A cable fitting includes a gland nut, a body, and a chuck. The gland nut includes first threads, an axial gland bore, and a first sloped surface along a portion of the axial gland bore. The body includes second threads to receive the first threads, an axial body bore, and a second sloped surface along a portion of the axial body bore. The chuck includes multiple segments joined in a hinged fashion to create a ring. Each of the multiple segments includes a distal end tapered surface and a proximal end tapered surface. When the gland nut is advanced onto the body, the first sloped surface applies a first compressive force to the distal end tapered surfaces, and the second sloped surface applies a second compressive force to the proximal end tapered surfaces. The compressive forces cause inward deformation of the chuck to secure a cable within an axial pathway.
