Industrial 165R Compression Packing 9/16in 5lb

ChemStar 165R compression packing is a graphite-filled PTFE fiber braid designed for sealing rotating pump shafts, offered in 9/16 inch diameter and packaged as a 5 lb spool. The 165R variant adds reinforced corners to help prevent roll and extrusion, giving stable gland behavior under high-temperature and chemically aggressive service. The 165 family is described as flexible and pliable, and will not harden, swell or become brittle over time, a trait that supports reliable, long-cycle sealing in demanding pumping applications. Used as gland packing for centrifugal pumps and related stuffing-box maintenance, this graphite-infused packing delivers effective thermal conductivity alongside chemical resistance that characterizes ChemStar's 165 formulations. Catalog entries commonly show S5311045 for the 9/16 in, 5 lb size, with other 165R sizes such as 3/4 in, 5 lb appearing under related part numbers in supplier catalogs.
