As hydraulics steadily become more and more complicated, it is imperative to understand the importance of the role that hoses play in hydraulic systems. In order to route a hose into increasingly compact spaces, pressures have increased while hose dimensions have decreased.
Additionally, suppliers provide hundreds of varying styles and types of hydraulic hoses, and thousands of fittings, to choose from. How will you know which hoses and fittings are the right choice when it is time to replace a hydraulic hose assembly? Southern Fluidpower can help you make this determination, with some essential tips to consult when you build a hose assembly.
What dash size or I.D. does the application need
The inside diameter (I.D.) of the hose, also known as the dash size, is the fluid power industry standard for measuring hydraulic hoses, and is measured in sixteenths of an inch. The I.D. can be manually measured or it can also be found on the hose layline. Determining the I.D. is essential in order to establish the system’s proper flow velocity. If a flow is too high, it will cause damage to the system, drops in pressure, and hose leakage. Conversely, if a flow is too slow, it will cause the system to perform sluggishly.
