What is the range of sizes available for this hose?
The hose is available in nominal inner diameters (I.D.) ranging from 6.3 mm (1/4") up to 25.4 mm (1").
What is the maximum working pressure (Max W.P.) of the 1/4" hose?
The 1/4" (6.3 mm) hose has a maximum working pressure of 225 bar, which is equivalent to 3,260 psi.
What is the safety factor between Burst Pressure (B.P.) and Working Pressure (W.P.)?
The hoses feature a 4:1 safety factor. The Minimum Burst Pressure (Min B.P.) is exactly four times the Maximum Working Pressure (Max W.P.) across all sizes.
How does the minimum bend radius (Min B.R.) change with the hose size?
The minimum bend radius increases as the hose diameter increases. It starts at 75 mm for the 1/4" hose and goes up to 230 mm for the 1" hose.
What are the weights of the smallest and largest hoses per meter?
The 1/4" hose weighs approximately 0.18 kg/m, while the larger 1" hose weighs approximately 0.77 kg/m.
What do the abbreviations I.D., R.O.D., and O.D. stand for?
I.D. stands for Inner Diameter, R.O.D. stands for Reinforcement Outer Diameter (diameter over the reinforcement layer), and O.D. stands for Outer Diameter (the overall outside diameter of the hose).
