Angular displacement for hose assemblies with elbow fittings on both ends shall have the angular displacement between elbows, measured counter-clockwise from the centerline

10、 of the nearest fitting, positioned at six-o clock, to the centerline of the other fitting (see SAE-J517). 2. The near end of the connector shall be put in numerical order relative to the far end (see table I). Example: Near end adapter 45, far end 90. 3. Angular displacement shall be measured in de

11、grees with a tolerance of 3 for lengths up to 2 feet (61 cm) and 5 for all lengths over 2 feet (61 cm). 4. The angular displacement shall be expressed in two digits number of degrees divided. 5. Making the angular determination in the wrong direction will result in an unacceptable part. FIGURE 3. El
