Abstract
A packing assembly comprises a plurality of adjacent solid, compressible, non-resilient, low friction packing rings having cylindrical sealing surfaces forming a continuous sealing surface along the shaft and each solid ring having a pair of converging generally radially extending walls thereby defining a space between the adjacent walls of each pair of adjacent rings and resilient rings in the space between adjacent solid rings.
