Graphite-Filled PTFE Gasket is a high-performance sealing component manufactured from PTFE compounded with graphite filler. Compared with virgin PTFE, the graphite-filled formulation provides improved wear resistance, better dimensional stability, reduced creep, and enhanced performance in demanding sealing applications while retaining the excellent chemical resistance and low-friction characteristics of PTFE.
JAIFUXIN manufactures graphite-filled PTFE gaskets in standard and custom dimensions for pumps, valves, flanges, chemical processing equipment, fluid handling systems, and industrial machinery. Gaskets can be produced according to drawings, samples, flange standards, or application-specific requirements.
