GFO fiber for pump packing from W.L. Gore & Associates, Inc. is a high performance composite material designed and engineered specifically for use as a compression packing. With a 20-plus year history of trouble-free performance, this packing delivers an unmatched level of assurance and confidence. GFO fiber packing applications include sealing shafts on high-speed pumps, mixers, agitators, or any other equipment with rotating or reciprocating shafts. Because of its durability and long life, GFO fiber packing is consistently high performing. It doesn't get hard or brittle, thereby minimizing shaft wear. Additionally, its excellent lubricity and high thermal conductivity keep it cool-running, even after extended periods of continuous use. Gore has certified a select group of packing braiders to provide the highest quality GFO fiber packing: American Braiding & Manufacturing Co. (Howell, NJ); ChemStar, Inc. (Mulberry, FL); Palmetto, Inc. (Denton, MD); SEPCO (Alabaster, AL); and Robco (Quebec, Canada).
