Pure graphite rings are used in all technological fields where high temperatures, aggressive media or a combination thereof are encountered. Here the advantages of graphite are clearly visible. For this reason fixtures, valves, pumps or exhaust systems have been equipped with pure graphite rings for decades.
Today the development of these products continues on. Modern production processes allow the fabrication of various ring geometries. In addition the rings may be equipped with additional accessories, such as stainless steel caps (one side or two sides), impregnation (PTFE or copper paste), or the choice of special graphite foils (such as APX foils for use in temperatures over 450°C).
