Orientation of Offset Elbow Ends
in a Suction and Return 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 counter
clockwise) for the reference selected.
As shown in Figure 1, with the centerline of
the near end as a base reference, angular
displacement is measured counter-clockwise
to the centerline of the far end.
Displacement angle may have any value from
0 to 359 degrees. Please note that making the
angle determination in the wrong direction will
result in a 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.

As shown in Figure 2, with the centerline of the far end as a base reference, angular displacement is measured clockwise to the centerline of the near end.
