This SAE Aerospace Standard (AS) establishes the requirements for externally swaged tube-fitting assemblies used in aircraft fluid systems in the following pressure classes: B (1500 psi or 10 500 Kpa), and D (3000 psi or 21 000 kPa), and in temperature types I (-65 to 160 degree F or -55 to 70 degree C), and II (-65 to 275 degree F or -55 to 135 degree C) of AS2001.

This specificaiton covers a common Cres, titanium, and aluminum fittings that may be used for a range of operating pressures up to 3000 psi with different tubing materials and tubing wall thicknesses and is assembled with the same tooling in accordance with AS 5902.
