Abstract
A fluid system component is provided that includes first and second elements configured to be removably engaged with each other and defining a fluid passageway when engaged. The first element defines three grooves, each of which includes a terminal portion. Correspondingly, the second element includes three engagement members each of which is configured and arranged to be received in, and travel along, a corresponding groove. The presence of a predetermined line pressure in the fluid passageway forces each engagement member into the terminal portion of the corresponding groove, so as to substantially foreclose disengagement of the first and second elements until the fluid pressure in the fluid passageway has reached a predetermined magnitude.
