A joint assembly for coupling a first conduit to a second conduit includes a first collar configured to be mounted on the first conduit and a second collar configured to be mounted on the second conduit. The second collar may have a central longitudinal axis that is generally aligned with a z-axis. An inner bushing may be coupled to the first collar and have a generally convex surface, and an outer bushing may be coupled to the second collar and have a generally concave surface. The generally convex surface and the generally concave surface may mate with one another and be configured for relative movement such that the first collar gimbals in an xy-plane.
