Frequently Asked Questions
What is the maximum working pressure (Max W.P.) for a 6.3mm hose?
The 6.3mm metric inner diameter hose (Dash size 4) has a maximum working pressure of 345 bar, which is equivalent to 5,000 psi.
How does the minimum bend radius (Min B.R.) change with the hose size?
The minimum bend radius increases as the hose diameter gets larger. It ranges from 50 mm for the smallest 6.3 mm hose up to 210 mm for the 31.5 mm hose, ensuring safe operation without kinking.
What safety factor is used between Working Pressure and Burst Pressure?
The technical specifications demonstrate a standard 4:1 safety factor. For example, the 6.3 mm hose has a Max Working Pressure of 345 bar and a Min Burst Pressure of 1380 bar (exactly 4 times the working pressure).
What is the weight per meter of a 19.0 mm (Dash 12) hose?
The 19.0 mm inner diameter hose (Dash size 12) has a nominal weight of 0.87 kg/m.
What do the terms I.D., R.O.D., and O.D. represent in the specification table?
I.D. stands for Inner Diameter, R.O.D. stands for Reinforcement Outer Diameter (the diameter over the reinforcement layer), and O.D. stands for Outer Diameter (the total external diameter of the hose).
Which hose size supports the highest working pressure?
The 6.3 mm (Dash 4) hose supports the highest working pressure of 345 bar (5,000 psi). As the inner diameter of the hose increases, the maximum working pressure rating decreases, down to 112 bar (1,625 psi) for the 31.5 mm (Dash 20) hose.
