The present invention is an improved seal (10) for use in preventing leakage in a variety of applications where two components move relative to one another in a sliding fashion. The seal (10) of the present invention employs an elastic inner member (12), coated with a chemically resistant fluoropolymer film (14). The film both protects the inner elastic member from chemical attack as well as provide a low coefficient of friction for an improved sliding seal. The seal of the present invention is particularly suitable for use in applications such as floating roofs on chemical storage tanks. |
