Ptfe graphite packing Interlock braid, using ptfe/graphite yarn and a high temperature break-in lubricant 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 packings. It is chemically inert over the entire 0-14 ph range with these exceptions: molten alkali metals, flourides, aleum, fuming nitric acid, aqua regia, and other strong oxidizing agents. Gh-120 is an excellent general service and corrosive service packing. It is commonly used in pumps, valves, rotating and reciprocating shafts, mixers and agitators, and is especially designed for services involving surface speeds and temperatures higher than those that can be handled by pure ptfe packing. 2kg or 5kg per spool

Graphite packing This packing is manufactured from high purity flexible graphite that is expanded and formed into a braidable yarn and then braided without binders or wire reinforcement. It also contains corrosion inhibitor to prevent the electrical-chemical reaction. The finished product retains all the inherent benefits of flexible graphite: heat resistance, chemical inertness, low friction, self lubrication, and conforms readily. The outstanding properties of gh-110 make it a truly multi-service packing capable of a wide variety of uses throughout a plant. It may be used in valves, pumps, expansion joints, mixers and agitators in the hostile environments of hydrocarbon processing, pulp and paper, power generation, metal-working and other industries where effective sealing is vital. 2kg or 5kg per spool

Pure carbon braided packing The packing is manufactured from pure carbon yarn, which is interlock braided and impregnated with ptfe and graphite particles which fill voids, block leakage, and act as a break-in lubricant. The end product has a low coefficient of friction and tends to wear more evenly than most braided packings. It handles water, steam, boiler feed, and aqueous solutions of acids and alkalis. In service, it seats quickly and does not require extensive break-in adjustments. It is commonly used for high speed pumps, blowers, dryers, high temperature valves, and furnace gasket. 2kg or 5kg per spool in general.

PTFE packing It is a interlock braided packing manufactured from pure ptfe yarns pretreated with ptfe dispersion, plus a break-in lubricant to reduce the coefficient of friction. This is a dimensionally stable packing, yet relatively soft and pliable, which has excellent lubricating and running characteristics. It handles all acids, alkalis, and most chemicals, with the exception of molten alkali metals. It is suited for high speed rotary shaft service and is also commonly used on reciprocating pumps, mixers, agitators, and reactors. 2kg or 5kg per spool
