Textile Overbraid SAE R5 Hydraulic Hose

(Textile Overbraid Hydraulic Hose SAE R5)
Lightweight First Choice | Extremely Flexible | Medium and High Voltage Energy Saving Solution

Inner Layer: 0.5mm NBR Rubber (Oil Resistance Grade ASTM D471 Class B)
Reinforcement Layer:
Layer 1: 1500D Polyester 54° Braid
Layer 2: 2000D Aramid 45° Cross Braid
Outer Layer: Green/Black Polyurethane (Optional UV Protection Coating)

Structure: Synthetic Rubber Inner Layer + 2 Layers of High Strength Polyester Braid + Wear-Resistant Outer Layer
Working Pressure: 5-25MPa (Burst Pressure ≥ 4 Times Working Pressure)
Pulse Life: ≥300,000 Times @ ±10% Working Pressure (SAE J517 Standard)
Bending Radius: 4×D (40% Smaller Than the Same Grade Steel Wire Braided Hose)
Temperature Range: -40°C ~ +100°C (Short-term Withstand +120°C)
Certification Standard: SAE J517 R5｜ISO 1436 TYPE 1AT｜DIN 20022

Advantages
1. The fiber braided layer is 60% lighter than steel wire, reducing the energy consumption of mobile equipment (actually measured fuel saving of 3.2% for excavator arms).

2. Patented fiber interlaced braiding technology: bending resistance is only 1/5 of that of steel wire hose, suitable for frequently twisted mechanical arms.

3. All-non-metallic structure, perfect for:
▶ Seawater environment (ship deck machinery)
▶ Strong electromagnetic field (MRI equipment hydraulic system)
▶ Chemical corrosion (electroplating workshop)

4. The outer layer resistance value is 10⁴~10⁶Ω (in compliance with ATEX explosion-proof directive), and embedded copper wire is optional (resistance <10³Ω).

5. The price is 25% lower than the same level of 2-layer steel wire hose, and TCO (total cost of ownership) is reduced by 40% (maintenance + energy saving).

Frequently Asked Questions
Q: Will the fiber braided layer age?
A: Passed UV accelerated aging test:
Standard outer layer: 5-year outdoor use strength retention rate > 80%
Optional UV protection: 10-year strength retention rate > 90%

Q: Can it be used for ultra-high pressure (> 25MPa)?
A: It is recommended to upgrade to R17 wire-wound hose, but R5 has the best cost performance within 25MPa.

Q: How to identify inferior fiber hoses?
A: Three-look principle:
Look at the cross section: high-quality fiber is uniformly meshed
Look at the elasticity: no permanent crease after folding
