Frequently Asked Questions
What is the relationship between Dash size, DN, and Inches?
Dash size is a standard measurement representing the hose inner diameter (I.D.) in sixteenths of an inch (e.g., -4 is 4/16" or 1/4"). DN (Nominal Diameter) is the metric equivalent designation in millimeters, while Inches represent the standard imperial measurement of the hose's inner diameter.
How do Max W.P. and Min B.P. values correlate?
Max W.P. (Maximum Working Pressure) is the maximum pressure at which the hose is designed to operate safely during continuous service. Min B.P. (Minimum Burst Pressure) is the pressure at which the hose will structurally fail or burst. The safety factor for these hoses is typically 4:1 (Burst Pressure is 4 times the Working Pressure).
Why is the Minimum Bend Radius (Min B.R.) important?
The Minimum Bend Radius is the smallest radius to which a hose can be bent without kinking, damaging the reinforcement layer, or restricting fluid flow. Bending a hose beyond its specified Min B.R. can significantly shorten its lifespan and lead to premature failure.
What is the difference between I.D. and O.D.?
I.D. (Inner Diameter) measures the empty space inside the hose where the fluid flows, which determines the flow rate capacity. O.D. (Outer Diameter) measures the entire cross-section of the hose, including the inner tube, reinforcement layers, and outer cover. O.D. is critical for selecting the correct fittings, sleeves, and clamps.
How does hose weight affect my application?
Hose weight (measured in KG/M) is an important consideration for systems where overall weight is restricted, such as in mobile hydraulic machinery, long suspended hose runs, or aerospace applications. Lightweight hoses reduce system loads and can offer better flexibility.
