Abstract
A system for coupling a ball fitting connected to a first tubing to a socket fitting connected to a second tubing. A first coupling forms an aperture having a diameter that is larger than the diameter of the ball fitting, and receives the ball fitting. The first coupling forms an annular race, with an annular surface disposed between the annular race and the aperture. First split ring pieces are assembled into a first ring that forms an aperture having a diameter that is smaller than the diameter of the ball fitting, and receives the first tubing. The first ring forms an annular ridge that engages the annular race, and aligns the first split ring pieces. The annular surface applies uniform axial pressure to a first surface of the first ring. The first ring has a second surface opposing the first surface that applies uniform axial pressure to a back portion of the ball fitting. A second coupling forms an aperture having a diameter that is larger than the diameter of the socket fitting, and receives the socket fitting. The second coupling forms an annular race, with an annular surface disposed between the annular race and the aperture. Second split ring pieces are assembled into a se…
