RE: MIL-F-85421 3DDave (Aerospace) 14 Jun 14 12:22 Rynglok is advertised as compatible with the MIL-F-85421 system of fittings, based on performance. They list male and female. Look for EATON CORPORATION Aerospace TF100-17 June, 2004 If you like, the Mil specs are still available on Assist QuickSearch.
