This specification covers the requirements for Aircraft Hydraulic, Self-Sealing, Quick Disconnect Couplings for use in 5000 and 8000 lbf/in2 (gage) lightweight hydraulic systems.
This SAE Aerospace Standard (AS) establishes the general requirements for a miniature probe type self-sealing, self-aligning, non-locking coupling intended for aerospace liquid cooling systems. The AS5072/slash sheets define the specific performance and dimensional requirements.
This specification covers the requirements for aircraft, hydraulic couplings, self sealing one side only, for use in Type II hydraulic systems (-65°F to +275° temperature range) as defined by MIL-H-5440. The purpose being to connect a hose or tube to a standard MS33656, MS33514 or MIL-F-85421 fitting and provide the self sealing feature on that side only.
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 -65 to 400 °F and at 125 psi operating pressure.
