The paper presents the conditions and the results of the research on the composite materials based on PTFE (polytetrafluorethylene) for sliding rings of the seal. The original tribological stand was applied in the experimental investigations. The test specimens in the form of rings were made of thirteen different PTFE composite materials which contained graphite, bronze and molybdenum disulfide. Frictional characteristics of changes in operating parameters of the tested sliding rings, i.e. friction moment and friction surface temperature - over time, unit pressures and liquid pressure - over time are presented.
