| Abstract: | The paper introduces development of "O"ring in which the inside and outside parts are semicovered with PTFE film. The technigue is successfully applied to non-oil lubricating seals, hydraulie and pneumatic reciprocation seal. By using it, the friction coefficient can be reduced and the sealing reliability and service life are improved as well. |
