aware fitting selection | Salt, humidity and onboard maintenance |
| Factory hydraulic systems | Clean smooth cover and stable tube material | Leak inspection and repeatable maintenance |
| Chemical or special media | Specific tube compatibility | Hydraulic oil hose may not suit chemicals |
Fittings and Ferrules Matter Too
Even the best hose can fail if fittings are wrong. Common hydraulic fitting materials include carbon steel with plating and stainless steel for corrosion-sensitive environments. Thread standard selection – BSP, NPTF, JIC, DIN Metric, ORFS or SAE flange – must match the equipment port.
Cover Materials: Smooth vs Wrapped
Smooth cover hoses are often selected for OEM production, clean factories and easy marking. Wrapped cover hoses are common in field repair, construction, mining and plantation equipment. Abrasion resistance depends on the cover compound and construction, not surface texture alone.
FAQ
Is rubber hydraulic hose compatible with all fluids?
No. Confirm compatibility with mineral oil, water-glycol, biodegradable fluids, fuel, chemical media or high-temperature oil before ordering.
Why do outdoor hoses crack?
Heat, ozone, sunlight, oil contamination and bending stress can age the cover. Correct compound and routing reduce this risk.
