SAE 100 R4 Oil Suction and Return Hydraulic Hose
Hydraulic hose SAE 100 R4 is mainly used for oil suction and delivery in hydraulic systems. The inner and outside tube are made of high-quality oil-resistant synthetic rubber. The middle reinforcement layer is one or more layers of textile fibers with high tensile spiral steel wire, making the hoses have more solid structure and longer service life. This ensures that the hose body does not deform under suction or vacuum conditions, ensuring stable flow. It is suitable for a variety of hydraulic fluids at -40℃-100℃, from petroleum-based to water-based, to meet the application needs of different industries.

FAQ about SAE100 R4
What is SAE 100r4?
SAE 100R4 is a hydraulic oil suction hose suitable for suction and delivery of hydraulic oil in hydraulic systems. It has a three-layer structure, the inner tube is smooth and oil-resistant synthetic rubber, the reinforcement layer is high-strength synthetic cord and spiral steel wire, and the outer cover is weather-resistant synthetic rubber. The working temperature is – 40 ℃ to + 100 ℃. The conveying media include mineral oil, polyethylene glycol-based hydraulic oil, hydraulic oil, etc.
What is a hydraulic suction hose?
Hydraulic suction hoses are designed to withstand both suction (negative pressure or vacuum) conditions, drawing hydraulic fluid from a tank or source, and pumping (positive pressure) conditions, delivering fluid to a desired location. They typically incorporate a spiral steel wire reinforcement layer embedded between the inner and outer tubes to prevent the hose from collapsing due to external atmospheric pressure when in a vacuum.
What is the pressure rating of 100R4?
The inner diameter size of SAE 100R4 hydraulic suction hose ranges from 3/4″ to 4″. The working pressure is 58PSi ~ 305PSI, which is a low-pressure hydraulic hose. The larger the inner diameter, the smaller the pressure it can withstand. The bursting pressure is four times the working pressure, and it has a higher safety factor.
Not recommended for high-pressure hydraulic systems.
What is the bend radius of SAE 100R4?
The inner diameter size of SAE 100R4 hydraulic suction hose ranges from 3/4″ to 4″, the bend radius is 120mm~610mm, because its reinforcement layer is high-strength textile, it has a small bending radius.
Which hoses are suitable for suction and discharge?
The SAE100R4 hose has an oil-resistant inner tube and a weather-resistant outer tube. Its multi-layer fabric is reinforced with spiral steel wire. Its durable construction ensures reliable suction and delivery of hydraulic oil, making it a versatile choice in the energy, agriculture and construction industries.
In addition to SAE 100R4 hydraulic suction hose, there are some other hoses that are also suitable for suction and discharge, such as: PVC suction and discharge hose, composite suction and discharge hose, spiral steel wire reinforced PVC hose, PVC fiber reinforced hose, silicone reinforced hose.
What are the differences between SAE100R4 and ordinary oil hoses?
SAE100R4 and ordinary oil hoses have some significant differences in structure and application.
SAE 100 R4 suction and discharge oil hoses are commonly used for oil suction and discharge under negative pressure. Therefore, the reinforcement layer not only contains high-strength fibers but also a steel wire spiral reinforcement, SAE100R4 hydraulic hoses have good resistance to negative pressure and do not collapse.
However, ordinary oil hoses only have a fiber braided or wound reinforcement layer, without a steel wire spiral structure, and can only withstand positive pressure, making them prone to collapsing under oil suction conditions.
