Abstract: A packoff assembly for sealing an annulus between an inner tubular member and an outer tubular member including a sealing means rotatably connected to a packing nut. The sealing means includes an upper actuation ring rotatably retained on the packing nut. A sealing member having a ring-like metal body is rotatably mounted on the upper actuation ring with a roller ball connection which permits limited relative axial movement between the upper actuation ring and the sealing member. A lower actuation ring is rotatably mounted on the body of the sealing member by another roller ball connection which permits limited relative axial movement between the lower actuation ring and the body of the sealing member. The metal body of the sealing member includes a pair of frustoconical-shaped outer seal lips and a pair of frustoconical-shaped inner seal lips. An elastomeric seal ring is disposed on the body of the sealing member between each pair of metal seal lips.
