Q1 What is the relationship between the working pressure and burst pressure for these hoses?
The hoses maintain a safety factor ratio of approximately 4:1. The minimum burst pressure (MIN B.P.) is four times the maximum working pressure (MAX W.P.). For example, the 1/4" hose has a working pressure of 3,000 psi and a burst pressure of 12,000 psi.
Q2 How does the hose weight change as the inner diameter increases?
The weight increases progressively with the hose size. It ranges from 0.24 kg/m for the smallest 3/16" size up to 4.00 kg/m for the largest 3" size.
Q3 What is the minimum bend radius (MIN B.R.) for the 1/2" hose?
The minimum bend radius for the 1/2" hose (size -10) is 140 mm. This indicates the smallest radius to which the hose can be bent safely without kinking.
Q4 Which size offers the highest pressure ratings?
The 3/16" (-4) and 1/4" (-5) hoses offer the highest pressure ratings, both supporting a maximum working pressure of 207 bar (3,000 psi) and a minimum burst pressure of 827 bar (12,000 psi).
Q5 What are the min and max Outer Diameters (O.D.) for the 1-1/8" hose?
For the 1-1/8" hose (size -20), the Outer Diameter (O.D.) ranges from a minimum of 37.3 mm to a maximum of 38.9 mm.
Q6 What are the specifications for the largest hose size in this chart?
The largest size is 3" (size -48), which has an I.D. of 76.2–77.8 mm, an O.D. of 89.3–91.7 mm, a maximum working pressure of 14 bar (200 psi), a minimum burst pressure of 55 bar (800 psi), a minimum bend radius of 838 mm, and weighs 4.00 kg/m.
