Coupling Assembly, Threadless, Flexible, Self-Locking, Fixed Cavity, High Conductivity, Self-Bonding, Part Specification
|Publication Date:||1 September 2017|
This SAE Aerospace Standard (AS) defines the requirements for a threadless, flexible, high conductive self-bonding coupling assembly which, when installed on defined ferrules, provides a flexible connection for joining ducting and components in pressurized fluid systems. The assembled coupling is designed to provide interchangeability of parts and components between qualified manufacturers for use from -65 to +265 °F at 130 psi nominal operating pressures and for the service life of the aircraft system.
FAR 23.954, FAR 25.901, FAR 25.954 and FAR 25.981 certification requirements have identified the need for high current capable flexible fluid assembled couplings. The coupling assembly does not require inspection and maintenance to remain current capable for the life of the aircraft.
This specification provides two test philosophies necessary for low pressure couplings:
