Measure angle between fittings, counterclockwise. Both fittings pointing to 6 o'clock to be specified as zero degrees (0 ). Specifying position: Suffix the hose assembly part number with the number of degrees in the angle.(Example: 191060E0185C180; 180 twist angle.) The standard tolerance is 2 . Note: Elbow hose fittings shown in this catalog are Stratoflex standard type designs. If your installation requires a fitting of a different angle or connection, submit a print for Stratoflex Engineering evaluation. Measurement of Flareless Hose Assemblies NAS 1760 nipple end design is the standard supplied by Stratoflex for flareless hose fittings. Flareless hose assembly length L is measured from end of nipple to end of nipple. To convert end to end to gage point to gage point measurement, subtract from L the appropriate B or C dimension shown in table below for each end fitting. The figures and table below give a comparison of NAS 1760 nipple end design and the radius seal end design. Dash A B C Size NAS Radius Diff. NAS Radius Diff.
