  • Single lock and double lock couplings having a locking ring with identifying indicia and methods of use and assembly
    Patent number: 9334995
    Abstract: Couplings for use with mating couplings with locking rings. A stem coupling may have a coupling head configured to attach with a head portion of the mating coupling, a stem mated to the coupling head where the stem has a threaded portion on an outer surface, and a retractable locking sleeve positioned on a portion of the coupling head. The retractable locking sleeve may have a locked position and an unlocked position for preventing and permitting the coupling head to attach to or detach from the mating coupling. The stem coupling includes a stem locking ring having a first position preventing axial movement of the locking sleeve and a second position permitting axial movement of the locking sleeve. The stem locking ring may also include at least one of a color and indicia to alert a user to a type of media for which the stem coupling is intended.
