This paper examines some of the technical achievements obtained at НИИСУ (Russian Aviation Institute for Standardization and Unification). These results make it possible to replace the rubber ring seal with a mechanical face seal with longer life and less leakage. The influence of friction pair material on the leakage of working fluid and the wear state of friction pair under various conditions are discussed. The schematic diagram of the testing equipment of mechanical surface sealing is given. The leakage of mechanical surface seal and the influence of temperature and pressure Influence of working fluid leakage. The research shows that as the temperature of the working fluid increases, the amount of leakage increases; the condition of the mechanical face seal components such as friction pair and rubber ring after the test is also studied
