SAE 100 R4

1. Strictly Complies with SAE J517 Standard

Our SAE 100 R4 hydraulic hose is fully manufactured to SAE J517 specifications, ensuring stable performance and wide compatibility. With excellent anti-vacuum performance, it can withstand up to 28 inHg vacuum without collapse, making it the ideal hydraulic suction and return hose for pump inlet and low-pressure circuits.

2. Excellent Oil & Fluid Resistance

Adopting high-quality NBR inner tube, this oil resistant hydraulic hose delivers strong resistance to petroleum-based hydraulic oil, lubricating oil and water-glycol fluids. It works steadily in a temperature range from -40°C to 100°C, effectively reducing swelling and aging for longer service life.

3. High Strength & Safety Performance

Reinforced with textile braid and helical steel wire, our SAE 100 R4 hydraulic hose supports working pressure from 0.8 to 3.4 MPa. The burst pressure reaches over 4 times the working pressure, providing high safety margin and reliable performance in heavy-duty industrial conditions.

4. Superior Weather & Aging Resistance

The outer rubber layer is specially formulated for ozone resistance, weather resistance and wear resistance. It maintains good flexibility and integrity even in long-term outdoor use, suitable for construction machinery, agricultural equipment and various mobile hydraulic systems.

5. Customization & Factory Direct Supply
