Our Para-aramid hoses yarn with difference colors offers you steel-like strength and heat resistance at a fraction of the weight, with excellent flexibility and fatigue life, yours ideal choose for high-pressure, high-temperature and long-life hoses produce.
Para-aramid is usually used as the reinforcing braid or spiral layer between the inner tube and the outer cover:
- Hydraulic hoses(high pressure, e.g., SAE 100R7/R8)
- Thermoplastic inner tube (PA, TPU)
- Para-aramid braid reinforcement
- Polyurethane outer cover
- Automotive hoses
- Power steering, brake, or turbo hoses (where heat and pressure pulses are severe)
- Aerospace hoses
- Lightweight, nonmetallic reinforcement is vital for fuel and hydraulic systems.
- Industrial hoses
- For chemicals, compressed air, or hot fluids where steel wire would add weight or corrode.
Para-aramid gives the best strength-to-weight ratio while remaining flexible and heat resistant — a sweet spot for hoses that must bend repeatedly and endure high internal pressures.
Comparison with other reinforcements
| Fiber / Material | Tensile strength (GPa) | Density (g/cm³) | Temp limit (°C) | Key pros | Key cons |
| Steel wire | 1.8–2.0 | 7.8 | 250 | Very strong, low creep | Heavy, corrosion, less flexible |
| Polyester (PES) | 0.8–1.0 | 1.38 | 150 | Cheap, flexible | Limited high-temp & strength |
| Nylon (PA66) | 0.9–1.1 | 1.14 | 120 | Tough, cheap | Absorbs moisture, low modulus |
| Para-aramid | 3.0–3.6 | 1.44 | 200–250 | High strength, low weight | More expensive, sensitive to UV & compression |
| Glass fiber | 2.4–3.0 | 2.5 | 500 | Heat resistant | Brittle, poor flex fatigue |
| PBO (Zylon®) | 5.8 | 1.54 | 400 | Extremely strong | Very expensive, UV sensitive |
