261A / Coupling half,self-sealingWhat is the formal definition of this item?
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 external or internal thread for connecting a mating part to form a self-sealing coupling assembly. the fitting has either a self-sealing feature for the purpose of automatically shutting off the flow of fluid when disconnected from its mating half, or, if it has no self-sealing feature, is specifically designed to mate with a fitting with a self-sealing feature. for self-sealing fittings with a quick disconnect end, see coupling half, quick disconnect. for fluid line fittings without a self-sealing feature, see coupling (as modified).
