Abstract
A sealing system for sealing an annulus. The annulus is defined by a cylindrical interior and a cylindrical exterior within, and axially movable relative to, the cylindrical interior. The sealing system includes an inner seal (to surround and sealingly engage the cylindrical exterior), a seal support (to surround, and axially support, the inner seal), an outer seal (to surround the seal support and sealingly engage the seal support and the cylindrical interior), a first support ring (to sit behind an outer periphery of the outer seal), and a back stop (to surround the cylindrical exterior and axially support the seal support and the first ring).
