Measurement of Flareless Hose Assemblies NAS 1760 nipple end design is the standard supplied by Stratoflex. Flareless hose assembly length L is measured from end of nipple to end of nipple. To convert 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. Flareless hose fittings end to end to gage point to gage point. AS4209 Nipple end design is the standard supplied by Stratoflex on beam seal hose assembly length L is measured from end of nipple corner to end of nipple corner.End of nipple corner is the theoretical point of positive stop on external thread fitting end.Mates with AS4207/MIL-F-85421 beam seal hose fittings.
