Joint assembly

A joint assembly comprising:

• a housing having a side wall with a cylindrical inner side surface area and a lip which projects radially inward of said cylindrical inner side surface area;
• a movable member having a ball end portion disposed in said housing;
• and
• an annular seal disposed in said housing and having an axial length extending from an outer surface to an inner surface, said annular seal including an annular metal reinforcing ring and an annular body of polymeric material which encloses said annular metal reinforcing ring, said annular body of polymeric material having a cylindrical outer side surface extending substantially over said axial length of said annular seal which is disposed in sealing engagement with said cylindrical inner side surface area on said housing and an inner side surface disposed in sealing engagement with an outer surface area disposed on said ball end portion of said movable member at a location radially inward of said annular metal reinforcing ring and axially inward of said lip.
