AS7510B
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 25.603, FAR 25.605, FAR 25.609, FAR 25.613, 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 or maintenance to remain current capable for the life of the aircraft.

ARP4784B
This SAE Aerospace Recommended Practice (ARP) is intended to provide definitions of and recommendations for drawing limits pertaining to surface and edge features on machined metal fluid fittings and is subject to change to keep pace with experience and technical advances. The subject includes: features, descriptions and definitions, examples, limits, inspection methods and standard drawing callouts where applicable. Fittings may retain unmachined material surfaces that exhibit similar surface features as machined surfaces and may be inspected to the same criteria. These unmachined surfaces may also contain unique features that are addressed separately. See Figure 1 for the relationship of surface and edge features.
