graphite ptfe gland packing without oil

       

     Packing (packing compilation) is also called packing, usually by the soft wire woven, usually the sectional area of a square or rectangular, circular strips of material filled in the sealing cavity, so as to achieve sealing. Packing seal is the first cotton fiber plug in to prevent fluid leakage channels mainly used as seal leakage, water lifting machinery. As the filler of extensive sources, easy processing, low cost, reliable sealing, simple operation, so it is still in use today. Now the packing is widely used in centrifugal pump, compressor, vacuum pump, mixer shaft and propeller seal, piston pump, reciprocating compressor, reciprocating seal refrigeration machine well, all kinds of rotary sealing valve stem.

     PTFE series including white PTFE packing, black PTFE packing, PTFE white woven aramid fiber packing, PTFE black woven aramid fiber packing, PTFE preoxidized fiber packing, white four fluorine silicone oil immersion packing, white four fluorine dipping heart packing. The series packing with PTFE as the main material with excellent chemical stability., corrosion resistance, sealing, high viscosity lubrication and good anti-aging endurance. Can work at -180℃~+260℃ temperature for a long time, in addition to the molten metal and liquid sodium fluoride, capable of all other chemicals in aqua regia in boiling and is not change. Mainly used for sanitary does not allow pollution working conditions, corrosion resistance and high speed is high, easy to wear and other conditions.
