SAE J517 orientation offset elbow ends hose assembly

Date:Jul 05, 2019

SAE J517 specifies ORIENTATION OF OFFSET ELBOW ENDS IN A HOSE ASSEMBLY.

For double elbow assemblies, it is imperative that the method of description and measurement provide the desired displacement rather than its mirror image. To achieve this, either end may be selected as the reference point, provided angle displacement is determined appropriately (clockwise or counterclockwise) for the reference selected.

Displacement angle may have any value up to 360 degrees. Please note that making the angle determination in the wrong direction will result in an unacceptable part.

Unless otherwise specified, a tolerance of ±3 degrees is acceptable for assembly lengths up to 610 mm inclusive, and ±5 degrees for assembly lengths over 610 mm.

Try to avoid use of double elbow hose assemblies. Twisting of the hose during installation may occur. The relative location of the natural curvature in the hose may induce a twist during pressure cycling. Twisted hose may reduce the life of the hose assembly.
