3R 730
BRAIDED PACKING
EXPANDED PTFE GRAPHITE

ISO 9001 : 2000 Certified

3R 730 braided packing is an interlock braid, utilizing EG2 PTFE/graphite yarn and a high temperature break-in lubricant. EG2 yarn is formed from expanded PTFE in which fine particles of pure graphite have been encapsulated. The resulting packing combines the chemical resistance of PTFE with the heat dissipation characteristics of graphite, thus allowing much higher shaft speeds than conventional PTFE braided packing.

Applications //

The 3R 730 is an excellent general service and corrosive service packing. This braided packing is chemically inert over the entire 0-14 pH range with these exceptions: molten alkali metals, fluorides, aleum, fuming nitric acid, aqua regia and other strong oxidizing agents. The 3R 730 it is commonly used in pumps, valves, rotating and reciprocating shafts, mixers and agitators. It is especially designed for services involving surface speeds and temperatures higher than those that can be handled by pure PTFE packing.
