Abstract
A ferrule for a conduit fitting includes an interior wall extending along a central axis through the ferrule so that the ferrule can be installed over a conduit end. A first axial side of the ferrule defines a first end portion, a first end camming surface disposed on the first end portion at a first angle with respect to the central axis, and a first end driven surface disposed at a second angle with respect to the central axis, the second angle being greater than the first angle. A second axial side of the ferrule defines a second end portion, a second end camming surface disposed on the second end portion at a third angle with respect to the central axis, the third angle being substantially equal to the first angle, and a second end driven surface disposed at a fourth angle with respect to the central axis, the fourth angle being substantially equal to the second angle. A central boss portion extends radially outward to define a radially outermost surface at an axial center point of the ferrule.
