 V-packings and V-packing kits are primarily used for sealing rods subjected to axial motion. A packing kit consists of the number of V-packings needed for the particular application requirements as well as a base and end ring. In case there is a risk of gap extrusion under high pressure loads, the base and end rings may
also be made of metallic materials. To achieve pre-defined sealing forces and adjustment of the packing in case of thermal expansion, installation of an axially acting spring (compression spring or cup spring) is necessary.
