Frequently Asked Questions
What do I.D. and O.D. represent in the specification table?
I.D. stands for Inner Diameter, which determines the flow capacity of the fluid inside the hose. O.D. stands for Outer Diameter, which is critical for calculating installation clearance and selecting matching hose clamps or fittings.
What is the difference between MAX W.P. and MIN B.P.?
MAX W.P. (Maximum Working Pressure) is the maximum pressure at which the hose can safely operate continuously. MIN B.P. (Minimum Burst Pressure) is the threshold pressure at which the hose is expected to physically fail or rupture, typically designed with a 4:1 safety factor relative to working pressure.
Why is the MIN B.R. (Minimum Bend Radius) value important?
The Minimum Bend Radius indicates the sharpest curve to which the hose can be bent without kinking, damaging the internal reinforcement structure, or restricting fluid flow. Bending the hose below this value will shorten its service life significantly.
How does the hose size affect its pressure rating?
Generally, as the Inner Diameter (I.D.) of the hose increases, its Maximum Working Pressure decreases. For example, a 1/4" hose has a MAX W.P. of 400 bar, whereas a larger 1" hose has a MAX W.P. of 165 bar.
What unit systems are used for pressure and weight measurements?
Pressure ratings are provided in both bar and psi (Pounds per Square Inch) to suit different international standards. The weight of the hose is measured in kilograms per meter (kg/m) to help calculate the load of the overall assembly.
