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.

Guide for Choosing a Minimum Wall Thickness of Tubing for Use with Weld Fittings Coded for a Range of Wall Sizes
2023-09-11
CURRENT
ARP4698A
This SAE Aerospace Recommended Practice (ARP) is intended as a guide for choosing a minimum wall thickness of tubing, based only on pressure, for use with welded tube fitting ends that have a “tube wall code” covering a range of tube wall thicknesses. These wall thicknesses are based on burst pressure with an arbitrary additional safety factor. If the weld fitting user has already established the required minimum wall thickness for given performance conditions, this guide does not apply.

Definitions and Limits, Metal Material Defects and Surface and Edge Features, Fluid Couplings, Fittings, and Hose Ends

CURRENT
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.

Performance Standard for Tube Support Loop-Cushioned Clamp
2022-05-16
CURRENT
AS1553B
This standard covers heat and corrosion resistant steel loop clamps with a woven steel wire cushion that is attached to the clamp by spot welding and is intended for use in applications up to 1200 °F (649 °C).
