This document specifies performance and quality requirements for the qualification and manufacturer of 24° cone fittings to ensure reliable performance in aircraft hydraulic systems. This document specifies baseline criteria for the design and manufacture of system fittings that are qualification tested on engines. This document covers fittings of temperature types and pressure classes specified in MA2001.
This document 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 -54 to 204 °C and at 862 kPa operating pressure. AS coupling components referenced herein have been qualified to AS1650. Ferrules referenced herein are inch ferrules adapted to metric tubing.
This supplement forms a part of the Aerospace Standard AS1946, Hose Assembly, Polytetrafluoroethylene, Metallic Reinforced, up to 1500 psi and 450 °F, Hydraulic and Pneumatic, and shall be used to identify hose assembly standards citing this procurement specification.
