Abstract
A packing assembly includes a clip configured to hold a packing stack in a desired arrangement on a longitudinal axis. The clip includes upper arms and lower arms through which the packing stack and slide laterally into and out of the clip. The upper arms and lower arms prevent radial movement of the packing stack and can further prevent axial movement of the packing stack relative to the clip. The clip facilitates installation of the packing stack on a piston by shifting the assembled packing stack axially onto the piston and then pulling laterally off of the packing stack while leaving the packing stack on the piston rod.
