Frequently Asked Questions
What do I.D., R.O.D., and O.D. stand for in the specifications?
I.D. stands for Inner Diameter, which is the measurement of the internal flow path. R.O.D. stands for Reinforcement Outer Diameter, measuring the diameter over the reinforced layer. O.D. stands for Outer Diameter, which is the total outside diameter of the hose cover.
What is the relationship between MAX W.P. and MIN B.P.?
MAX W.P. (Maximum Working Pressure) is the maximum safe operating pressure for the hose. MIN B.P. (Minimum Burst Pressure) is the physical pressure limit at which the hose will rupture during safety testing, typically designed at a 4:1 safety factor relative to the working pressure.
How does the Minimum Bend Radius (MIN B.R.) affect installation?
The Minimum Bend Radius (MIN B.R.) is the smallest radius to which the hose can be bent without kinking, restricting flow, or reducing its overall service life. Bending a hose tighter than the specified limit can cause structural failure.
Are the pressure values provided in both metric and imperial units?
Yes, the table provides pressure measurements in both bar and psi (pounds per square inch) to accommodate different global engineering standards and system requirements.
Why is the weight of the hose (kg/m) an important specification?
Hose weight (measured in kilograms per meter) is critical for calculating total system weight loads, designing support structures, and ensuring compatibility in dynamic or suspended applications where weight limits apply.
