ABSTRACT OF THE DISCLOSURE A packing arrangement for a shaft within a body, particularly for a valve shaft within a valve bonnet, providing a packing chamber between the valve stem and the valve bonnet and a spring loaded packing injector having a packing material reservoir at a leading end thereof. The packing injector provides a cylinder capped by a nozzle. The nozzle screws into a packing port of the valve. The injector provides a piston mounted at a front end of a rod. The piston fits tightly and reciprocally within the nozzle. The reservoir is defined by the nozzle and piston. The rod protrudes out of a back end of the cylinder, indicating the amount of packing material residing within the reservoir in the packing injector. The injector replenishes the packing material normally lost during operation of the valve.
