The present application pertains to a braided dual-sided compression packing seal, methods for producing and using such a seal, and apparatuses suitable for producing such a seal. The braided dual-sided compression packing seal is made up of two or more different materials that are braided together in such a way that, in cross-section, the compression packing seal has an asymmetrical configuration relative to a first axis that is substantially perpendicular to the longitudinal axis and is substantially perpendicular to a side of the compression packing seal. Accordingly, when viewed in a cross-sectional plane, the compression packing seal may expose substantially only a first material along a first side of the seal, and substantially only a second material along a second side of the seal.

The present application pertains to a compression packing seal including a braided dual-sided jacket, methods for producing and using such a seal, and apparatuses suitable for producing such a seal. The compression packing seal is made up of a core and a jacket braided round the core. The jacket may include two or more different materials that are braided together in such a way that, in cross-section, the jacket has an asymmetrical configuration relative to a first axis that is substantially perpendicular to the longitudinal axis and is substantially perpendicular to a side of the jacket. Accordingly, when viewed in a cross-sectional plane, the jacket may expose substantially only a first material along a first side, and substantially only a second material along a second side.

The present invention provides a packing yarn that utilizes a non-metal woven reinforcement that provides lateral as well as longitudinal strength while improving the wear characteristics of the yarn material. To increase the support provided by the woven reinforcement, the yarn material and woven reinforcement are folded together such that the woven reinforcement is substantially coextensive with the yarn material in the resulting packing yarn.

Gland packing yarn

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.
