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.
Rationale: Revised to specify lower bending stress for sizes -48 and above, relocated strain gages near the holding clamp, clarified o-ring criteria and revised repeated assembly requirements for sizes -06 thru -12.
