High Performance SAE100 R4

GR4 (SAE 100 R4) Hydraulic Hose

GR4 (SAE 100 R4)

SAE 100 R4 is a standard specification for low-pressure return lines used in hydraulic systems to absorb and return petroleum and water-based fluids. The hose is made of oil-resistant rubber, capable of withstanding high temperature and pressure environments while maintaining flexibility and tensile strength.

SAE 100 R4 hoses are commonly used in industrial and automotive applications and are reliable for low-pressure oil lines.

 

GR4 (SAE 100 R4) Structure:

1. Tube: Oil-resistant synthetic rubber

2. Reinforcement: 1 ply or plies of woven or braided

textile fibers with a suitable spiral of body steel wire

3. Cover: Oil and weather-resistant rubber

4. Application: Low pressure and vacuum petroleum base fluid

5. Safety factor:4:1

6. Temperature Range:-40℃ to 100 ℃

Application:

SAE 100 R4 tubing is commonly used in oil suction and return applications such as:

Hydraulic system: used for oil suction and return pipelines in hydraulic transmission systems, including industrial machinery, construction machinery, agricultural machinery, etc.; such as rolling mills, cranes, injection molding machines, etc. steel mills in industrial machinery, and tractors in agricultural machinery, Combine harvesters, irrigation equipment, etc., all use SAE 100 R4 tubing in hydraulic systems.

Ships: used for oil suction and return pipelines, including main engines, auxiliary engines, pumping stations, etc.;

Construction machinery: excavators, loaders, bulldozers, etc., such as hydraulic oil tanks, steering gears, hydraulic pumps, and other parts of excavators;

Automobiles: automobile engines, transmissions, steering gears, etc.;

Aircraft: aircraft engines, hydraulic systems, fuel systems, etc.

Applicable Standards: SAE 100 R4
