QWhat do I.D., R.O.D., and O.D. represent in the table?
I.D. stands for Inner Diameter, R.O.D. stands for Reinforcement Outer Diameter, and O.D. stands for Outer Diameter. These measurements define the structural dimensions of the hose in millimeters (mm) and inches.
QHow does the Maximum Working Pressure (MAX W.P.) change with hose size?
Generally, as the Inner Diameter (I.D.) of the hose increases, the Maximum Working Pressure (MAX W.P.) decreases. For example, the 3/16" hose supports up to 415 bar (6020 psi), whereas the larger 2 1/2" hose supports up to 70 bar (1015 psi).
QWhat is the safety factor between Working Pressure and Burst Pressure?
The Minimum Burst Pressure (MIN B.P.) is designed with a safety factor of approximately 4:1 relative to the Maximum Working Pressure (MAX W.P.). For instance, the 1/4" hose has a MAX W.P. of 400 bar and a MIN B.P. of 1600 bar.
QWhy is the Minimum Bend Radius (MIN B.R.) critical during installation?
The Minimum Bend Radius (MIN B.R.) indicates the smallest radius to which a hose can be bent without kinking or damaging its inner reinforcement structure. Exceeding this limit can reduce hose life and pressure performance.
QHow does the weight of the hose correlate with its size?
The weight of the hose (measured in kg/m) increases as the hose diameter increases. The lightest hose in this specification is the 3/16" size at 0.27 kg/m, while the heaviest is the 2 1/2" size at 3.47 kg/m.
