Frequently Asked Questions
What is the relationship between the Dash size and the Hose Inner Diameter (I.D.)?
The Dash size represents the inner diameter of the hose in sixteenths of an inch. For example, a -4 dash size equals 4/16" (which simplifies to 1/4" I.D.), while a -16 dash size equals 16/16" (which is 1" I.D.).
How do I convert the Working Pressure values from BAR to PSI?
To convert pressure from BAR to PSI, you multiply the BAR value by 14.5038. For instance, a maximum working pressure of 210 BAR is equivalent to approximately 3,045 PSI as specified in the chart.
What is the significance of the Minimum Burst Pressure (Min B.P.)?
The Minimum Burst Pressure is the pressure threshold at which the hose is design-tested to structurally fail or rupture. It is typically calculated with a 4:1 safety factor relative to the Maximum Working Pressure (Max W.P.) to ensure safe operation.
Why is the Minimum Bend Radius (Min B.R.) critical during installation?
The Minimum Bend Radius is the smallest radius to which a hose can be bent without kinking, restricting fluid flow, or damaging the internal reinforcements. Bending the hose tighter than the specified Min B.R. will significantly shorten its service life.
How does weight (KG/M) scale with the size of the hose?
As the internal diameter (I.D.) and outer diameter (O.D.) increase, the amount of material and reinforcement structure increases, leading to a higher weight per meter. For example, the lightweight -2 hose weighs 0.06 KG/M, whereas the robust -16 hose weighs 0.51 KG/M.
