Hose Assembly – Installation Guide
The following diagrams show proper hose installations which provide maximum performance and cost savings. Consider these examples in determining length of a specific assembly.
When determining the length of hose assemblies, provide sufficient length to prevent bending strain from localising at the back of the coupling. In the diagram below, measurement “B” allows for a strain section of hose beyond the coupling to prevent concentration of bending strain. “T” designates the amount of travel. “A” indicates the smallest diameter to which hose should be bent.
Overall length = B+1.57A+T
