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.
- Size : From 4 x 4 mm to 50 x 50mm
- Packaging standard: in coils of 1kg, 2kg, 3kg, 5kg to 10 kg, other weight on request; as precut length.
Technical PTFE Graphite Packing
- Pressure Range
+ Rotating: 15 to 20 bar
+ Reciprocating: 100 bar
+ Static: 150 to 200 bar
- Shaft speed: 12 to 16 m/s
- Density: 1.4 to 1.6g/cm3
- Temperature:－150 to +280 Deg.C
- PH range: 0 ~ 14
Application of PTFE Graphite Packing
- 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.
What is A Graphite PTFE Packing ?
Graphite PTFE Packings, it is known as GFO Packing. The packings are soft, with low density. There are no free particles of graphite on surface and therefore no contamination can occur.

Different Type of Graphite PTFE Packing
• CGFO Packing
CGFO packing is made by import style high quality graphite ptfe yarn, it contains more graphite content compared with normal graphite PTFE yarn.
• Graphite PTFE Filament Packing
Braided from sintered and high stretched Graphite PTFE multifilament yarns. Within PTFE impregnation. Good resistance to compression and extrusion, high structural and cross-sectional density.
• Pure Graphite PTFE Packing
Braided from pure Graphite PTFE yarn without any lubrication. It is non-contaminating packing.
• Pure Graphite PTFE Packing with Oil
Braided from the Graphite PTFE yarn which with special lubrication, designed for dynamic.
