Frequently Asked Questions
Q What do I.D., O.D., and R.O.D. stand for in hydraulic hose specifications?
I.D. refers to the Inner Diameter of the hose, which determines the flow capacity. O.D. stands for Outer Diameter, which indicates the total thickness of the hose. R.O.D. refers to the Reinforcement Outer Diameter, representing the diameter over the reinforcing wire or textile braid.
Q What is the relationship between MAX W.P. and MIN B.P.?
MAX W.P. (Maximum Working Pressure) is the maximum pressure a hose can safely operate under continuously. MIN B.P. (Minimum Burst Pressure) is the threshold pressure at which the hose will physically rupture. In this technical specification, the safety factor ratio is 4:1 (e.g., 210 bar Working Pressure vs. 840 bar Burst Pressure).
Q Why is the MIN B.R. (Minimum Bend Radius) critical during installation?
The Minimum Bend Radius (MIN B.R.) is the smallest radius to which a hose can be bent without kinking, restricting flow, or damaging the internal reinforcements. Bending the hose below the specified limit (ranging from 50mm to 150mm depending on the size) will significantly reduce its service life.
Q How does the dash size relate to the metric dimensions of the hose?
Dash size is a standard measurement representing the inner diameter of a hose in sixteenths of an inch. For example, a Dash 4 corresponds to an I.D. of 6.3mm (1/4 inch), and a Dash 16 corresponds to an I.D. of 25.0mm (1 inch).
Q Are these hoses suitable for high-pressure systems?
Yes, all listed hose sizes maintain a high maximum working pressure of 210 bar (3,045 psi) and a minimum burst pressure of 840 bar (12,180 psi), making them ideal for heavy-duty high-pressure hydraulic applications.
