PTFE Graphite Packing
The packing is woven of graphite PTFE yarn twisted through a mixture of PTFE dispersion resins and fine graphite powder plus moderate amount of heat-resistant lubricant.
PTFE Graphite Packing with oil
Packing: Packing made of 100% g PTFE yarns, and re-impregnated with a silicone lubricant with density about 1.6g/cm3.
Applications
For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators.
Especially designed for services involving surface speeds and temperature higher than those normally specified for pure PTFE packings.
Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, fuming nitric acid and other strong oxidizing agents.
It is also against water, steam, petroleum derivatives, vegetable oil and solvents.
It is a braided packing made of PTFE yarn containing graphite particles and anti-corrosive lubricant. It is recommended for shafts for almost all chemicals. Stability and long service lift are achieved by low friction coefficient. It has great tear strength and high thermal conductivity. This self-lubricating packing does not score the shaft and minimizes sleeve replacement cost. It can be used to seal alkalis, solvents, water, steam, acids except strong oxidizing acids(aqua regia, fuming nitric acid, fuming sulfuric acid, etc.) forcentrifugal pumps, autoclaves agitators, mixers, etc.
Spec: 3.0mm - 50mm
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.
GRAPHITE PACKING BEST CHOICE FOR HIGH TEMPERATURE AND HIGH PRESSURE APPLICATIONS
Graphite Packing is made of reinforced graphite. The reinforcing materials are various fibers or wires including steel wire, copper wire, nickel wire, carbon fiber, pre-oxidized wire, glass yarn and other reinforced graphite wire.
Graphite packing resists all chemicals across the entire pH range (except fuming sulfuric acid, aqua regia, fuming nitric acid and fluorine). It also has great lubricity and excellent thermal conductivity.
It is widely used in acid and oil production industries Its resilience makes it the perfect sealant for the fuel, chemical, and gas industries.

- Graphite Tape Packing is the packing that compressed and molded in a certain dimension for easy installation.
- The graphite's self-lubrication capability and low coefficient of friction allow to use in a wide range without giving damage on the reciprocating and rotary shaft.
- If you want to disassemble only gland without disassembling pump and valve, you can just cut it and deliver.
- You can get better sealing effects if you use with ALS910C, ALS900G and ALS955W depending on the use purpose.
Expanded graphite packing is made by weaving expanded graphite yarns reinforced with cotton yarns through the center. It features excellent self-lubrication and thermal conductivity, with a low coefficient of friction, strong versatility, good flexibility, high strength, and is less likely to wear the shaft. Depending on different working conditions, it can be reinforced with different non-metallic and metallic wires. It is widely used in valves, pumps, expansion joints, mixers, agitators and other equipment in petrochemical, power plants, steel mills and other industries. Application media include hot water, high-temperature and high-pressure steam, heat exchange media, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquids, etc.
The chemical properties of graphite are very stable, high temperature resistance, corrosion resistance, and good conductivity.Therefore, graphite can be used as refractory material, sealing material, conductive material, and is widely used in high temperature metallurgy, sand finding, paint lubricant, pencil lead, pigment, polishing agent, petrochemical industry, synthetic fiber, heater and other industries.
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.
