We can provide a comprehensive guide to 3/8 hydraulic hoses, including pressure ratings, optional types and their common applications. Please feel free to contact us.
Before assembling the hydraulic hose, the size of the hydraulic hose is very important. This size directly determines the flow rate and pressure loss of the oil in the hose, as well as the matching degree with the joint. Common sizes include 3/8 hydraulic hose, 1/4″ hydraulic hose, 1/2″ and 1 inch hose.
What size is 3/8 hydraulic hose?
3/8 hydraulic hose usually refers to a hydraulic hose with an inner diameter of 3/8 inches. This hose is expressed as 3/8″ inch, which is approximately 9.3 mm-10.1 mm when converted to metric units.
3/8″ hydraulic hose is suitable for conveying water-based, petroleum-based and biodegradable hydraulic oils. It can withstand higher pressures, usually between 1131 psi (SAE100R3) and 6090 psi (SAE100R15). It is commonly used in construction machinery, agricultural machinery, industrial equipment and other occasions that require hydraulic transmission.
Hydraulic Hose Size Chart
In the detailed introduction of each of our products, there is a size chart which includes the inner diameter, outer diameter, working pressure, bursting pressure, bending radius, length and weight of the hydraulic hose.
The figure below is the specification size of the EN853 1SN hydraulic hose, marking the inner diameter and outer diameter of the hose and the pressure when the inner diameter is 3/8 inches.
