SAE 100 R4 Hydraulic Hose

 SAE 100R4 Suction and Return Hose

SAE 100 R4 is a standard specification for low-pressure return lines used in hydraulic systems to suction 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.

SAE 100 R4 Structure:

Tube: High quality black oil resistant synthetic rubber, making this hose widely used for oil transportation.

Reinforcement: High tensile textile cords with flexible steel helix wire

Cover: High quality synthetic rubber that is wear resistant, corrosion resistant, weather resistant, and ozone resistant.

Feature

ID Range: 3/4″ to 4″ ID

Working pressure：58psi to 305psi

Safety factor: 4:1

Temperature Range: -40℃ to 100 ℃.(-40°F to +212°F)

Applicable Standards: Meets or exceeds requirements of SAE 100R4

Application:

SAE 100 R4 tubing is commonly used in oil suction and return Low pressure and vacuum petroleum base fluid 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.
