Angular displacement for hose assemblies with elbow fittings on both ends shall have the angular displacement between elbows, measured counter-clockwise from the cente
9、rline 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 45 flange, far end 90 flange. 3. Angular displacement shall be mea
10、sured in degrees 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. F
