Frequently Asked Questions
What do I.D. and O.D. mean in the specifications?
I.D. stands for Inner Diameter, which determines the fluid carrying capacity and flow velocity of the hose. O.D. stands for Outer Diameter, which is critical for selecting the correct hose fittings, clamps, and ensuring proper clearance in tight spaces.
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 operate safely and continuously. MIN B.P. (Minimum Burst Pressure) is the pressure at which the hose is tested to fail or rupture. The burst pressure is typically 4 times the working pressure to ensure safety.
Why is MIN B.R. (Minimum Bend Radius) important?
The Minimum Bend Radius is the smallest radius to which a hose can be bent without kinking, damaging the reinforcement layers, or restricting fluid flow. Bending a hose beyond this limit will significantly reduce its service life and pressure rating.
How does the hose weight affect my application?
Hose weight (measured in kg/m) is crucial for calculating the overall load of a hydraulic system, especially in dynamic applications where the hose moves constantly, or in heavy machinery where weight limits are strictly monitored.
How do I choose the correct hose size from this chart?
You should match the required flow rate and system pressure of your application with the corresponding Inner Diameter (I.D) and Maximum Working Pressure (MAX W.P.) listed in the specification table. Ensure the working pressure of the hose meets or exceeds your system's peak operating pressure.
