Abstract
In one exemplary embodiment of the present disclosure a fluid coupling assembly defining an axial direction, a radial direction, and a circumferential direction is provided. The fluid coupling assembly includes a male coupling including a first MC attachment interface, a second MC attachment interface, and an outer surface extending along the circumferential direction; a ferrule coupling including an FC attachment interface pressed against the first MC attachment interface, a lip extending along the radial direction, and an outer surface extending along the circumferential direction to define a circular shape; and a nut coupling including an NC attachment interface rotatably engaged with the second MC attachment interface, a flange extending along the radial direction and pressed against the lip of the ferrule coupling, and an inner surface extending along the circumferential direction to define a circular shape; wherein the outer surface of the male coupling, the outer surface of the ferrule, or the inner surface of the nut coupling includes a plurality of non-resilient protrusions spaced along the circumferential direction for contacting an opposing surface and increasing a loose…
