HOW TO DETERMINE CORRECT ASSEMBLY LENGTH

For most assemblies, the correct assembly length may be determined by direct measurement of the equipment or a drawing. Minimum bend radii as shown in the hose specification tables should be observed.
To determine the length of hose needed in making assemblies with permanent or reusable couplings, subtract Dimension “C” (Cut off factor) for each coupling from the required overall assembly length. Dimension “C” may be found in the coupling specification tables.

Assemblies are measured to the end of the seal.

Remember that hydraulic hose under pressure will elongate up to 2% of its length or contract up to 4% depending on pressure, type and size. Sufficient allowance should be made to permit such changes in length.
