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.
Hydraulic hose SAE 100R4 can be used for petroleum and water based hydraulic fluids. It widely serves in various machines like tractor, crane, road roller. In addition, it’s ideal for other vehicles such as car, bus, harvester and many others.
We can not only produce oil suction and discharge hose, but also provide corresponding hose coupling to maintain the sealing of the pipeline.
We has our own production plant, the daily output can reach 50,000 meters hoses. There are more than 50 employees, everyone will abide by professional norms and complete the work with quality and quantity. We have 20 years of experience in the production of hydraulic hoses. We will take every order seriously and treat every customer with care.
Not only will the raw materials and production process be strictly controlled, but also the finished products will be tested for pulse and wear resistance. For low-temperature high-pressure hoses, this special pipe will be subjected to strict low-temperature bending tests. Ensure that every hose is qualified.
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 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.
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.
