Q: What is the difference between Hose I.D. and O.D.?
I.D. (Inner Diameter) measures the internal width of the hose, which determines fluid flow capacity. O.D. (Outer Diameter) measures the entire cross-section including the cover and reinforcement, which is critical for selecting compatible fittings and clamps.
Q: How do you convert Dash sizes to inches for these hoses?
Dash sizes represent the inner diameter of the hose in sixteenths of an inch. For example, a -4 Dash size corresponds to 4/16" (or 1/4" Inch), while a -16 Dash size corresponds to 16/16" (or 1 Inch).
Q: What is the relationship between MAX W.P. and MIN B.P.?
MAX W.P. (Maximum Working Pressure) is the limit for safe, continuous operation. MIN B.P (Minimum Burst Pressure) is the pressure at which physical failure occurs. The safety factor ratio in this chart is 4:1 (Burst Pressure is 4 times the Working Pressure).
Q: Why is the Minimum Bend Radius (MIN B.R.) critical during installation?
The Minimum Bend Radius is the tightest curve a hose can make without kinking or restricting flow. Bending the hose beyond the specified MIN B.R. (e.g., 20mm for -2 size) can damage the internal structure and shorten its lifespan.
Q: What does DN stand for in the specifications?
DN stands for Nominal Diameter (Diameter Nominal). It is a European/International metric sizing standard (ISO 6708) that corresponds closely to the physical internal diameter of the hose in millimeters.
