This SAE Aerospace Information Report (AIR) contains information relative to stresses and loads developed in tubes caused by tube deflections encountered in misaligned installations. Users are advised that when calculating the stresses and loads of a tubing system, the yield strength of existing loop clamp material is significantly lower than the tubing materials specified herein and should be considered.

This document covers flexible and semiflexible, reinforced and unreinforced air hoses fabricated from laminated and impregnated fabric, intended for use in aircraft heating, air conditioning, ventilating, defrosting, and/or deicing systems.

This SAE Aerospace Standard (AS) establishes the requirements for externally swaged titanium tube fittings on titanium and CRES tubing with flareless separable fitting for use in hydraulic supply and return aerospace fluid systems up to operating pressure of 5080 psig (35 000 kPa) maximum and an operating temperature range of -65 to +275 °F (-54 to +135 °C). This specification covers a common 5080 psi pressure titanium fitting that may be used for a range of operating pressures up to 5080 psi with different tubing materials and tubing wall thicknesses, and is assembled with the same tooling in accordance with AS5959. The fitting operating pressure is based on the fitting thread pitch. Extra fine pitch for 5080 psi operating pressure and fine pitch for operating pressures 3000 psi and less. Table 12 shows applicable aerospace fitting part number standard and tubing materials and operating pressures.

This SAE Aerospace Standard (AS) establishes the requirements for axially swaged titanium fittings on titanium, CRES, and aluminum tubing with flareless separable fitting ends for use in hydraulic supply and return aerospace fluid systems up to operating pressure of 5080 psig (35000 kPa) maximum. The operating temperature range for titanium tubing and CRES tubing is -65 to +275 °F (-54 to +135 °C) and the operating temperature range for aluminum return system tubing is -65 to +225 °F (-54 to +107 °C). This specification covers a common 5080 psi pressure titanium fitting that may be used for a range of operating pressures up to 5080 psi with different tubing materials and tubing wall thicknesses and is assembled with the same tooling in accordance with AS5959. The flareless fitting operating pressure is based on the fitting thread pitch. Extra fine pitch is used for 5080 psi operating pressure and fine pitch for operating pressures 3000 psi and less.

This document is prepared as an aid in the selection of clamping devices and their use in aerospace equipment for the installation and support of tubing and wiring. For recommended installation practices, refer to ARP994.

This specification covers a polytetrafluoroethylene resin in the form of extruded and sintered flexible tube reinforced with wire braid.

This specification establishes requirements for automatic shutoff, quick-disconnect coupling assemblies for fuel and oil lines.

This SAE Aerospace Standard (AS) defines the requirements for a threadless, flexible, self-bonding coupling assembly which, when installed on machined fixed-cavity ferrules, provides a flexible connection for joining tubing and components in aircraft fuel, vent, or other systems. This assembled coupling, hereafter referred to as the assembly, is designed for use from -65 to +400 °F and at 125 psig nominal operating pressure. AS1650 was not designed for the new certification requirements for flammable leakage zones and fuel tanks for lightning protection and assembly redundancy. As such, their use and installation may require additional efforts and equipment to support new FAA CFR compliance. The AS7510 flexible coupling should be the preferred coupling for use in flammable leakage zones and fuel tanks that require service life and functionality for lightning protection and part redundancy.

This SAE Aerospace Standard (AS) specifies test methods for tube-fitting assemblies used in aircraft fluid systems in the following pressure classes: B (1500 psi or 10500 kPa), D (3000 psi or 21000 kPa), E (4000 psi or 28000 kPa), and J (5000 psi or 35000 kPa) and in temperature types I (-65 to 160 °F or -55 to 70 °C), II (-65 to 275 °F or -55 to 135 °C), and III (-65 to 400 °F or -55 to 200 °C) of AS2001. This document applies each time that it is referred to in a procurement specification or other definition document. Fluids and materials used for the tests are listed in Section 2.

This specification defines the requirements for a threaded rigid coupling assembly, which utilizes ferrule type machined tube end fittings, to join tubing and components in aircraft fuel, vent, and other systems. This coupling assembly is designed for use from −65 to 200 °F and at 125 psig operating pressure.
