3.4.1.1.4 Receptacle shell. The single-hole mount receptacle shall be provided with an O-ring panel
seal and nut with provisions for locking.
3.4.1.1.5 Coupling connection. The coupling ring of threaded and bayonet types shall be straight
knurled or fluted and designed to assist in mating and unmating contacts as the coupling ring is tightened

and contact arrangement without the use of tools. The coupling ring shall be mechanically retained on
the plug shell and shall provide positive retention of the plug and receptacle by solid shoulders on the
coupling ring and plug shell. A plug with a bayonet coupling shall couple to its mating receptacle by
rotating the coupling ring through 120° maximum in accordance with MIL-STD-1554. The threaded
coupling ring shall have three .35 inch (8.89 mm) diameter safety wire holes equally spaced.
