It is braided by high strength carbon fiber continuous filament under softening treatment, and dipped by graphite and special lubricant, to form a dense structure, having a good self-lubrication, to effectively avoid leakage.

Product application: As the pump and valve filler under high temperature and high pressure situation, it can be singly used, and can be used together with 560 and 561 graphite ring. As the end ring, it can prevent extrusion. When combinational used with 241 pure graphite die-pressed filler ring, it can be used in the dry running equipments, e. g. Blower and air compressor. It is widely used for multiple mediums as water, steam, acid, and base, etc. In power station, refinery, boiler works. The 572 Ni-wire reinforced-type is generally used for steam turbine, high temperature electric valve, and generally applied high temperature and high pressure valve.
