Minimum Live Length
ISO10380 Guidance
To meet the full potential of the hose assembly the international standard ISO10380 states that:
"braided metal hose assemblies shall be of such a length that there is at least one complete revolution(braid pitch) of braid along the length of the hose".
At Flexmetallic we can manufacture hose assemblies to whichever length you require but will always recommend that the guidance within ISO10380 is followed. The chart below shows the minimum recommended length each size of hose should be cut at for it to meet its full potential of working pressure and temperature ranges.
| Hose bore | Cut length (mm) | Standard live length(mm) |
|---|---|---|
| 1/4" | 35 | 15 |
| 3/8" | 50 | 20 |
| 1/2" | 60 | 30 |
| 3/4" | 85 | 35 |
| 1" | 100 | 50 |
| 1 1/4" | 140 | 80 |
| 1 1/2" | 165 | 105 |
| 2" | 200 | 130 |
| 2.5" | 240 | 170 |
| 3" | 320 | 270 |
