Frequently Asked Questions
Q:What do I.D., R.O.D., and O.D. stand for in the specifications?
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 physical dimensions of the hose layers from the inside to the outside.
Q:How does the working pressure (MAX W.P.) compare to the burst pressure (MIN B.P.)?
The Minimum Burst Pressure (MIN B.P.) is designed to be exactly 4 times the Maximum Working Pressure (MAX W.P.). For example, a hose with a working pressure of 276 bar (4000 psi) has a burst pressure safety limit of 1104 bar (16000 psi).
Q:What is the impact of hose size on the maximum working pressure?
Smaller hose sizes (from 3/8" to 1" I.D.) support a higher working pressure of 276 bar (4000 psi). As the hose diameter increases to 1 1/4" and above, the maximum working pressure decreases, down to 172 bar (2500 psi) for the 2" hose.
Q:Why is the Minimum Bend Radius (MIN B.R.) important for installation?
The Minimum Bend Radius (MIN B.R.) indicates the smallest radius to which the hose can be bent without kinking, damaging the reinforcement, or restricting flow. Larger hoses require a larger bending radius (up to 630 mm for the 2" size).
Q:How does the weight of the hose change relative to its size?
The weight increases proportionally with the hose size. The smallest 3/8" hose weighs 0.6 kg/m, whereas the largest 2" hose weighs 4.25 kg/m due to the increased material volume and reinforcement layers.
