A braided packing has a number of longitudinal strands around which a braid strand is wound in a lattice pattern to form a substantially square braid. The longitudinal strands include at least two lubricant sink strands, the lubricant sink strands having a material composition and configuration to give the lubricant sink strands a higher lubricant absorbency than the other longitudinal strands and the braid strand. The packing is immersed in a lubricating fluid which is absorbed and retained in higher amounts by the lubricant sink strands, thereby providing a long-lasting source of lubricant for the overall packing during use.
