Offset Motion Chart

Live hose length for offset motion in metal hose

For fluoropolymer hose assemblies, factor the live length shown below by 2.5, then add the fitting lengths to arrive at "OAL".

Important note
The values shown in the blue text are applicable to static bends only. For intermittent flexing, the Offset Motion should never be greater than 25% of the center-line bend radius

Assembly Length (live and overall length)
The live length and the overall length of the assembly must be determined to complete the design. The live length is the flexible portion of an assembly. After the live length has been determined the overall length is determined by adding the dimensions for the end fitting.
