This aerospace specification defines the requirements for a threadless, flexible, self-bonding coupling assembly which, when installed on machined fixed cavity ferrules, provides a flexible connection for joining tubing and components in aircraft fuel, vent or other systems. This assembled coupling, hereafter referred to as the assembly, is designed for use from -65 to +400 °F and at 125 psig nominal operating pressure.
Rationale: AS1650 Rev. B corrects the placement and title of paragraph 4.6.6. Revision B adds PRI QPL/QML requirements, deletes gunfire vibration requirements, reduces impulse peak pressure requirements and provides a general document update.
