SAE AS4459 Revision B, March 1, 2013
(R) Fittings, Tube, Fluid System 3000 psig (21 000 kPa) Rated Pressure,
Externally Swaged, Specification For
Description / Abstract:
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 °F or -55 to 70 °C), and II (-65 to 275 °F or -55 to
135 °C) of AS2001.
This specification 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 AS5902. Table 10 shows applicable aerospace fitting part number standard and tubing materials and operating pressures.
Classification
Fittings shall be of the following types and system pressure classes as specified:
Classes:
Class B (1500 psi): Maximum supply pressure is 1500 psig (10 500 kPa).
Class D (3000 psi): Maximum supply pressure is 3000 psig (21 000 kPa).
