This standard specifies the dimensional characteristics of the 60° interface for adaptors, threaded, with
lockring, assembly with elastomer O-ring, for aerospace applications.
This standard applies to all adaptors, threaded, with lockring, assembled to EN 2607 and used in fluid
systems with a nominal pressure of 28 000 kPa for which a metric-size coupling with a 60° conical sealing
surface has been selected.
