A fluid line fitting having a pipe, tube or hose connection or a through hole to accommodate a bolt, fluid passage on one end. the other end must have an internal or external quick disconnect feature for connecting a mating part to form a quick disconnect coupling assembly. the fitting may incorporate a self-sealing feature for the purpose of automatically shutting off the flow of fluid when disconnected from its mating half. for self-sealing fittings with an external or internal threaded disconnect end, see coupling half, self-sealing. see also, connector, multiple, fluid pressure line.
