Abstract
Abstract An oil seal for corrosive media has an annular housing of a plastic which chemically has conparatively little resistance and an annular sealing element, arranged fixedly on the housing, of chemically- resistant polytetrafluoroethylene. The sealing element is arranged on the housing such that the PTFE material of the sealing element covers the parts of the plastic housing which normally come into contact with the corrosive media, as a protective layer. <IMAGE>
