A swage mechanism operable to expand an inner diameter of tubing including a housing defining a longitudinal axis, and a plurality of jaws coupled to the housing and movable radially outward relative to the longitudinal axis for selectively gripping an interior of the tubing. The jaws each include a first cam surface. The swage mechanism further includes a ram having a cylindrical portion and a frusto-conical head portion, and an arbor that is coupled to the housing and having a second cam surface. The frusto-conical head portion of the ram is insertable into the tubing to expand the inner diameter of the tubing. The second cam surface of the arbor is engageable with the first cam surface of each of the jaws to move the jaws toward or away from the longitudinal axis, wherein the second cam surface moves in a direction along the longitudinal axis.
